+Version 2.23
+
+* Unicode 8.0.0 Support: Character encoding, character type info, and
+  transliteration tables are all updated to Unicode 8.0.0, using new
+  and/or improved generator scripts contributed by Mike FABIAN (Red Hat).
+  These updates cause user visible changes, such as the fixes for bugs
+  89, 16061, and 18568.
+
+* sched_setaffinity, pthread_setaffinity_np no longer attempt to guess the
+  kernel-internal CPU set size.  This means that requests that change the
+  CPU affinity which failed before (for example, an all-ones CPU mask) will
+  now succeed.  Applications that need to determine the effective CPU
+  affinities need to call sched_getaffinity or pthread_getaffinity_np after
+  setting it because the kernel can adjust it (and the previous size check
+  would not detect this in the majority of cases).
+
+* The fts.h header can now be used with -D_FILE_OFFSET_BITS=64.  With LFS
+  the following new symbols are used: fts64_children, fts64_close,
+  fts64_open, fts64_read and fts64_set.
+
+* getaddrinfo now detects certain invalid responses on an internal netlink
+  socket.  If such responses are received, an affected process will
+  terminate with an error message of "Unexpected error <number> on netlink
+  descriptor <number>" or "Unexpected netlink response of size <number> on
+  descriptor <number>".  The most likely cause for these errors is a
+  multi-threaded application which erroneously closes and reuses the netlink
+  file descriptor while it is used by getaddrinfo.
+
+* A defect in the malloc implementation, present since glibc 2.15 (2012) or
+  glibc 2.10 via --enable-experimental-malloc (2009), could result in the
+  unnecessary serialization of memory allocation requests across threads.
+  The defect is now corrected.  Users should see a substantial increase in
+  the concurent throughput of allocation requests for applications which
+  trigger this bug.  Affected applications typically create create and
+  destroy threads frequently.  (Bug 19048 was reported and analyzed by
+  Ericsson.)
+
+* There is now a --disable-timezone-tools configure option for disabling the
+  building and installing of the timezone related utilities (zic, zdump, and
+  tzselect).  This is useful for people who build the timezone data and code
+  independent of the GNU C Library.
+
+* The obsolete header <regexp.h> has been removed.  Programs that require
+  this header must be updated to use <regex.h> instead.
+
+* The obsolete functions bdflush, create_module, get_kernel_syms,
+  query_module and uselib are no longer available to newly linked binaries;
+  the header <sys/kdaemon.h> has been removed.  These functions and header
+  were specific to systems using the Linux kernel and could not usefully be
+  used with the GNU C Library on systems with version 2.6 or later of the
+  Linux kernel.
+
+* Optimized string, wcsmbs and memory functions for IBM z13.
+  Implemented by Stefan Liebler.
+
+* Newly linked programs that define a variable called signgam will no longer
+  have it set by the lgamma, lgammaf and lgammal functions.  Programs that
+  require signgam to be set by those functions must ensure that they use the
+  variable provided by the GNU C Library and declared in <math.h>, without
+  defining their own copy.
+
+* The minimum GCC version that can be used to build this version of the GNU
+  C Library is GCC 4.7.  Older GCC versions, and non-GNU compilers, can
+  still be used to compile programs using the GNU C Library.
+
+Security related changes:
+
+* An out-of-bounds value in a broken-out struct tm argument to strftime no
+  longer causes a crash.  Reported by Adam Nielsen.  (CVE-2015-8776)
+
+* The LD_POINTER_GUARD environment variable can no longer be used to disable
+  the pointer guard feature.  It is always enabled.  Previously,
+  LD_POINTER_GUARD could be used to disable security hardening in binaries
+  running in privileged AT_SECURE mode.  Reported by Hector Marco-Gisbert.
+  (CVE-2015-8777)
+
+* An integer overflow in hcreate and hcreate_r could lead to an
+  out-of-bounds memory access.  Reported by Szabolcs Nagy.  (CVE-2015-8778)
+
+* The catopen function no longer has unbounded stack usage.  Reported by
+  Max.  (CVE-2015-8779)
+
+* The nan, nanf and nanl functions no longer have unbounded stack usage
+  depending on the length of the string passed as an argument to the
+  functions.  Reported by Joseph Myers.  (CVE-2014-9761)
+
+* A stack-based buffer overflow was found in libresolv when invoked from
+  libnss_dns, allowing specially crafted DNS responses to seize control
+  of execution flow in the DNS client.  The buffer overflow occurs in
+  the functions send_dg (send datagram) and send_vc (send TCP) for the
+  NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC
+  family.  The use of AF_UNSPEC triggers the low-level resolver code to
+  send out two parallel queries for A and AAAA.  A mismanagement of the
+  buffers used for those queries could result in the response of a query
+  writing beyond the alloca allocated buffer created by
+  _nss_dns_gethostbyname4_r.  Buffer management is simplified to remove
+  the overflow.  Thanks to the Google Security Team and Red Hat for
+  reporting the security impact of this issue, and Robert Holiday of
+  Ciena for reporting the related bug 18665. (CVE-2015-7547)

+  18657, 18676, 18694, 18696, 18887.
+
+* Cache information can be queried via sysconf() function on s390 e.g. with
+  _SC_LEVEL1_ICACHE_SIZE as argument.
+
+* A buffer overflow in gethostbyname_r and related functions performing DNS
+  requests has been fixed.  If the NSS functions were called with a
+  misaligned buffer, the buffer length change due to pointer alignment was
+  not taken into account.  This could result in application crashes or,
+  potentially arbitrary code execution, using crafted, but syntactically
+  valid DNS responses.  (CVE-2015-1781)
+
+* The time zone file parser has been made more robust against crafted time
+  zone files, avoiding heap buffer overflows related to the processing of
+  the tzh_ttisstdcnt and tzh_ttisgmtcnt fields, and a stack overflow due to
+  large time zone data files.  Overly long time zone specifiers in the TZ
+  variable no longer result in stack overflows and crashes.
+
+* A powerpc and powerpc64 optimization for TLS, similar to TLS descriptors
+  for LD and GD on x86 and x86-64, has been implemented.  You will need
+  binutils-2.24 or later to enable this optimization.
+
+* Character encoding and ctype tables were updated to Unicode 7.0.0, using
+  new generator scripts contributed by Pravin Satpute and Mike FABIAN (Red
+  Hat).  These updates cause user visible changes, such as the fix for bug
+  17998.
+
+* CVE-2014-8121 The NSS backends shared internal state between the getXXent
+  and getXXbyYY NSS calls for the same database, causing a denial-of-service
+  condition in some applications.
+
+* Added vector math library named libmvec with the following vectorized x86_64
+  implementations: cos, cosf, sin, sinf, sincos, sincosf, log, logf, exp, expf,
+  pow, powf.
+  The library can be disabled with --disable-mathvec. Use of the functions is
+  enabled with -fopenmp -ffast-math starting from -O1 for GCC version >= 4.9.0.
+  Shared library libmvec.so is linked in as needed when using -lm (no need to
+  specify -lmvec explicitly for not static builds).
+  Visit <https://sourceware.org/glibc/wiki/libmvec> for detailed information.
+
+* A new fmemopen implementation has been added with the goal of POSIX
+  compliance. The new implementation fixes the following long-standing
+  issues: BZ#6544, BZ#11216, BZ#12836, BZ#13151, BZ#13152, and BZ#14292. The
+  old implementation is still present for use be by existing binaries.
+
+* The 32-bit sparc sigaction ABI was inadvertently broken in the 2.20 and 2.21
+  releases.  It has been fixed to match 2.19 and older, but binaries built
+  against 2.20 and 2.21 might need to be recompiled.  See BZ#18694.
+
+* Port to Native Client running on ARMv7-A (--host=arm-nacl).
+  Contributed by Roland McGrath (Google).
+
+* The header <regexp.h> is deprecated, and will be removed in a future
+  release.  Use of this header will trigger a deprecation warning.
+  Application developers should update their code to use <regex.h> instead.
+
+  This header was formerly part of SUS, but was deprecated in 1994 and
+  removed from the standard in 2001.  Also, the glibc implementation
+  leaks memory.  See BZ#18681 for more details.
+
+Version 2.21
+
+* The following bugs are resolved with this release:
+
+  6652, 10672, 12674, 12847, 12926, 13862, 14132, 14138, 14171, 14498,

