Libidn 1.30 released

[Simon Josefsson]

GNU Libidn is a fully documented implementation of the Stringprep,
Punycode and IDNA specifications.  Libidn's purpose is to encode and
decode internationalized domain name strings.  There are native C, C#
and Java libraries.

Noteworthy changes since the last release (from NEWS file):

* Version 1.30 (released 2015-03-02) [stable]

** libidn: The punycode.{c,h} files were re-imported from RFC 3492bis.
A comment explaining the origin and what was changed was added.

** Bump gettext to 0.19.3.

** Use LT_INIT instead of AC_LIBTOOL_WIN32_DLL.

** i18n: Added Hungarian translation.  Updated some other languages.
Thanks to Balázs Úr.

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

The C 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.

The Stringprep API consists of two main functions, one for converting
data from the system's native representation into UTF-8, and one
function to perform the Stringprep processing.  Adding a new Stringprep
profile for your application within the API is straightforward.  The
Punycode API consists of one encoding function and one decoding
function.  The IDNA API consists of the ToASCII and ToUnicode functions,
as well as an high-level interface for converting entire domain names to
and from the ACE encoded form.  The TLD API consists of one set of
functions to extract the TLD name from a domain string, one set of
functions to locate the proper TLD table to use based on the TLD name,
and core functions to validate a string against a TLD table, and some
utility wrappers to perform all the steps in one call.

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
included.

Also included is a command line tool, several self tests, code examples,
and more.

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 http://josefsson.org/ for more details.
