Copyright (C) 2002, 2003, 2004, 2005, 2006 Simon Josefsson
See the end for copying conditions.

Note that changes to the GNU SASL Library is documented in lib/NEWS.
This file track changes to the remaining, non-library, parts of GNU
SASL.  That include the manual, the command line tool, and self tests.

* Version 0.2.13 (unreleased)

** Update of gnulib files.
Further improves portability to MinGW.

** The manual doesn't have any invariant sections.

* Version 0.2.12 (released 2006-03-08)

** Update of gnulib files.
Improves portability to Mingw32.

* Version 0.2.11 (released 2006-02-07)

** Ported to Windows by cross-compiling using Mingw32.
Using Debian's mingw32 compiler, you can build it for Windows by invoking
`./configure --host=i586-mingw32msvc --disable-gssapi'.

** Update of gnulib files.

* Version 0.2.10 (released 2005-10-23)

** Work around bug in GnuTLS that made the command line tool exit after
** failing to write a zero length message to the peer.

** Don't use GnuTLS if gnutls_certificate_verify_peers2 isn't present.

** Update of gnulib files.

* Version 0.2.9 (released 2005-10-07)

** Update of gnulib files.

* Version 0.2.8 (released 2005-09-08)

** The gsasl tool now support STARTTLS for IMAP and SMTP using GnuTLS.

** The --client and --server parameters for the gsasl tool now work properly.

** The --client and --server stdin/stdout modes now use the readline library.

** Fixed build problems in getpass on uClibc and Mingw32 platforms.

** Kinyarwanda translation added.

* Version 0.2.7 (released 2005-08-25)

** Fix build problems when cross-compiling to uClibc and Mingw32 platforms.

** Detecting and using the readline library has been improved.

* Version 0.2.6 (released 2005-08-08)

** The gsasl tool now try to connect to all addresses for a server name.

** The help-gsasl@gnu.org mailing list is now mentioned in documentation.

** The license template in files were updated with the new FSF address.

** Update of gnulib files.

* Version 0.2.5 (released 2005-02-08)

** Added self test of EXTERNAL mechanism.

** Vietnamese translation added, thanks to Clytie Siddall.

* Version 0.2.4 (released 2005-01-01)

** The CRAM-MD5 mechanism is now preferred over DIGEST-MD5.
This decision was based on recent public research that suggest MD5 is
broken, while HMAC-MD5 not immediately compromised, and the lack of
public analysis on what consequences the MD5 break have for
DIGEST-MD5.  Support for CRAM-SHA1 is under investigation, to enable
users to avoid MD5 completely

** Fixed a bug that prevented SMTP client from working.

** New configure option --disable-obsolete to remove backwards compatibility.
This is mostly intended to be used when compiling for platforms with
constrained memory/space resources.

** DIGEST-MD5 rewritten and enabled by default (see lib/NEWS for details).

** Command line tool now query for realm, hostname and service name properly.

** Documentation updates and improvements.

** Self test improvements.

** Update of gnulib files.

* Version 0.2.3 (released 2004-12-15)

** Fix example code to handle base64 encoded data properly.

** DIGEST-MD5 is disabled by default, pending a rewrite for the new API.

** Command line tool uses new callback interface to the library.

** Command line tool uses "iconvme" from gnulib for UTF-8 string conversion.

** Server mode in the command line tool does not work currently.
It is unclear if this feature was ever that useful.  If there are no
objections, it will be removed completely in future versions.

** Documentation fixes.

** Fix self test bugs.

* Version 0.2.2 (released 2004-11-29)

** Update of gnulib files.

* Version 0.2.1 (released 2004-11-19)

** Documentation fixes; the old callback API functions are marked as obsolete.

* Version 0.2.0 (released 2004-11-07)

** Added new directory examples/ with complete examples for new API.

** Documentation improvements.
For example, you can now browse the GNU SASL API manual using DevHelp.

** Update of gnulib files.

** More self tests.

** Translation fixes.

* Version 0.1.4 (released 2004-08-08)

** Revamp of gnulib compatibility files.

** More translations.
German (by Roland Illig), Basque (by Mikel Olasagasti), French (by
Michel Robitaille), Irish (by Kevin Patrick Scannell), Dutch (by Elros
Cyriatan), Polish (by Jakub Bogusz), Romanian (by Laurentiu Buzdugan),
and Serbian (by Aleksandar Jelenak).