+  17801, 17803, 17806, 17834, 17844, 17848, 17868, 17869, 17870, 17885,
+  17892.
+
+* CVE-2015-1472 CVE-2015-1473 Under certain conditions wscanf can allocate
+  too little memory for the to-be-scanned arguments and overflow the
+  allocated buffer.  The implementation now correctly computes the required
+  buffer size when using malloc, and switches to malloc from alloca as
+  intended.
+
+* A new semaphore algorithm has been implemented in generic C code for all
+  machines. Previous custom assembly implementations of semaphore were
+  difficult to reason about or ensure that they were safe. The new version
+  of semaphore supports machines with 64-bit or 32-bit atomic operations.
+  The new semaphore algorithm is used by sem_init, sem_open, sem_post,
+  sem_wait, sem_timedwait, sem_trywait, and sem_getvalue.
+
+* Port to Altera Nios II has been contributed by Mentor Graphics.
+
+* Optimized strcpy, stpcpy, strncpy, stpncpy, strcmp, and strncmp
+  implementations for powerpc64/powerpc64le.
+  Implemented by Adhemerval Zanella (IBM).
+
+* Added support for TSX lock elision of pthread mutexes on powerpc32, powerpc64
+  and powerpc64le.  This may improve lock scaling of existing programs on
+  HTM capable systems.  The lock elision code is only enabled with
+  --enable-lock-elision=yes.  Also, the TSX lock elision implementation for
+  powerpc will issue a transaction abort on every syscall to avoid side
+  effects being visible outside transactions.
+
+* Optimized strcpy, stpcpy, strchrnul and strrchr implementations for
+  AArch64.  Contributed by ARM Ltd.
+
+* i386 memcpy functions optimized with SSE2 unaligned load/store.
+
+* CVE-2104-7817 The wordexp function could ignore the WRDE_NOCMD flag
+  under certain input conditions resulting in the execution of a shell for
+  command substitution when the application did not request it. The
+  implementation now checks WRDE_NOCMD immediately before executing the
+  shell and returns the error WRDE_CMDSUB as expected.
+
+* CVE-2012-3406 printf-style functions could run into a stack overflow when
+  processing format strings with a large number of format specifiers.
+
+* CVE-2014-9402 The nss_dns implementation of getnetbyname could run into an
+  infinite loop if the DNS response contained a PTR record of an unexpected
+  format.
+
+* The minimum GCC version that can be used to build this version of the GNU
+  C Library is GCC 4.6.  Older GCC versions, and non-GNU compilers, can
+  still be used to compile programs using the GNU C Library.
+
+* The GNU C Library is now built with -Werror by default.  This can be
+  disabled by configuring with --disable-werror.
+
+* New locales: tu_IN, bh_IN, raj_IN, ce_RU.
+
+* The obsolete sigvec function has been removed.  This was the original
+  4.2BSD interface that inspired the POSIX.1 sigaction interface, which
+  programs have been using instead for about 25 years.  Of course, ABI
+  compatibility for old binaries using sigvec remains intact.
+
+* Merged gettext 0.19.3 into the intl subdirectory.  This fixes building
+  with newer versions of bison.
+
+* Support for MIPS o32 FPXX, FP64A and FP64 ABI Extensions.
+  The original MIPS o32 hard-float ABI requires an FPU where double-precision
+  registers overlay two consecutive single-precision registers.  MIPS32R2
+  introduced a new FPU mode (FR=1) where double-precision registers extend the
+  corresponding single-precision registers which is incompatible with the
+  o32 hard-float ABI.  The MIPS SIMD ASE and the MIPSR6 architecture both
+  require the use of FR=1 making a transition necessary.  New o32 ABI
+  extensions enable users to migrate over time from the original o32 ABI
+  through to the updated o32 FP64 ABI.  To achieve this the dynamic linker now
+  tracks the ABI of any loaded object and verifies that new objects are
+  compatible.  Mode transitions will also be requested as required and
+  unsupportable objects will be rejected.  The ABI checks include both soft and
+  hard float ABIs for o32, n32 and n64.
+
+  GCC 5 with GNU binutils 2.25 onwards:
+  It is strongly recommended that all o32 system libraries are built using the
+  new o32 FPXX ABI (-mfpxx) to facilitate the transition as this is compatible
+  with the original and all new o32 ABI extensions.  Configure a MIPS GCC
+  compiler using --with-fp-32=xx to set this by default.
+
+Version 2.20
+
+* The following bugs are resolved with this release:
+
+  6804, 9894, 11505, 12994, 13347, 13651, 14308, 14770, 15119, 15132, 15347,

+  16516, 16532, 16539, 16545, 16561, 16562, 16564, 16574, 16599, 16600,
+  16609, 16610, 16611, 16613, 16619, 16623, 16629, 16632, 16634, 16639,
+  16642, 16648, 16649, 16670, 16674, 16677, 16680, 16681, 16683, 16689,
+  16695, 16701, 16706, 16707, 16712, 16713, 16714, 16724, 16731, 16739,
+  16740, 16743, 16754, 16758, 16759, 16760, 16770, 16786, 16789, 16791,
+  16796, 16799, 16800, 16815, 16823, 16824, 16831, 16838, 16839, 16849,
+  16854, 16876, 16877, 16878, 16882, 16885, 16888, 16890, 16892, 16912,
+  16915, 16916, 16917, 16918, 16922, 16927, 16928, 16932, 16943, 16958,
+  16965, 16966, 16967, 16977, 16978, 16984, 16990, 16996, 17009, 17022,
+  17031, 17042, 17048, 17050, 17058, 17061, 17062, 17069, 17075, 17078,
+  17079, 17084, 17086, 17088, 17092, 17097, 17125, 17135, 17137, 17150,
+  17153, 17187, 17213, 17259, 17261, 17262, 17263, 17319, 17325, 17354.
+
+* Reverted change of ABI data structures for s390 and s390x:
+  On s390 and s390x the size of struct ucontext and jmp_buf was increased in
+  2.19. This change is reverted in 2.20. The introduced 2.19 symbol versions
+  of getcontext, setjmp, _setjmp, __sigsetjmp, longjmp, _longjmp, siglongjmp
+  are preserved pointing straight to the same implementation as the old ones.
+  Given that, new callers will simply provide a too-big buffer to these
+  functions. Any applications/libraries out there that embed jmp_buf or
+  ucontext_t in an ABI-relevant data structure that have already been rebuilt
+  against 2.19 headers will have to rebuilt again. This is necessary in any
+  case to revert the breakage in their ABI caused by the glibc change.
+
+* Support for file description locks is added to systems running the
+  Linux kernel. The standard file locking interfaces are extended to
+  operate on file descriptions, not file descriptors, via the use of
+  F_OFD_GETLK, F_OFD_SETLK, and F_OFD_SETLKW. File description locks
+  are associated with an open file instead of a process.
+
+* Optimized strchr implementation for AArch64.  Contributed by ARM Ltd.
+
+* The minimum Linux kernel version that this version of the GNU C Library
+  can be used with is 2.6.32.
+
+* Running the testsuite no longer terminates as soon as a test fails.
+  Instead, a file tests.sum (xtests.sum from "make xcheck") is generated,
+  with PASS or FAIL lines for individual tests.  A summary of the results is
+  printed, including a list of failing lists, and "make check" exits with
+  error status if there were any unexpected failures.  "make check
+  stop-on-test-failure=y" may be used to keep the old behavior.
+
+* The am33 port, which had not worked for several years, has been removed
+  from ports.
+
+* The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer
+  supported; they now act the same as _DEFAULT_SOURCE (but generate a
+  warning).  Except for cases where _BSD_SOURCE enabled BSD interfaces that
+  conflicted with POSIX (support for which was removed in 2.19), the
+  interfaces those macros enabled remain available when compiling with
+  _GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without any feature
+  test macros defined.
+
+* Optimized strcmp implementation for ARMv7.  Contributed by ARM Ltd.
+
+* Added support for TX lock elision of pthread mutexes on s390 and s390x.
+  This may improve lock scaling of existing programs on TX capable systems.
+  The lock elision code is only built with --enable-lock-elision=yes and
+  then requires a GCC version supporting the TX builtins.  With lock elision
+  default mutexes are elided via __builtin_tbegin, if the cpu supports
+  transactions. By default lock elision is not enabled and the elision code
+  is not built.
+
+* CVE-2014-4043 The posix_spawn_file_actions_addopen implementation did not
+  copy the path argument.  This allowed programs to cause posix_spawn to
+  deference a dangling pointer, or use an unexpected pathname argument if
+  the string was modified after the posix_spawn_file_actions_addopen
+  invocation.
+
+* All supported architectures now use the main glibc sysdeps directory
+  instead of some being in a separate "ports" directory (which was
+  distributed separately before glibc 2.17).
+
+* The NPTL implementation of POSIX pthreads is no longer an "add-on".
+  On configurations that support it (all Linux configurations), it's now
+  used regardless of the --enable-add-ons switch to configure.  It is no
+  longer possible to build such configurations without pthreads support.
+
+* Locale names, including those obtained from environment variables (LANG
+  and the LC_* variables), are more tightly checked for proper syntax.
+  setlocale will now fail (with EINVAL) for locale names that are overly
+  long, contain slashes without starting with a slash, or contain ".." path
+  components. (CVE-2014-0475)  Previously, some valid locale names were
+  silently replaced with the "C" locale when running in AT_SECURE mode
+  (e.g., in a SUID program).  This is no longer necessary because of the
+  additional checks.
+
+* On x86-64, the dynamic linker's lazy-binding support is now compatible
+  with application code using Intel MPX instructions.  (With all previous
+  versions, the MPX register state could be clobbered when making calls
+  into or out of a shared library.)  Note that while the new dynamic
+  linker is compatible with all known x86 hardware whether or not it
+  supports Intel MPX, some x86 instruction-set emulators might fail to
+  handle the new instruction encodings.  This is known to affect Valgrind
+  versions up through 3.9 (but will be fixed in the forthcoming 3.10
+  release), and might affect other tools that do instruction emulation.
+
+* Support for loadable gconv transliteration modules has been removed.
+  The support for transliteration modules has been non-functional for
+  over a decade, and the removal is prompted by security defects.  The
+  normal gconv conversion modules are still supported.  Transliteration
+  with //TRANSLIT is still possible, and the //IGNORE specifier
+  continues to be  supported. (CVE-2014-5119)
+
+* Decoding a crafted input sequence in the character sets IBM933, IBM935,
+  IBM937, IBM939, IBM1364 could result in an out-of-bounds array read,
+  resulting a denial-of-service security vulnerability in applications which
+  use functions related to iconv. (CVE-2014-6040)

