* Version 1.13 (released 2009-03-06)

** libidn: Use a LD version script on platforms where it is supported.
Currently only GNU LD and the Solaris linker supports it.  This helps
Debian package tools to produce better dependencies.  Before we used
Libtool -export-symbols-regex that created an anonymous version tag.
Libidn uses -export-symbols-regex if the system does not support LD
version scripts, but that only affect symbol visibility.

** libidn: Compiled with -fvisibility=hidden by default if supported.
Currently only GCC supports it for ELF targets.  This hides internal
symbols and has other advantages, see

** libidn: Compiled with warning flags only when GCC is used.
This avoids the problem that some flags confuse non-GCC compilers, for
example -fdiagnostics-show-option.  Reported by

** doc: The idn_free function is now documented.
Suggested by "Sisyphus" <address@hidden>.

** API and ABI is backwards compatible with the previous version.

GNU Libidn is a fully documented implementation of the Stringprep,
Punycode and IDNA specifications.  Libidn's purpose is to encode and
decode internationalized domain names.  The native C, C# and Java
libraries are available under the GNU Lesser General Public License
version 2.1 or later.

The library contains a generic Stringprep implementation.  Profiles for
Nameprep, iSCSI, SASL, XMPP and Kerberos V5 are included.  Punycode and
ASCII Compatible Encoding (ACE) via IDNA are supported.  A mechanism to
define Top-Level Domain (TLD) specific validation tables, and to compare
strings against those tables, is included.  Default tables for some TLDs
are also included.

Libidn is developed for the GNU/Linux system, but runs on over 20 Unix
platforms (including Solaris, IRIX, AIX, and Tru64) and Windows.  The
library is written in C and (parts of) the API is also accessible from
C++, Emacs Lisp, Python and Java.  A native Java and C# port is

Also included is a command line tool, several self tests, code examples,
and more, all licensed under the GNU General Public License version 3.0
or later.

Improving Libidn is costly, but you can help!  We are looking for
organizations that find Libidn useful and wish to contribute back.  You
can contribute by reporting bugs, improve the software, or donate money
or equipment.

Commercial support contracts for Libidn are available, and they help
finance continued maintenance.  Simon Josefsson Datakonsult AB, a
Stockholm based privately held company, is currently funding Libidn
maintenance.  We are always looking for interesting development
projects.  See for more details.