* Version 0.1.3 (released 2004-08-04)

** Command line tool support IPv6 (and other protocol families).
Requires that your system has `getaddrinfo'.

** Command line behaviour for gsasl tool improved.
The --client and --imap parameters are now the default.  The --connect
host and port can now be specified directly.  If --authentication-id
is not specified, the username of the user invoking gsasl is used
(i.e., getpwuid(getuid)->pw_name).  Alltogether, this allows simple
usage, as in `gsasl mail.example.com' to connect, via IMAP, to
mail.example.com.

* Version 0.1.2 (released 2004-07-16)

** The SMTP mode in `gsasl' should now work.

** Cross compile builds should work.
It should work for any sane cross compile target, but the only tested
platform is uClibc/uClinux on Motorola Coldfire.

** The GNU Readline library is used to read data, if available.

** Passwords read from stdin are not echoed to the terminal.

* Version 0.1.1 (released 2004-06-26)

** In the command line client, the default quality of protection is now none.

* Version 0.1.0 (released 2004-04-16)

** The library re-licensed to LGPL and distributed as a separate package.
This means a fork of this NEWS file, all the entries below relate to
the combined work of earlier versions.  New entries above does not
document user visible changes for the library ("libgsasl"), for that
see NEWS in the lib/ sub-directory, which is also distributed as a
stand-alone package.

* Version 0.0.14 (released 2004-01-22)

** Moved all mechanism specific code into sub-directories of lib/.
Each backend is built into its own library (e.g., libgsasl-plain.so),
to facilitate future possible use of dlopen to dynamically load
backends.

** Moved compatibility files (getopt*) to gl/, and added more (strdup*).

* Version 0.0.13 (released 2004-01-17)

** Nettle (the crypto functionality, crypto/) has been updated.
This fixes two portability issues, the new code should work on
platforms that doesn't have inttypes.h and alloca.

* Version 0.0.12 (released 2004-01-15)

** Protocol line parser in 'gsasl' tool more reliable.
Earlier it assumed two lines were sent in one packet in one place, and
sent as two packets in another place.

** Various bugfixes.

* Version 0.0.11 (released 2004-01-06)

** The client part of CRAM-MD5 now uses SASLprep instead of NFKC.
This aligns with draft-ietf-sasl-crammd5-01.

** The CRAM-MD5 challenge string now conform to the proper syntax.

** The string preparation (SASLprep and trace) functions now work correctly.

** DocBook manuals no longer included.
The reason is that recent DocBook tools from the distribution I use
(Debian) fails with an error.  DocBook manuals may be included in the
future, if I can get the tools to work.

** API and ABI modifications.
GSASL_SASLPREP_ERROR: ADD.

* Version 0.0.10 (released 2003-11-22)

** The CRAM-MD5 server now reject invalid passwords.
The logic flaw was introduced in 0.0.9, after blindly making code
changes to shut up valgrind just before the release.

** Various build improvements.
Pkg-config is no longer needed.  GTK-DOC is only used if present.

* Version 0.0.9 (released 2003-11-21)

** Command line client can talk to SMTP servers with --smtp.

** DocBook manuals in XML, PDF, PostScript, ASCII and HTML formats included.

** Token parser in DIGEST-MD5 fixed, improve interoperability of DIGEST-MD5.

** Libgcrypt >= 1.1.42 is used if available (for CRAM-MD5 and DIGEST-MD5).
The previous libgcrypt API is no longer supported.

** CRAM-MD5 and DIGEST-MD5 no longer require libgcrypt (but can still use it).
If libgcrypt 1.1.42 or later is not found, it uses a minimalistic
cryptographic library based on Nettle, from crypto/.  Currently only
MD5 and HMAC-MD5 is needed, making a dependence on libgcrypt overkill.

** Listing supported server mechanisms with gsasl_server_mechlist work.

** Autoconf 2.59, Automake 1.8 beta, Libtool CVS used.

** Source code for each SASL mechanism moved to its own sub-directory in lib/.

** The command line interface now uses getopt instead of argp.
The reason is portability, this also means we no longer use gnulib.

** API and ABI modifications.

* Version 0.0.8 (released 2003-10-11)

** Improved GSSAPI implementation detection.
Auto detection should work, unless you have both MIT and Heimdal, or
wish to override the default that prefer GSS over Heimdal over MIT.
In that case, use --enable-gssapi=mit or --enable-gssapi=heimdal.

** GNU SASL contain APIs for internationalized string processing via SASLprep.
You no longer have to use Libidn directly.

** Man pages for all public functions are included.

** GNULib is used for compatibility functions.
The directory gl/ is dedicated for GNULib functions, and replace the
earlier ad-hoc usage of argp, memset, etc.