+  16431, 16453, 16474, 16506, 16510, 16529
+
+* Slovenian translations for glibc messages have been contributed by the
+  Translation Project's Slovenian team of translators.
+
+* The public headers no longer use __unused nor __block.  This change is to
+  support compiling programs that are derived from BSD sources and use
+  __unused internally, and to support compiling with Clang's -fblock
+  extension which uses __block.
+
+* CVE-2012-4412 The strcoll implementation caches indices and rules for
+  large collation sequences to optimize multiple passes.  This cache
+  computation may overflow for large collation sequences and may cause a
+  stack or buffer overflow.  This is now fixed to use a slower algorithm
+  which does not use a cache if there is an integer overflow.
+
+* CVE-2012-4424 The strcoll implementation uses malloc to cache indices and
+  rules for large collation sequences to optimize multiple passes and falls
+  back to alloca if malloc fails, resulting in a possible stack overflow.
+  The implementation now falls back to an uncached collation sequence lookup
+  if malloc fails.
+
+* CVE-2013-4788 The pointer guard used for pointer mangling was not
+  initialized for static applications resulting in the security feature
+  being disabled. The pointer guard is now correctly initialized to a
+  random value for static applications. Existing static applications need
+  to be recompiled to take advantage of the fix (bug 15754).
+
+* CVE-2013-4237 The readdir_r function could write more than NAME_MAX bytes
+  to the d_name member of struct dirent, or omit the terminating NUL
+  character.  (Bugzilla #14699).
+
+* CVE-2013-4332 The pvalloc, valloc, memalign, posix_memalign and
+  aligned_alloc functions could allocate too few bytes or corrupt the
+  heap when passed very large allocation size values (Bugzilla #15855,
+  #15856, #15857).
+
+* CVE-2013-4458 Stack overflow in getaddrinfo with large number of results
+  for AF_INET6 has been fixed (Bugzilla #16072).
+
+* New locales: ak_GH, anp_IN, ar_SS, cmn_TW, hak_TW, lzh_TW, nan_TW, pap_AW,
+  pap_CW, quz_PE, the_NP.
+
+* Substantially revised locales: gd_GB, ht_HT
+
+* The LC_ADDRESS field was updated to support country_car for almost all
+  supported locales.
+
+* ISO 1427 definitions were updated.
+
+* ISO 3166 definitions were updated.
+
+* The localedef utility now supports --big-endian and --little-endian
+  command-line options to generate locales for a different system from that
+  for which the C library was built.
+
+* Binary locale files now only depend on the endianness of the system for
+  which they are generated and not on other properties of that system.  As a
+  consequence, binary files generated with new localedef may be incompatible
+  with old versions of the GNU C Library, and binary files generated with
+  old localedef may be incompatible with this version of the GNU C Library,
+  in the following circumstances:
+
+  + Locale files may be incompatible on m68k systems.
+
+  + Locale archive files (but not separate files for individual locales) may
+    be incompatible on systems where plain "char" is signed.
+
+* The configure option --disable-versioning has been removed.  Builds with
+  --disable-versioning had not worked for several years.
+
+* ISO 639 definitions were updated for Chiga (cgg) and Chinese (gan, hak, czh,
+  cjy, lzh, cmn, mnp, cdo, czo, cpx, wuu, hsn, yue).
+
+* SystemTap probes for malloc have been introduced.
+
+* SystemTap probes for slow multiple precision fallback paths of
+  transcendental functions have been introduced.
+
+* Support for powerpc64le has been added.
+
+* The soft-float powerpc port now supports e500 processors.
+
+* Support for STT_GNU_IFUNC symbols added for ppc32/power4+ and ppc64.
+
+* A new feature test macro _DEFAULT_SOURCE is available to enable the same
+  set of header declarations that are enabled by default, even when other
+  feature test macros or compiler options such as -std=c99 would otherwise
+  disable some of those declarations.
+
+* The _BSD_SOURCE feature test macro no longer enables BSD interfaces that
+  conflict with POSIX.  The libbsd-compat library (which was a dummy library
+  that did nothing) has also been removed.
+
+* Preliminary documentation about Multi-Thread, Async-Signal and
+  Async-Cancel Safety has been added.
+
+* Change of ABI data structures for s390 and s390x:
+  On s390 and s390x the size of struct ucontext and jmp_buf was increased to
+  allow for future hardware extensions. All library functions that accept or
+  return these structures were versioned in order to provide backwards
+  compatibility with existing code. However, not all cases can be handled
+  with interface versioning. If an application embeds either structure into
+  another structure and that structure is passed to another compilation unit
+  which expects the newer larger-sized object then any access to the new
+  fields will result in undefined behaviour. Similarly any access to fields
+  that were moved by the enlarging of the structures will cause undefined
+  behaviour. To fix the undefined behaviour all objects that are part of the
+  final in-memory image must agree on the size of structures, and this may
+  require recompilation.

+  15755, 15759.
+
+* CVE-2013-2207 Incorrectly granting access to another user's pseudo-terminal
+  has been fixed by disabling the use of pt_chown (Bugzilla #15755).
+  Distributions can re-enable building and using pt_chown via the new configure
+  option `--enable-pt_chown'.  Enabling the use of pt_chown carries with it
+  considerable security risks and should only be used if the distribution
+  understands and accepts the risks.
+
+* CVE-2013-0242 Buffer overrun in regexp matcher has been fixed (Bugzilla
+  #15078).
+
+* CVE-2013-1914 Stack overflow in getaddrinfo with many results has been
+  fixed (Bugzilla #15330).
+
+* Add support for calling C++11 thread_local object destructors on thread
+  and program exit.  This needs compiler support for offloading C++11
+  destructor calls to glibc.
+
+* Improved worst case performance of libm functions with double inputs and
+  output.
+
+* Support for priority inherited mutexes in pthread condition variables on
+  non-x86 architectures.
+
+* Port to Xilinx MicroBlaze contributed by David Holsgrove.
+
+* Optimized string functions for AArch64.  Implemented by Marcus Shawcroft.
+
+* Optimized string functions for ARM.  Implemented by Will Newton and
+  Richard Henderson.
+
+* Optimized libm functions for SPARC.  Implemented by David S. Miller.
+
+* Support for building more of ARM glibc as Thumb-2 code.  Implemented by
+  Richard Henderson.
+
+* Support for building most of MIPS glibc as MIPS16 code.  Implemented by
+  Chung-Lin Tang, Maciej W. Rozycki and Maxim Kuvyrkov.
+
+* Added a benchmark framework to track performance of functions in glibc.
+
+* New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
+  It is based on draft TS 18661 and currently enabled as a GNU extension.
+
+* On Linux, the clock function now uses the clock_gettime system call
+  for improved precision, rather than old times system call.
+
+* Added support for version-3 tz format files.  This is needed when using
+  the tz database release 2013e or later, and affects a few unusual cases --
+  currently only TZ='America/Godthab' for time stamps after 2037.
+
+* Added new API functions pthread_getattr_default_np and
+  pthread_setattr_default_np to get and set the default pthread
+  attributes of a process.
+
+* Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
+  This may improve lock scaling of existing programs on TSX capable systems.
+  When the --enable-lock-elision=yes parameter is specified at configure
+  time lock elision will be enabled by default for all PTHREAD_MUTEX_DEFAULT
+  mutexes.
+
+* Support added for AT_HWCAP2 (to coincide with Linux kernel 3.10
+  availability).  Implemented by Ryan S. Arnold.
+
+* Support added for POWER8 platform.  Implemented by Ryan S. Arnold.

+Version 2.17
+
+* The following bugs are resolved with this release:
+
+  1349, 3439, 3479, 3665, 5044, 5246, 5298, 5400, 6530, 6677, 6778, 6808,

+  14879, 14889, 14893, 14898, 14914.
+
+* Optimization of memcpy for MIPS.
+
+* CVE-2011-4609 svc_run() produces high cpu usage when accept fails with
+  EMFILE has been fixed (Bugzilla #14889).
+
+* The add-on ports collection is now distributed in the "ports" subdirectory
+  of the main GNU C Library distribution, rather than separately.
+
+* Port to ARM AArch64 contributed by Linaro.
+
+* Support for STT_GNU_IFUNC symbols added for s390 and s390x.
+  Optimized versions of memcpy, memset, and memcmp added for System z10 and
+  zEnterprise z196.
+  Implemented by Andreas Krebbel.
+
+* The new function secure_getenv allows secure access to the environment,
+  returning NULL if running in a SUID/SGID process.  This function replaces
+  the internal function __secure_getenv.
+
+* SystemTap static probes have been added into the dynamic linker.
+  Implemented by Gary Benson.
+
+* Optimizations of string functions strstr, strcasestr and memmem.
+  Implemented by Maxim Kuvyrkov.
+
+* The minimum Linux kernel version that this version of the GNU C Library
+  can be used with is 2.6.16.
+
+* Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for
+  powerpc POWER7.  Implemented by Will Schmidt.
+
+* New configure option --disable-nscd builds the C library such that it
+  never attempts to contact the Name Service Caching Daemon (nscd).
+  New configure option --disable-build-nscd avoids building nscd itself;
+  this is the default if --disable-nscd is used.
+
+* Improved support for cross-compilation, including cross-testing and
+  bootstrap builds without a previously built glibc.
+
+* Several testsuite tests are now able to test multiple IFUNC variants of an
+  interface, rather than just testing the one that would be chooen by
+  default.
+
+* New configure options --with-bugurl and --with-pkgversion, for
+  distributors to use to embed their bug-reporting and package version
+  information in --help and --version output.
+
+* The ttyname and ttyname_r functions on Linux now fall back to searching for
+  the tty file descriptor in /dev/pts or /dev if /proc is not available.  This
+  allows creation of chroots without the procfs mounted on /proc.
+
+* The `crypt' function now fails if passed salt bytes that violate the
+  specification for those values.  On Linux, the `crypt' function will
+  consult /proc/sys/crypto/fips_enabled to determine if "FIPS mode" is
+  enabled, and fail on encrypted strings using the MD5 or DES algorithm
+  when the mode is enabled.
+
+* The `clock_*' suite of functions (declared in <time.h>) is now available
+  directly in the main C library.  Previously it was necessary to link with
+  -lrt to use these functions.  This change has the effect that a
+  single-threaded program that uses a function such as `clock_gettime' (and
+  is not linked with -lrt) will no longer implicitly load the pthreads
+  library at runtime and so will not suffer the overheads associated with
+  multi-thread support in other code such as the C++ runtime library.
+
+* New locales: ayc_PE, doi_IN, ia_FR, mni_IN, nhn_MX, niu_NU, niu_NZ,
+  sat_IN, and szl_PL.
+

