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 TISCII.

* New header  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  header file
  with the same behavior as the Linux system call of the same name.