** GNU SASL will be C89 compatible.
The library itself (lib/*) only use C89.  The remaining parts (src/
and tests/) can use C89 and any functionality from GNULib.  This
decision may be revised in the future, if it turns out there are
problems with this.

** Improvements for embedded or otherwise limited systems.
The math library (-lm) is no longer required.  All client code can be
disabled by --disable-client, and all server code can be disabled by
--disable-server.  The internationalized string processing library can
be disabled by --without-stringprep.

** Gettext 0.12.1 and Libtool 1.5 is used.

** Libgcrypt from CVS (1.1.42) is not supported.
Recent libgcrypt is API incompatible with earlier released versions.
If a too recent version is installed, it will not be used.

** Fix command line tool '--connect --imap' on Solaris.

** Bug fixes.

** API and ABI modifications.
Gsasl_client_callback_maxbuf: CHANGED: 'int' was replaced with 'size_t'.
Gsasl_server_callback_maxbuf: CHANGED: 'int' was replaced with 'size_t'.
gsasl_client_mechlist: NEW.
gsasl_server_mechlist: NEW.
gsasl_client_listmech: DEPRECATED: use gsasl_client_mechlist instead.
gsasl_server_listmech: DEPRECATED: use gsasl_server_mechlist instead.
gsasl_stringprep_nfkc: NEW.
gsasl_stringprep_saslprep: NEW.
gsasl_stringprep_trace: NEW.

* Version 0.0.7 (released 2003-06-02)

** Two new GSS libraries supported for the GSS-API mechanism.
See http://josefsson.org/gss/ for GSS, which uses Shishi for Kerberos 5.
See http://www.pdc.kth.se/heimdal/ for Heimdal (Kerberos 5).

** Bug fixes.

* Version 0.0.6 (released 2003-03-17)

** Gettext not included.
Due to some conflicts between libtool and gettext, if you want i18n on
platforms that does not already have a useful gettext implementation,
you must install GNU gettext before building this package.  If you
don't care about i18n, this package should work fine (except for i18n,
of course).

** Rudimentary support for KERBEROS_V5.
Only enable if you want to write code.  This adds two new API errors;
GSASL_KERBEROS_V5_INIT_ERROR, GSASL_SHISHI_ERROR.

** Added API function: gsasl_client_callback_realm_set.
Specifies which realm the client belongs to.

** Bugfixes.
User visible aspects includes not building the API Reference Manual
with GTK-DOC by default, if you want it use configure parameter
--enable-gtk-doc.

* Version 0.0.5 (released 2003-01-27)

** Command line application "gsasl" now supports --imap and --connect.
The --imap parameter makes it use a IMAP-like negotiation on
stdin/stdout.  The --connect parameter makes it connect to a host over
TCP, and talk to it instead of stdin/stdout.  This allows it to be
used as a simple test tool to connect to IMAP servers.  Currently
integrity and confidentiality is not working properly, so if you use
DIGEST-MD5 you currently have to specify --quality-of-protection=auth.

** Texinfo documentation added for command line tool.

** Libgcrypt initialization no longer causes a warning to be printed.

** Added API reference manual in HTML format, generated using GTK-DOC.
See doc/reference/, in particular doc/reference/html/index.html.

** GNU Libidn replaces Libstringprep.
Although it is still stored in the libstringprep/ directory for CVS
reasons.

** Bug fixes for DIGEST-MD5 and GSSAPI.

* Version 0.0.4 (released 2002-12-13)

** License changed to GPL.

** Official GNU project.

* Version 0.0.3 (released 2002-12-05)

** New gsasl arguments --application-data and --no-client-first.

** Bug fixes (client sends first, memory leaks, compiler warnings, more).

* Version 0.0.2 (released 2002-11-07)

** Includes a copy of libstringprep 0.0.2 for Unicode NFKC
normalization and locale charset to UTF-8 string conversion, and
preparation for the future if a SASL Stringprep profile is created.
If libstringprep is already installed, it is used by default.  You can
force the use of the internal version with
--without-system-libstringprep.

** Uses pkg-config instead of libgsasl.m4 + libgsasl-config.in, and
for finding libntlm (requires libntlm 0.3.1 or later).

** Self tests for several mechanisms.

** The API now allows mechanisms to return data even when returning
GSASL_OK (earlier only on GSASL_NEEDS_MORE).

** Bug fixes.

* Version 0.0.1 (released 2002-10-12)

** APIs for integrity and confidentiality protection of application
payload data.

** DIGEST-MD5 support for integrity protection.

* Version 0.0.0 (released 2002-10-07)

** Initial release.