+  14277, 14278.
+
+* Support for the x32 ABI on x86-64 added.  The x32 target is selected by
+  configuring glibc with:
+	BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32'
+  Visit <http://sites.google.com/site/x32abi/> for more x32 ABI info.
+  Implemented by H.J. Lu.
+
+* ISO C11 support:
+
+  + define static_assert
+
+  + do not declare gets
+
+  + declare at_quick_exit and quick_exit also for ISO C11
+
+  + aligned_alloc.  NB: The code is deliberately allows the size parameter
+    to not be a multiple of the alignment.  This is a moronic requirement
+    in the standard but it is only a requirement on the caller, not the
+    implementation.
+
+  + timespec_get added
+
+  + uchar.h support added
+
+  + CMPLX, CMPLXF, CMPLXL added
+
+  Implemented by Ulrich Drepper.
+
+* Support for the IA-64 has been moved to ports.
+
+* Remove support for anything but ELF binary format
+
+* Checking versions of poll, ppoll added.
+  Implemented by Ulrich Drepper.
+
+* More generic and 64-bit performance optimizations to math functions.
+  Implemented by Ulrich Drepper.
+
+* New configure option --enable-obsolete-rpc makes the deprecated RPC
+  headers and functions available at compile time as they were before
+  version 2.14.  This option will be removed at some time in the future
+  after the TI-RPC library becomes fully sufficient for the needs of
+  existing applications.
+
+* Compatibility code for Linux kernel versions before 2.4 has been removed.
+  Note that glibc is not expected to work with any Linux kernel version
+  before 2.6.
+
+* New header <sys/auxv.h> and function getauxval allowing easy access to
+  the AT_* key-value pairs passed from the Linux kernel.  The header also
+  defines the HWCAP_* bits associated with the AT_HWCAP key.
+
+* New locales: mag_IN
+
+* New configure option --enable-systemtap builds SystemTap static probes
+  into libc for setjmp and longjmp and into libpthread for various operations.
+  So far the setjmp/longjmp probes and some of the libpthread probes are
+  provided only for i*86 and x86_64.
+  Implemented by Roland McGrath and Rayson Ho.
+
+* Optimized expf for x86-32 and x86-64.  Implemented by Liubov Dmitrieva.
+
+* More optimized functions for PowerPC.  Implemented by Adhemerval Zanella
+  and Will Schmidt.
+
+* More optimized functions for SPARC.  Implemented by David S. Miller.
+
+* Improved support for cross-compilation, especially bootstrap builds
+  without a previously built glibc.
+
+* Ports for the TILE-Gx and TILEPro families of processors.  Contributed by
+  Chris Metcalf from Tilera.
+
+* Support for the old ARM ABI has been removed from ports.  Only the EABI is
+  now supported for ARM processors.
+
+* The hard-float variant of the ARM EABI now uses /lib/ld-linux-armhf.so.3
+  as the name of the dynamic linker, to distinguish it from the
+  /lib/ld-linux.so.3 dynamic linker used for the base EABI.
+
+* Support for CRIS has been removed from ports.
+
+* A new class of installed header has been documented for low-level
+  platform-specific functionality.  PowerPC added the first instance with a
+  function to provide time base register access.  Contributed by Tulio
+  Magno Quites Machado Filho.
+
+* ix86 configurations now install header files that are consistent with
+  what x86-64 configurations install.  These same header files can be used
+  for -m32, -m64, or -mx32 builds.
+  Contributed by H.J. Lu.
+
+* Math library bug fixes.  A thorough audit of all open math library bugs was
+  conducted by Joseph Myers.  Significant progress was made on many math
+  library bugs resulting in more accurate exceptions and function results.
+  Many thanks to all those that contributed including Andreas Jaeger for his
+  patch review and work on the x87 trigonometric instruction issues.
+
+* Timezone data is no longer installed.  Timezone-related binaries and scripts
+  will continue to be installed.  Users should obtain their timezone data from
+  their distribution provider or from the tzdata package at
+  <ftp://munnari.oz.au/pub/>.

+  12795, 12811, 12813, 12814, 12841
+
+* The RPC implementation in libc is obsoleted.  Old programs keep working
+  but new programs cannot be linked with the routines in libc anymore.
+  Programs in need of RPC functionality must be linked against TI-RPC.
+  The TI-RPC implementation is IPv6 enabled and there are other benefits.
+
+  Visible changes of this change include (obviously) the inability to link
+  programs using RPC functions without referencing the TI-RPC library and the
+  removal of the RPC headers from the glibc headers.
+  Implemented by Ulrich Drepper.
+
+* New Linux interfaces: clock_adjtime, name_to_handle_at, open_by_handle_at,
+  syncfs, setns, sendmmsg
+
+* New locales: os_RU, bem_ZA, en_ZA, ff_SN, sw_KE, sw_TZ, lb_LU, wae_CH,
+  yue_HK, lij_IT, mhr_RU
+
+* New encodings: CP770, CP771, CP772, CP773, CP774
+
+* New program sotruss to trace calls through PLTs
+  Implemented by Ulrich Drepper.
+
+* The malloc hook implementation is marked deprecated and will be removed
+  from the default implementation in the next version.  The design never
+  worked ever since the introduction of threads.  Even programs which do
+  not create threads themselves can use multiple threads created internally.
+

+
+* The dynamic linker now recognizes supported ABI versions from the
+  EI_ABIVERSION field in the ELF header.
+  Implemented by Ulrich Drepper.
+
+* New NIS mode selector ADJUNCT_AS_SHADOW.  The passwd.adjunct.byname table
+  will not be used to fill in password fields in the passwd.byname replies.
+  Instead it is used to synthesize the shadow.byname table, should it be
+  missing.  This is a useful mode in some installations involving Solaris.

+* AVX support in x86-64 auditing support in ld.so.
+  Implemented by H.J. Lu.
+
+* STB_GNU_UNIQUE support added.
+  Implemented by Ulrich Drepper.
+
+* Implement second fallback mode for optimized DNS lookup for even more
+  broken environments.  If two requests from the same port are not
+  handled correctly close the socket and open a new one before sending
+  the second request.  The 'single-request-reopen' option in /etc/resolv.conf
+  can be used to select this mode right away, instead of rediscovering the
+  necessity is every process again.
+  Implemented by Ulrich Drepper.
+
+* New resolver flag RES_USE_DNSSEC to enable use of verified lookup.
+  Implemented by Adam Tkac.
+
+* Optimized iconv conversions for S390x.
+  Implemented by Andreas Krebbel.

+  NSS.  Implemented by Ulrich Drepper.
+
+* The malloc implementation can be compiled to be less memory efficient
+  but higher performing in multi-threaded programs.
+  Implemented by Ulrich Drepper.
+
+* New locales: nan_TW@latin, ks_IN
+
+* Faster strlen, strchr, strchrnul, strrchr, memchr, and rawmemchr for x86-64.
+  Implemented by Ulrich Drepper.
+
+* Extended printf hook support.  It is possible to use user-defined types
+  and extend existing format specifiers.
+  Implemented by Ulrich Drepper.
+
+* Handling for group shadow files has been added.
+  Implemented by Ulrich Drepper.
+
+* DNS IPv4-IPv6 parallel lookup now deals better with broken DNS
+  servers (the case, e.g., for some people using the built-in DNS
+  server in ADSL modems/routers).  There is a once-per-process timeout
+  in case of a broken server.  To avoid it, users can run nscd or put
+  'options single-request' in /etc/resolv.conf.
+  Implemented by Ulrich Drepper.

+  Implemented by Eric Blake.
+
+* New Linux interfaces: inotify_init1, dup3, epoll_create1, pipe2
+
+* Implement "e" option for popen to open file descriptor with the
+  close-on-exec flag set.  Implemented by Ulrich Drepper.
+
+* Implement "b" mode for fmemopen.  In this mode writes writes don't
+  implicitly add a NUL byte and seeks from the end of the buffer really
+  use the buffer end, not the string length as the basis.
+  Implemented by Ulrich Drepper.
+
+* Many functions, exported and internal, now atomically set the close-on-exec
+  flag when run on a sufficiently new kernel.  Implemented by Ulrich Drepper.
+
+* Sorting rules for some Indian languages (Kannada, Gurumukhi, Telugu,
+  Sinhala)
+  Implemented by Pravin Satpute.

+  Implemented by Harsha Jagasia and H.J. Lu.
+
+* Faster memcpy on x86.
+  Implemented by Ulrich Drepper.
+
+* ARG_MAX is not anymore constant on Linux.  Use sysconf(_SC_ARG_MAX).
+  Implemented by Ulrich Drepper.
+
+* Faster sqrt and sqrtf implemention for some PPC variants.
+  Implemented by Steven Munroe.

+  Implemented by Jakub Jelinek.
+
+* PPC optimizations to math and string functions.
+  Implemented by Steven Munroe.
+

+  4403, 4405, 4406, 4411, 4438, 4439, 4455, 4456, 4465, 4512, 4514, 4586,
+  4702, 4858
+
+* New Linux interfaces: epoll_pwait, sched_getcpu.
+
+* New generic interfaces: strerror_l.
+
+* nscd can now cache the services database.   Implemented by Ulrich Drepper.
+
+Version 2.5
+
+* The following bugs are resolved with this release:
+
+  39, 68, 192, 352, 388, 531, 935, 1006, 1201, 1203, 1386, 1782, 1783, 1784,

+  2349, 2376, 2386, 2389, 2415, 2418, 2420, 2423, 2450, 2451, 2466, 2472,
+  2473, 2477, 2498, 2499, 2501, 2502, 2505, 2507, 2508, 2509, 2517, 2526,
+  2569, 2571, 2592, 2611, 2625, 2632, 2644, 2662, 2680, 2683, 2684, 2693,
+  2695, 2703, 2734, 2751, 2764, 2766, 2775, 2792, 2821, 2823, 2832, 2841,

+  3225, 3251, 3252, 3253, 3273
+
+* For Linux, the sorting of addresses returned by getaddrinfo now also
+  handles rules 3, 4, and 7 from RFC 3484.  I.e., all rules are handled.
+  Implemented by Ulrich Drepper.
+
+* Allow system admin to configure getaddrinfo with the /etc/gai.conf file.
+  Implemented by Ulrich Drepper.
+
+* New Linux interfaces: splice, tee, sync_file_range, vmsplice.
+
+* New iconv module for MIK.  Contributed by Alexander Shopov.
+
+* For sites with broken group and/or passwd database, the auto-propagate
+  option of nscd can prevent creating ID lookup entries from the results
+  of a name lookup and vice versa.   This usually is no problem but some
+  site might have problems with the default behavior.
+  Implemented by Ulrich Drepper.
+
+* Iterating over entire database in NIS can be slow.  With the
+  SETENT_BATCH_READ option in /etc/default/nss a system admin can decide
+  to trade time for memory.  The entire database will be read at once.
+  Implemented by Ulrich Drepper.
+
+* The interfaces introduced in RFC 3542 have been implemented by
+  Ulrich Drepper.
+
+* Support for the new ELF hash table format was added by Ulrich Drepper.
+
+* Support for priority inheritance mutexes added by Jakub Jelinek and
+  Ulrich Drepper.
+
+* Support for priority protected mutexes added by Jakub Jelinek.
+
+* New locales: nr_ZA, pa_PK, ca_AD, ca_FR, ca_IT, el_CY, tr_CY, as_IN,
+  or_IN, csb_PL, fy_NL, sr_ME.
+
+Version 2.4
+
+* More overflow detection functions.
+
+* New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153,
+  IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba.
+
+  More converters for IBM803, IBM901, IBM902, IBM921, IBM1008, IBM1097,

