We are pleased to announce the availability of GnuTLS version 1.3.3,
another release on the experimental 1.3.x branch.
The goal of 1.3.x will be to add support for TLS Pre-Shared-Keys and
TLS Inner Application (TLS/IA). Other planned improvements in 1.3.x
are system-independent resume data structures, modularization of the
bignum operations, and TLS OpenPGP improvements. So far, the TLS-PSK,
TLS/IA and system-independent resume data goals have been met.
GnuTLS is a modern C library that implement the standard network
security protocol Transport Layer Security (TLS), for use by network
Improving GnuTLS is costly, but you can help! We are looking for
organizations that find GnuTLS useful and wish to contribute back.
You can contribute by reporting bugs, improve the software, or donate
money or equipment.
Commercial support contracts for GnuTLS are available, and they help
finance continued maintenance. Simon Josefsson Datakonsult, a
Stockholm based privately held company, is currently funding GnuTLS
maintenance. We are always looking for interesting development

OpenPGP key identified by the following information:

Noteworthy changes since version 1.3.2:
** New API to access the TLS master secret.
When possible, you should use the TLS PRF functions instead.
Suggested by Jouni Malinen <jkmaline at cc.hut.fi>.
** Improved handling when multiple libraries use GnuTLS at the same time.
Now gnutls_global_init() can be called multiple times, and
gnutls_global_deinit() will only deallocate the structure when it has
been called as many times as gnutls_global_init() was called.
** Added a self test of TLS resume functionality.
** Fix crash in TLS resume code, caused by TLS/IA changes.
** Documentation fixes about thread unsafety, prompted by
** discussion with bryanh at giraffe-data.com (Bryan Henderson).
In particular, gnutls_global_init() and gnutls_global_deinit() are not
thread safe. Careful callers may want to protect the call using a
mutex. The problem could also be ignored, which would cause a memory
leak under rare conditions when two threads invoke the function
roughly at the same time.
** Add 'const' keywords in various places, from Frediano ZIGLIO.
** The code was indented again, including the external header files.
** API and ABI modifications:
New functions to retrieve the master secret value:
Add a 'const' keyword to existing API:
