GNU SASL 1.7.4 released (development version)

From: Simon Josefsson
Subject: GNU SASL 1.7.4 released (development version)
Date: Wed, 16 May 2012 01:41:30 +0200
User-agent: Gnus/5.130006 (Ma Gnus v0.6) Emacs/23.3 (gnu/linux)

GNU SASL is a modern C library that implement the standard network
security protocol Simple Authentication and Security Layer (SASL).  The
framework itself and a couple of common SASL mechanisms are implemented.
GNU SASL can be used by network applications for IMAP, SMTP, XMPP and
similar protocols to provide authentication services.  Support for the
more recent SCRAM-SHA-1, OPENID20 and SAML20 mechanisms is included.

Note!  This is the second release candidate of 1.8.0.  Please test this
release as if it were a new stable release that replaces the earlier
1.4.x and 1.6.x branches.  It should be a drop-in.  I plan to make the
final release later this month.

NEWS entries:

** libgsasl: Reverted unification of OpenID and SAML properties/callbacks.
The reason was that client and servers needs to know whether it is
SAML or OpenID that is used, and using the same property and callback
symbol for both makes this more difficult.

** GSS-API server: Don't output zero-length tokens on context init success.
Reported by Andreas Oberritter <address@hidden>.

** GSS-API server: Only proceed to next step when context is established.
Reported by Andreas Oberritter <address@hidden>.

** Doc fixes and updates for the callback/property change in the library.
See lib/NEWS for details.  This affects SAML and OpenID.

** Rewrote DIGEST-MD5 code to avoid false positive complaint from valgrind.

** Slight fixes to Windows build script.

** i18n: Updated translations.

** Update gnulib files.

** API and ABI modifications.

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

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