+  IBM1145, IBM1146, IBM1147, IBM1148, IBM1149, IBM1166, IBM1167, IBM4517,
+  IBM4899, IBM4909, IBM4971, IBM5347, IBM9030, IBM9066, IBM9448, IBM12712,
+  IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed
+  by Masahide Washizawa.
+
+* It is now possible to install audit libraries for the dynamic linker using
+  LD_AUDIT.  Implemented by Ulrich Drepper.
+
+* The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no
+  longer supported.  The new NPTL implementation requires Linux 2.6 kernels.
+  For a libc and libpthread that works well on Linux 2.4 kernels, we
+  recommend using the stable 2.3 branch.
+
+* The new function open_wmemstream acts like open_memstream,
+  but uses a wchar_t wide character buffer.
+
+* The new function ppoll is an improved version of poll, similar to pselect.
+
+* New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat,
+  futimesat, faccessat, mkdirat, mkfifoat, mknodat,
+  renameat, unlinkat, linkat, symlinkat, readlinkat.
+
+* New Linux kernel system calls: unshare,
+  inotify_init, inotify_add_watch, inotify_rm_watch.
+
+* The euidaccess function is now also known by the alias eaccess,
+  for compatibility with some other systems.
+
+* Timezone data updated to 2006b version.
+
+Version 2.3.6
+
+* The following bugs are resolved with this release:

+
+  Visit <http://sources.redhat.com/bugzilla/> for the details of each bug.
+
+* As of this release, GCC 4 can be used to compile the C Library.
+
+* Timezone data updated to 2005m version.
+
+Version 2.3.5
+
+* The following bugs are resolved with this release:
+
+  284, 592, 602, 626, 633, 640, 650, 661, 671, 681, 693, 700, 710, 719,

+
+  Visit <http://sources.redhat.com/bugzilla/> for the details of each bug.
+
+Version 2.3.4
+
+* Support for RFC 3678.  Real implementations exist only for Linux so far.
+  Implemented by Ulrich Drepper.
+
+* nscd can now cache entries persistently.  Expiring entries are reloaded.
+  For speedups the cache can be shared in memory with client processes.
+  Implemented by Ulrich Drepper.
+
+* nscd can now perform SELinux checks.
+  Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>.
+
+* getaddrinfo queries are now cached.  Canonical name lookup is performed
+  efficiently.
+  Implemented by Ulrich Drepper.
+
+* The nothrow function attribute is used when headers are used by gcc when
+  compiling C code.  This can avoid significant amounts of exception
+  handling data.
+
+* The malloc functions perform more error checking and are stricter when
+  it comes to reacting on errors.  The default action is to terminate
+  the process after showing an error message.  Implemented by Ulrich Drepper.
+
+* Reverse lookups of IPv6 addresses does not use bit string or .ip6.int
+  lookups anymore unless explicitly requested.  Implemented by Ulrich Drepper.
+
+* Namespaces in ld.so are implemented.  DSOs can be loaded in separate
+  namespaces using the new function dlmopen().  This feature is of course,
+  like most other dynamic loading functionality, not available in statically
+  linked applications.  Implemented by Ulrich Drepper.
+
+* Low-overhead boundary checking variants of string and some stdio functions
+  were added.  These are to be used in conjunction with a gcc patch by
+  Jakub Jelinek which adds calls to these functions if possible.
+  Implemented by Jakub Jelinek and Ulrich Drepper.
+
+* Old code for several operating systems and machine architectures that
+  have not been in working condition in a long time have been removed from
+  the main source tree maintained by the GNU C Library's maintainers.
+  These files are now reside in the separate `ports' source module
+  that is usable as an add-on when building the library.
+
+Version 2.3.3
+
+* New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to
+  interrogate the dynamic linker, compatible with the Solaris interface.
+
+* ELF thread-local storage support (TLS) now works on PowerPC and PowerPC64;
+  implemented by Paul Mackerras, Steven Munroe, and Roland McGrath.
+
+* getifaddrs now uses the netlink interface on Linux to get its information.
+  Implemented by Thorsten Kukuk.
+
+* getaddrinfo now implements AI_V4MAPPED, AI_ALL, and AI_ADDRCONF.
+  Implemented by Ulrich Drepper.
+
+* support for non-executable stacks on x86 has been added.  Changes mostly
+  by Roland McGrath.
+
+* regex is now much faster for multibyte locales.  Changes by Jakub Jelinek
+  and Ulrich Drepper.
+
+* getaddrinfo now performs destination address selection according to
+  RFC 3484.
+
+Version 2.3.2
+
+* Thread-safe interfaces for many functions that access locale data
+  were added in version 2.3, but these features were omitted from NEWS.
+  Many functions have variants with an `_l' suffix that take a `locale_t'
+  object as a parameter rather than consulting the current locale.
+  The new functions `newlocale', `duplocale', and `freelocale' in <locale.h>
+  create and maintain `locale_t' objects.  Additionally, the new function
+  `uselocale' sets "the current locale" (as used by functions not so
+  parameterized) set for an individual thread.  These features were added
+  in version 2.3, implemented by Ulrich Drepper and Roland McGrath.
+
+* The functions getresuid, getresgid, setresuid, and setresgid, which
+  have long been available on Linux, are now declared in <unistd.h>
+  and are now also available on the Hurd.
+
+* ELF thread-local storage support (TLS) now works on x86-64.
+
+* The new dynamic string token $LIB is expanded in shared library names.
+  This normally expands to lib, but on some 64-bit platforms to lib64 instead.
+
+* Aldy Hernandez contributed complete software floating point support for
+  PowerPC machines with no FPU.
+
+* fexecve is implemented on Linux.
+
+* The `btowc' function should work at least twice as fast due to
+  specialized callbacks in the iconv modules.  Implemented by Bruno Haible.
+
+* With approriate thread add-ons cancelable functions are now implemented
+  in libc.so as well.  No need to call the function in libpthread.  This
+  change allowed to finally disable the incorrect and expensive handling
+  of weak definition in ld.so.
+
+* Yet more PLT entries in libc.so have been removed.  We finally arrived
+  at the bare minimum.  Startup times improved appropriately.
+
+* Support for the new Linux/x86 system call interface was added.  The
+  AT_SYSINFO auxiliary vector entry is recognized and handled.
+
+Version 2.3
+
+* Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164
+  charsets.
+
+* iconv (the program and the interface) now accepts empty names (excluding
+  options like //TRANSLIT) to mean "use charset of current locale".
+
+* localedef can now transliterate characters in strings which are not in
+  the provided charmap.  The information from the input locale is used.
+
+* Prelinking support was added for ELF targets.  This requires additional
+  tools and recent versions of the GNU binutils.  Contributed by Jakub Jelinek.
+
+* Read-only stdio streams now use mmap to speed up operation by eliminating
+  copying and buffer underflows.  To use add 'm' to the mode string of
+  the fopen/fdopen/freopen call.  Implemented by Ulrich Drepper.
+
+* The malloc functions were completely rewritten by Wolfram Gloger based
+  on Doug Lea's malloc-2.7.0.c.
+
+* Isamu Hasegawa contributed a completely new and POSIX-conformant
+  implementation of regex.
+
+* Bruno Haible upgraded the iconv and locale implementation to support
+  Unicode 3.2.
+
+* Contents of the LC_* and LANG environment variables in the CEN style are
+  not recognized anymore.   It never was used.  Change by Ulrich Drepper.
+
+* The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF
+  thread-local storage (TLS) ABI on some platforms.
+  Changes by Ulrich Drepper.  SH support by Kaz Kojima.
+
+* Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213,
+  EUC-JISX0213, and TSCII.
+
+* New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs':
+  BSD-compatible interface for getting all network interface addresses.
+  Implementation for IPv4 by Roland McGrath.
+
+* Loading of locale data is faster due to the introduction of a locale
+  archive.  Implemented by Roland McGrath and Ulrich Drepper.
+
+* Startup times are significantly reduced by not using exported functions
+  inside the library itself.  Changes by Jakub Jelinek, Roland McGrath,
+  and Ulrich Drepper.
+
+* Steven Munroe contributed a port to PowerPC64/Linux.
+
+Version 2.2.6
+
+* The Hurd now uses the GNU libio implementation of stdio rather than the
+  old GNU stdio implementation, and uses a new ABI (libc.so.0.3).
+
+* The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file
+  with the same behavior as the Linux system call of the same name.
+
+Version 2.2.5
+
+* Stephen Moshier implemented log2, log10, powl and cbrtl for the
+  128-bit long double format.
+
+* Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160,
+  IBM1161, and IBM1162 charsets.
+
+* Andreas Jaeger contributed a port to x86-64/Linux.
+
+* Peter Bruin contributed a port to PowerPC/Hurd.
+
+* libc functions using I/O streams now can handle wide-oriented streams
+  as well.
+
+* optimizations in the dynamic linker.  Binaries created by recent binutils
+  versions start up quicker due to reduced time spent on relocations.
+
+* Support for use of gcc3 added by Jakub Jelinek and HJ Lu.
+
+Version 2.2.4
+
+* Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh,
+  asinh, atanh, j0 for the 128-bit long double format.
+
+* Bruno Haible updated all the code handling Unicode in some form to
+  support Unicode 3.1.
+
+* Speed of regex for single-byte locales is back to previous levels.
+  Patch by Isamu Hasegawa.
+
+* Alpha, SPARC, and IA-64 now also using floating stacks.
+
+* Startup time of internationalized applications greatly improved through
+  iconv cache.  Use iconvconfig to generate the cache file.
+  Contributed by Ulrich Drepper.
+
+* The IA-64 specific part of ld.so was rewritten to eliminate some pretty
+  severe performance problems.  Patch by David Mosberger.
+
+* The Hurd port got a lot more functionality like AIO, various stdio
+  extensions, etc.  Mainly done by Roland McGrath.
+
+* mtrace can now lookup symbols in shared libraries.
+
+Version 2.2.3
+
+* Intel's IA-64 math library is largely integrated.  It provides fast and
+  accurate implementatations for most basic and standard math functions
+  in float, double, and long double format.
+
+* Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc,
+  and asin for the 96-bit long double format and asin, log, tan for the
+  128-bit long double format.
+
+* The beginning of a last-bit accurate math library by IBM Haifa were added.
+  The basic double functions exist today.  Contributed by Abraham Ziv
+  <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis
+  <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>.
+
+* An asynchronous name lookup library was added.  The interface is designed
+  after POSIX AIO.  The proposal was circulated beforehand to get comments.
+  No negative ones came in.  Implemented by Ulrich Drepper.
+
+* Port to S390/64bit contributed by Martin Schwidefsky
+  <schwidefsky@de.ibm.com>.
+
+* David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
+  of functions for Linux/IA-64.
+
+* The RPC code is now thread safe.  Threads can now use the same service
+  of different services at the same time.  Patch by Eric Norum
+  <eric.norum@usask.ca> with some help by Ulrich Drepper.
+
+* Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext
+  family of functions for Linux/S390.
+
+* Ulrich Drepper <drepper@redhat.com> implemented the setcontext family
+  of functions for Linux/x86.
+
+* Port to Linux/CRIS contributed by Axis Communications.
+
+Version 2.2.2
+
+* Lots of headers were cleaned up.  Using the tool in the conform/ subdir
+  we can now check for namespace violations and missing declarations.  The
+  result is that almost all headers are now Unix-compliant (as defined in
+  the upcoming XPG6).  The negative side is that some programs might need
+  corrections, too, if they depend on the incorrect form of the headers in
+  previous versions which defined too many symbols and included too many
+  other headers.
+
+* regex now handles multibyte character sets correctly.
+  Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
+
+* iconv (the program) does now conform to the upcoming XPG6 and handles
+  charmaps.  Instead of the charset names the path of charmaps can be
+  provided and the conversion happens based on this data.
+  Contributed by Ulrich Drepper.
+
+* The locale program now provides detailed information about the installed
+  locales.  While
+
+    locale -a
+
+  only lists the names of the supported locales
+
+    locale -a --verbose
+
+  provides details such as country, language, and codeset name.
+  Contributed by Ulrich Drepper.
+
+Version 2.2.1
+
+* The gencat program now parses the input file according to the charset
+  selected by the LC_CTYPE category.  This is important for stateful
+  character sets.  To make generating catalogs easier there is a way
+  to overwrite the charset selected by the locale: before the first
+  message or $ quote line the catalog can contain a line like
+
+    $ codeset=ISO-8859-2
+
+  to select the charset (ISO-8859-2 in this case).
+
+  Implemented by Shinya Hanataka and Ulrich Drepper.
+
+* New codeset conversion modules: IBM-922  (Estonia PC codeset),
+  IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset).
+  Contributed by Masahide Washizawa <washi@jp.ibm.com>.
+
+* Optimized string functions for Alpha ev6 and ev67 by Richard Henderson
+  <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>.
+
+* The LANGUAGE environment variable is now ignored unless the locale is
+  changed from the default "C" locale.
+
+* The usual bug fixes.
+
+Version 2.2
+
+* Greg McGary added runtime support for bounds checking using gcc's
+  new -fbounded-pointers option.  ix86 target is complete.  PowerPC
+  is in progress.
+
+* Thorsten Kukuk added secure mode support to nscd.
+
+* The Berkeley db libraries have been removed.
+
+  Related, the nss_db module is now in a separate package since it
+  obviously requires a database library being available.
+
+* Wide character I/O streams implemented by Ulrich Drepper.
+
+* Functions from the extended socket API added by Ulrich Drepper.
+
+* Functions feenableexcept and fedisableexcept to control the
+  behaviour of individual exceptions have been added by Andreas Jaeger.
+
+* ldconfig program added by Andreas Jaeger and Jakub Jelinek.
+
+* The resolver code has been updated from bind 8.2.3-T5B which supports
+  threads.  The integration was done by Andreas Jaeger, Adam D. Bradley,
+  and Mark Kettenis.
+
+  This change could in some situations effect backward compatibility.  Since
+  now `_res' is a thread-local instead of a global variable, modifying it
+  in one thread does not have any effect in other threads.
+
+  The resolver library was also extended to allow IPv6 as the transport
+  protocol for the requests.  This work was done by Stig Venaas.
+
+* Compatibility code for K&R C compilers has been removed from the
+  header files.  A ISO C compiler is needed to use the library
+  (conforming to either C89 or C99 standard).
+
+* Complete rewrite of the localedef program to support multibyte character
+  sets.  Implement handling of ISO 14651 and ISO 14652.  Rewrite strcoll,
+  strxfrm, wcscoll, and wcsxfrm functions.  Make isw*() functions work.
+  Implemented by Ulrich Drepper.
+
+  Bruno Haible significantly improved the generation and use of the data
+  structures for the wide character tables.
+
+* Plural handling in gettext implemented by Ulrich Drepper.
+
+* The utmp daemon has been removed.
+
+* The port to MIPS-Linux has been finished by Andreas Jaeger.
+
+* A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima
+  and Yutaka Niibe.
+
+* POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper.
+
+* POSIX barriers implemented by Kaz Kylheku.
+
+* POSIX spawn function family implemented by Ulrich Drepper.
+
+* POSIX spinlocks are now available.
+
+* Timed wait functions for mutex, rwlock, and semaphores are implemented.
+
+* the configure option --enable-kernel=X.Y.Z allows to strip out
+  compatibility for kernel versions before X.Y.Z.  This is currently only
+  implemented for Linux.
+
+* the sockaddr_in6 structure changed.  The IPv6 working group added a new
+  field sin6_scope_id.  This means that all programs using IPv6 should be
+  recompiled.  Don't expect binary compatibility with previous glibc
+  versions.
+
+* various conversion modules for IBM character sets contributed by
+  Masahide Washizawa.
+
+* IA-64 port by Jes Sorensen and HJ Lu.
+
+Version 2.1.3
+
+* bug fixes
+
+
+Version 2.1.2
+
+* bug fixes
+
+
+Version 2.1.1
+
+* New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.
+
+* New xdr functions are added; some rpc functions are now 64bit clean.
+
+* Fixed a number of bugs and memory leaks (especially in NIS+ code).
+
+* Fixed known incompatibilities with glibc 2.0.
+
+* New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx.
+
+* Optimized a number of functions (especially the ELF dynamic loader).
+
+* Update timezone data files.
+
+* lots of charmaps corrections
+
+* some new locale definitions and charmaps
+
+
+Version 2.1
+
+* Richard Henderson corrected size of struct timeval on Linux/Alpha to
+  conform to POSIX member type requirements.  Symbol versions have been
+  adjusted as needed within the library, and for direct use by applications,
+  but there is potential for problems if third-party libraries use
+  struct timeval as part of their interface.  This does not present
+  a problem for X and other "essential" system libraries.
+
+* An additional locale model to support C++ Standard Library locale
+  model and probably more was implemented by Ulrich Drepper.
+
+* Eric Youngdale and Ulrich Drepper implemented versioning of objects on
+  symbol level.
+
+* Miles Bader provided the `argp' function family to support hierachical
+  command line argument parsing, layered on top of getopt.
+
+* strtod accepts new hexadecimal floating-point format from ISO C 9X.
+
+* printf has two new specifiers %a and %A to print hexadecimal flaoting-point
+  numbers.
+
+* scanf recognizes the %a and %A format for scanning floating point numbers.
+
+* the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
+  information and interfaces for the available integer types.
+
+* about 130 new math functions were added to implement the ISO C9x math
+  library.
+
+* the new header <complex.h> contains definitions of the complex math
+  functions from ISO C 9X.
+
+* the new header <tgmath.h> defines generic macros to use complex or
+  real valued functions.
+
+* Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
+
+* Andreas Jaeger provided a test suite for the math library.
+
+* Mark Kettenis implemented the utmpx interface and an utmp daemon.
+
+* Ulrich Drepper added character set conversion functions (iconv).
+
+* Optimized string functions have been added.
+
+* The localedata addon is now part of glibc.
+
+* An implementation of profiling shared libraries was added by Ulrich Drepper.
+
+* Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
+  daemon for NSS (nscd).
+
+  Missing a better place here are some numbers on improvements.  Under
+  Linux 2.1.125 un-tar-ing the kernel sources takes
+
+				  user	system	   wall
+
+    using local files		12.19s	 6.88s	 22.91s
+
+    using NIS			13.92s	 8.91s	 26.34s
+
+    using NIS & nscd		10.37s	 7.34s	 25.30s
+
+    using NIS+			27.57s	30.37s  640.46s
+
+    using NIS+ & nscd           10.25s   7.83s   26.51s
+
+    using NIS & old nscd [1]	13.83s	 8.32s	 29.60s
+
+  Keep in mind that non-namelookup related operations dominate above times.
+  It was just a common complain that using NIS+ unpacking the kernel is
+  horribly slow.
+
+  [1] The old nscd implementation is not available anymore since it was
+  distributed with glibc up to version 2.0.98 and thus is now replaced.
+
+* Tim Waugh provided an implementation of the POSIX.2 wordexp function family.
+
+* Mark Kettenis provided a Hesiod NSS module.
+
+* The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN
+  and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper).
+
+* rcmd can now handle netgroups (Dick Streefland).
+
+* A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott
+  Bambrough.
+
+* Support for the IPv6 protocol has been added to the socket API, as per the
+  latest draft standards.
+
+* Support for Linux 2.2 has been added.
+
+* Interface changes relative to the latest 2.0.x release:

+
+Version 2.0.1
+
+* fixed lots of header problems (especially Linux/GNU specific)
+
+* dynamic loader preserves all registers
+
+* Roland McGrath provided support for handling of auxiliary objects in
+  the ELF dynamic loader.
+
+* support for parallel builds is improved
+
+Version 2.0
+
+* GNU extensions are no longer declared by default.  To enable them you
+  must define the macro `_GNU_SOURCE' in your program or compile with
+  `-D_GNU_SOURCE'.
+
+* The library has changed from using GNU ld symbol aliases to using weak
+  symbols where available.  The ELF object file format supports weak
+  symbols; GNU ld also supports weak symbols in the a.out format.  (There
+  is also now support for other GNU ld extensions in ELF.  Use the
+  `--with-elf' option to configure to indicate you have ELF, and
+  `--with-gnu-ld' if using GNU ld.)  This change resulted in the deletion
+  of many files which contained only symbol aliases, reducing the size of
+  the source and the compiled library; many other files were renamed to
+  less cryptic names previously occupied by the symbol alias files.
+  There is a new header file <elf.h> for programs which operate on
+  files in the ELF format.
+
+* Converted to Autoconf version 2, so `configure' has more options.
+  Run `configure --help' to see the details.
+
+* The library can now be configured to build profiling, highly-optimized
+  (but undebuggable), and/or shared libraries (ELF with GNU ld only).  The
+  `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
+  `configure' enable building these extra libraries.  The shared library is
+  built by default when using both ELF and GNU ld.  When shared libraries
+  are enabled, the new library `-ldl' is available for arbitrary run-time
+  loading of shared objects; its interface is defined in <dlfcn.h>.  The
+  new header file <link.h> gives access to the internals of the run-time
+  dynamic linker, `ld.so'.  The shell script `ldd' is similar to the
+  application of same name on other systems and it provides information
+  about dynamically linked binaries.
+
+* The C library now provides the run-time support code for profiling
+  executables compiled with `-pg'.  Programs can control the profiling code
+  through the interface in <sys/gmon.h>.  The `gmon.out' files written by
+  the GNU C library can be read only by GNU `gprof' (from GNU binutils);
+  the support for this file format was contributed by David Mosberger-Tang.
+
+* The math code has been replaced with a math library based on fdlibm from
+  Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
+  Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
+  functions.  The math functions now reside in a separate library,  so
+  programs using them will need to use `-lm' their linking commands.
+
+* John C. Bowman contributed optimized ix87 assembler inline functions.
+
+* Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
+  mechanism similar to that found in Solaris 2.  This is now used for the
+  group, passwd, hosts, networks, services, protocols, rpc, ethers,
+  shadow, netgroup, publickey, and alias databases.  The `nsswitch.conf'
+  file controls what services are used for each individual database.  This
+  works by loading shared libraries with names specified in `nsswitch.conf',
+  so service modules can be changed or added at any time without even
+  relinking any program.  Currently there are the file, db, and NIS based
+  NSS services available.
+
+* The new functions `strtoq' and `strtouq' parse integer values from
+  strings, like `strtol' and `strtoul', but they return `long long int' and
+  `unsigned long long int' values, respectively (64-bit quantities).
+
+* The new functions `strtof' and `strtold' parse floating-point values from
+  strings, like `strtod', but they return `float' and `long double' values,
+  respectively (on some machines `double' and `long double' are the same).
+
+* Ulrich Drepper has contributed new implementations of the floating-point
+  printing and reading code used in the `printf' family of functions and
+  `strtod', `strtof', and `strtold'.  These new functions are perfectly
+  accurate, and much faster than the old ones.
+
+* The implementation of the POSIX locale model was completely rewritten by
+  Ulrich Drepper.  This includes the new programs `localedef' and `locale'
+  to compile the POSIX locale definition.
+
+* The former dummy implementations of the strcoll and strxfrm function are
+  now replaced by fully functional code contributed by Ulrich Drepper.  The
+  collation information comes from the POSIX locale definitions.
+
+* The new header <langinfo.h> defines an interface for accessing
+  various locale-dependent data (using the locale chosen with `setlocale').
+
+* Ulrich Drepper has contributed a new suite of functions for operation on
+  wide-character and multibyte-character strings, in <wchar.h>;
+  and classification and case conversion of wide characters, in <wctype.h>.
+  These new functions are conforming to the ISO C, Amendement 1 specification.
+
+* There is now a second implementation of the standard I/O library available.
+  It comes from GNU libg++ as was written by Per Bothner, heavily modified
+  by Hongjiu Lu and made thread safe by Ulrich Drepper.
+
+* You can now use positional parameter specifications in format strings
+  for the `printf' and `scanf' families of functions.  For example,
+  `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
+  ``Number 6, Mr Jones''.  This is mainly useful when providing different
+  format strings for different languages, whose grammars may dictate
+  different orderings of the values being printed.  To support this
+  feature, the interface for `register_printf_handler' has changed; see
+  the header file <printf.h> for details.
+
+* The `printf' and `scanf' families of functions now understand a new
+  formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
+  to group numbers as indicated by the locale; for `scanf' and friends, this
+  says to accept as valid only a number with all the proper grouping
+  separators in the right places.  In the default "C" locale, numbers are
+  not grouped; but locales for specific countries will define the usual
+  conventions (i.e. separate thousands with `,' in the US locale).
+
+* The pgrp functions have been regularized, slightly incompatibly but much
+  less confusingly.  The core functions are now `getpgid' and `setpgid',
+  which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
+  argument) and BSD `setpgrp' (identical to `setpgid') functions are
+  provided for compatibility.  There is no longer an incompatible `getpgrp'
+  with an argument declared under _BSD_SOURCE; no BSD code uses it.
+
+* The new header file <fts.h> and suite of functions simplify programs that
+  operate on directory trees.  This code comes from 4.4 BSD.
+
+* The resolver code has been updated from the BIND 4.9.5-P1 release.
+  Parts of the code were heavily modified by Ulrich Drepper to fit in the
+  NSS scheme used in glibc.
+
+* There is a new malloc debugging hook `__memalign_hook'.
+
+* There are new typedefs `ushort' for `unsigned short int' and `uint' for
+  `unsigned int' in <sys/types.h>.  These are for compatibility only and
+  their use is discouraged.
+
+* The `-lmcheck' library to enable standard malloc debugging hooks is now
+  done differently, so that it works even without GNU ld.
+
+* New function `euidaccess' checks allowed access to a file like `access',
+  but using the effective IDs instead of the real IDs.
+
+* The time zone data files have been updated for the latest and greatest
+  local time conventions of the countries of the world.
+
+* The new function `dirfd' extracts the file descriptor used by a DIR stream;
+  see <dirent.h>.
+
+* The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
+  for formatting floating-point numbers.  They are provided only for
+  compatibility; new programs should use `sprintf' instead.  There are
+  also equivalent function for the `long double' floating-point type and
+  all functions also exist in a reentrant form.
+
+* The new auxiliary library `-lutil' from 4.4 BSD contains various
+  functions for maintaining the login-record files (primarily of use to
+  system programs such as `login'), and convenient functions for
+  allocating and initializing a pseudo-terminal (pty) device.
+
+* Ulrich Drepper has contributed new support for System V style
+  shared memory and IPC on systems that support it.
+
+* Ulrich Drepper has contributed several miscellaneous new functions found
+  in System V: The `hsearch' family of functions provide an effective
+  implementation of hash tables; `a64l' and `l64a' provide a very simple
+  binary to ASCII mapping; `drand48' and friends provide a 48-bit random
+  number generator.
+
+* Ulrich Drepper has contributed new reentrant counterparts for the
+  `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
+
+* Ulrich Drepper has contributed new, highly-optimized versions of several
+  string functions for the i486/Pentium family of processors.
+
+* Ulrich Drepper has updated the Linux-specific code, based largely
+  on work done in Hongjiu Lu's version of GNU libc for Linux.
+  The GNU library now supports Linux versions 2.0.10 and later,
+  using the ELF object file format (i[3456]86-*-linux).
+
+* Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
+
+* David Mosberger-Tang and Richard Henderson have ported the C library
+  to Linux/Alpha (alpha-*-linux).  Richard Henderson contributed the
+  dynamic linking support for ELF/Alpha.
+
+* Richard Henderson contributed several Alpha optimized assembler function
+  for arithmetic and string handling.
+
+* Ulrich Drepper has contributed a new set of message catalog functions to
+  support multiple languages using the <libintl.h> interface, for use with
+  his new package GNU gettext.  Translation volunteers have contributed
+  catalogs of the library's messages in Spanish, German, and Korean.
+
+* For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
+  program and the `catgets' function for reading the catalog files it
+  creates.  (The <libintl.h> interface is preferred; we include the
+  <nl_types.h> interface using `catgets' only for source compatibility with
+  programs already written to use it.)
+
+* New header file <values.h> gives SVID-compatible names for <limits.h>
+  constants.
+
+* Various new macros, declarations, and small header files for compatibility
+  with 4.4 BSD.
+
+* New function `group_member' is a convenient way to check if a process has
+  a given effective group ID.
+
+* When using GCC 2.7 and later, the socket functions are now declared in a
+  special way so that passing an argument of type `struct sockaddr_in *',
+  `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
+  `struct sockaddr *' type, does not generate a type-clash warning.
+
+* New function `error' declared in header file <error.h> is a convenient
+  function for printing error messages and optionally exiting; this is the
+  canonical function used in GNU programs.  The new functions `err', `warn',
+  and friends in header file <err.h> are the canonical 4.4 BSD interface for
+  doing the same thing.
+
+* The <glob.h> interface has several new flags from 4.4 BSD that extend the
+  POSIX.2 `glob' function to do ~ and {...} expansion.
+
+* New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
+  `clearenv' which is used in POSIX.9 is also available.
+
+* New function `getsid' returns session ID number on systems that support it.
+
+* We have incorporated the 4.4 BSD `db' library (version 1.85).  New header
+  files <db.h> and <mpool.h> provide a rich set of functions for several
+  types of simple databases stored in memory and in files, and <ndbm.h> is
+  an old `ndbm'-compatible interface using the `db' functions.  Link with
+  `-ldb' to get these functions.
+
+* New macro `strdupa' copies a string like `strdup', but uses local stack
+  space from `alloca' instead of dynamic heap space from `malloc'.
+
+* New function `strnlen' is like `strlen' but searches only a given maximum
+  number of characters for the null terminator.  `stpncpy', `strndup' and
+  `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
+  function.
+
+* New function `statfs' in header <sys/statfs.h>.
+
+* The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
+  provide convenient functions for operating on blocks of null-terminated
+  strings.
+
+* A new suite of functions in <utmp.h> handle all the details of reading
+  and writing the utmp file.
+
+* An implementation of the NIS/YP(tm) based NSS service was contributed by
+  Thorsten Kukuk.
+
+* Paul Eggert and Ulrich Drepper modified the `strftime' function to be
+  completely POSIX compliant and also implemented the extended functionality
+  to handle alternate digit representation and alternate era date formats.
+
+* Ulrich Drepper provided an implementation of the `strptime' function
+  defined in XPG4.2 which transforms a string into a `struct tm' value.
+
+* Paul Eggert provided the tzselect shell script as part of the timezone
+  code.  The shell script makes it easy to select the correct timezone
+  specification.
+
+* The implementation of the malloc family of functions is completely replaced
+  by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
+  The implementation uses the mmap function (if available) and it is
+  optimized for the use in multi threaded programs.
+
+* Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
+  functions.  This new functionality is usable by specifying a special
+  salt string and it is compatible with implementation on *BSD systems.
+
+* Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
+  `getsubopt' to handle second level command line options, `bsd_signal'
+  to access BSD style `signal' functionality, the obsolete `regexp' style
+  expression matcher.
+
+* the `lchown' function is available on system which support this
+  functionality.
+
+* The implementation of the shadow password handling function was contributed
+  by Ulrich Drepper.
+
+* David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
+
+* POSIX.1g support was added.  The <sys/select.h> header is available,
+  `isfdtype' and `pselect' are implemented.  Craig Metz contributed an
+  implementation of `getaddrinfo'.
+
+Version 1.09
+
+* For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
+
+* New header file <fstab.h> and new functions `getfsspec', `getfsent' and
+  friends, for parsing /etc/fstab.  This code comes from 4.4 BSD.
+
+* The new function `daemon' from 4.4 BSD is useful for server programs that
+  want to put themselves in the background.
+
+* Joel Sherrill has contributed support for several standalone boards that
+  run without an operating system.
+
+* `printf', `scanf' and friends now accept a `q' type modifier for long
+  long int as well as `ll'.  Formats using these might be `%qu' or `%lld'.
+
+* All of the code taken from BSD (notably most of the math and networking
+  routines) has been updated from the BSD 4.4-Lite release.
+
+* The resolver code has been updated from the BIND-4.9.3-BETA9 release.
+
+* The new functions `getdomainname' and `setdomainname' fetch or change the
+  YP/NIS domain name.  These are system calls which exist on systems which
+  have YP (aka NIS).
+
+* The time zone data files have been updated for the latest international
+  conventions.
+
+* The SunRPC programs `portmap' and `rpcinfo' are now installed in
+  $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
+
+Version 1.08
+
+* The C library now includes support for Sun RPC, from Sun's free
+  RPCSRC-4.0 distribution.  The `portmap', `rpcinfo', and `rpcgen' programs
+  are included.  (There is still no support for YP.)
+
+* Tom Quinn has contributed a port of the C library to SGI machines running
+  Irix 4 (mips-sgi-irix4).
+
+* The new `lockf' function is a simplified interface to the locking
+  facilities of `fcntl', included for compatibility.
+
+* New time functions `timegm', `timelocal', and `dysize' for compatibility.
+
+* New header file <sys/timeb.h> and new function `ftime' for compatibility.
+
+* New header files <poll.h> and <sys/poll.h> and new function `poll' for
+  compatibility.
+
+* The error message printed by `assert' for a failed assertion now includes
+  the name of the program (if using GNU ld) and the name of the calling
+  function (with versions of GCC that support this).
+
+* The `psignal' function is now declared in <signal.h>, not <stdio.h>.
+
+* The library now includes the <sys/mman.h> header file and memory
+  management functions `mmap', `munmap', `mprotect', `msync', and
+  `madvise', on systems that support those facilities.
+
+* The interface for `mcheck' has changed slightly: the function called to
+  abort the program when an allocation inconsistency is detected now takes
+  an argument that indicates the type of failure.  The new function
+  `mprobe' lets you request a consistency check for a particular block at
+  any time (checks are normally done only when you call `free' or `realloc'
+  on a block).
+
+* It is now possible to easily cross-compile the C library, building on one
+  system a library to run on another machine and/or operating system.  All
+  you need to do is set the variable `HOST_CC' in `configparms' to the
+  native compiler for programs to run on the machine you are building on (a
+  few generator programs are used on Unix systems); set `CC' to the
+  cross-compiler.
+
+* The new function `fexecve' (only implemented on the GNU system) executes
+  a program file given a file descriptor already open on the file.
+
+Version 1.07
+
+* Brendan Kehoe has contributed most of a port to the DEC Alpha
+  running OSF/1 (alpha-dec-osf1).  He says it is 75% complete.
+
+* You can set the variable `libprefix' in `configparms' to specify a prefix
+  to be prepended to installed library files; this makes it easy to install
+  the GNU C library to be linked as `-lgnuc' or whatever.
+
+* The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
+  copies a limited number of characters from a string, and returns the
+  address of the last character written.
+
+* You no longer need to check for whether the installed `stddef.h' is
+  compatible with the GNU C library.  configure now checks for you.
+
+* You can now define a per-stream `fileno' function to convert the
+  stream's cookie into an integral file descriptor.
+
+* ``malloc (0)'' no longer returns a null pointer.  Instead, it
+  allocates zero bytes of storage, and returns a unique pointer which
+  you can pass to `realloc' or `free'.  The behavior is undefined if
+  you dereference this pointer.
+
+* The C library now runs on Sony NEWS m68k machines running either
+  NewsOS 3 or NewsOS 4.
+
+* The new `syscall' function is a system-dependent primitive function
+  for invoking system calls.  It has the canonical behavior on Unix
+  systems, including unreliable return values for some calls (such as
+  `pipe', `fork' and `getppid').
+
+* The error code `EWOULDBLOCK' is now obsolete; it is always defined
+  to `EAGAIN', which is the preferred name.  On systems whose kernels
+  use two distinct codes, the C library now translates EWOULDBLOCK to
+  EAGAIN in every system call function.
+
+Version 1.06
+
+* The GNU C Library Reference Manual is now distributed with the library.
+  `make dvi' will produce a DVI file of the printed manual.
+  `make info' will produce Info files that you can read on line using C-h i
+  in Emacs or the `info' program.
+  Please send comments on the manual to bug-glibc-manual@gnu.org.
+
+* The library now supports SVR4 on i386s (i386-unknown-sysv4).
+
+* Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
+
+* Jason Merrill has contributed a port to the Sequent Symmetry running
+  Dynix version 3 (i386-sequent-dynix).
+
+* The library has been ported to i386s running SCO 3.2.4 (also known as SCO
+  ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
+
+* New function `memory_warnings' lets you arrange to get warnings when
+  malloc is running out of memory to allocate, like Emacs gives you.
+
+* The C library now contains the relocating allocator used in Emacs 19 for
+  its editing buffers.  This allocator (ralloc) minimizes allocation
+  overhead and fragmentation by moving allocated regions around whenever it
+  needs to.  You always refer to a ralloc'd region with a "handle" (a
+  pointer to a pointer--an object of type `void **').
+
+* There is a new `printf' format: `%m' gives you the string corresponding
+  to the error code in `errno'.
+
+* In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
+  or `%[' conversion, but instead of filling in a fixed-sized buffer you
+  pass, the `a' modifier says to fill in a `char **' you pass with a
+  malloc'd string.
+
+* The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
+  `FNM_CASEFOLD'.  `FNM_LEADING_DIR' lets a pattern like `foo*' match a
+  name like `foo/bar'.  `FNM_CASEFOLD' says to ignore case in matching.
+
+* `mkstemp' is a traditional Unix function to atomically create and open a
+  uniquely-named temporary file.
+
+Version 1.05
+
+* The standard location for the file that says what the local timezone is
+  has changed again.  It is now `/usr/local/etc/localtime' (or more
+  precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
+
+* The distribution no longer contains any files with names longer than 14
+  characters.
+
+* `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
+  These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
+
+* New functions `ttyslot' and `syslog' from 4.4 BSD.
+
+Version 1.04
+
+* The configuration process has changed quite a bit.  The `configure'
+  script is now used just like the configuration scripts for other GNU
+  packages.  The `sysdeps' directory hierarchy is much rearranged.
+  The file `INSTALL' explains the new scheme in detail.
+
+* The header files no longer need to be processed into ANSI C and
+  traditional C versions.  There is just one set of files to install, and
+  it will work with ANSI or old C compilers (including `gcc -traditional').
+
+* Brendan Kehoe and Ian Lance Taylor have ported the library to the
+  MIPS DECStation running Ultrix 4.
+
+* The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
+  Tom Quinn contributed the initial code.  The GNU C library can NOT yet be
+  made itself into a shared library.
+
+* Yet further improved support for the i386, running 4.3 BSD-like systems
+  (such as Mach 3 with the Unix single-server), or System V.
+
+* New function `strncasecmp' to do case-insensitive string comparison
+  with limited length.
+
+* New function `strsep' is a reentrant alternative to `strtok'.
+
+* New functions `scandir' and `alphasort' for searching directories.
+
+* New function `setenv' is a better interface to `putenv'.
+
+* Ian Lance Taylor has contributed an implementation of the SVID `ftw'
+  function for traversing a directory tree.
+
+* The GNU obstack package is now also part of the C library.
+  The new function `open_obstack_stream' creates a stdio stream that
+  writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
+  formatted output directly to an obstack.
+
+* Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
+  cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
+
+* `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
+
+* The new functions `strfry' and `memfrob' do mysterious and wonderful
+  things to your strings.
+
+* There are some new test programs: test-fseek, testmb, and testrand.
+
+* Some work has been done to begin porting the library to 4.4 BSD and Linux.
+  These ports are not finished, but are a good starting place for really
+  supporting those systems.
+
+* `/etc/localtime' is now the standard location for the file that says what
+  the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
+  This follows the general principle that `/etc' is the place for all local
+  configuration files.
+
+* The C library header files now use `extern "C"' when used by the C++
+  compiler, so the C library should now work with C++ code.
+
+* The header file <bstring.h> is gone.  <string.h> now declares bcopy,
+  bcmp, bzero, and ffs.  (Update: nowadays these functions are declared
+  in <strings.h>.)
+
+* Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
+  function which uses the `merge sort' algorithm, and is said to be
+  significantly faster than the old GNU `qsort' function.  Merge sort is
+  now the standard `qsort' function.  The new algorithm can require a lot
+  of temporary storage; so, the old sorting function is called when the
+  required storage is not available.
+
+* The C library now includes Michael Glad's Ultra Fast Crypt, which
+  provides the Unix `crypt' function, plus some other entry points.
+
+* The code and header files taken from 4.4 BSD have been updated with the
+  latest files released from Berkeley.
