Snort 2.9.2 is now available on snort.org, at
http://www.snort.org/snort-downloads/ in the Latest Release section.

2.9.0 RC & later packages are signed with a new PGP key
(that is signed with the previous key).

Snort 2.9.2 introduces the following new capabilities:

  * SCADA (DNP3 and Modbus) preprocessors. Added two new preprocessors
    to support writing rules for detecting attacks for control systems.
    New rule keywords are supported, and DNP3 leverages Stream5 PAF
    support for TCP reassembly.  See the Snort Manual, README.dnp3 and
    README.modbus for details of the configurations and new rule

  * GTP decoding and preprocessor.  Updated the Snort packet decoders
    and added a preprocessor to support detecting attacks over GTP (GPRS
    Tunneling Protocol).  Snort's GTP support handles multiple versions
    of GTP and has a rich configuration set.  See the Snort Manual and
    README.GTP for details.

  * Updates to the HTTP preprocessor to normalize HTTP responses that
    include javascript escaped data in the HTTP response body.  This
    expands Snort's coverage in detecting HTTP client-side attacks.
    See the Snort Manual and README.http_inspect for configuration

  * Added Protocol-Aware Flushing (PAF) support for FTP.

Additionally, the following updates and improvements have been made:

  * Updates to Stream preprocessor to be able to track and store
    "stream" data for non TCP/UDP flows.  Also improvements to handle
    when memory associated with a blocked stream is released and usable
    for other connections.

  * Updates to dce_stub_data to make it act the same as file_data
    and pkt_data rule option keywords in how it interacts with
    subsequent content/pcre/etc rule options.

  * Updates to how Snort handles and processes signals received
    from the OS.

  * Enabled logging of normalized JavaScript to unified2 without the
    use of the --enable-sourcefire configuration option.

  * Improved handling of gaps and overlaps for "first" and "vista"
    policies in Stream5.

  * Added support for signal handler customization. At compile-time,
    Snort can be customized to use different signal numbers.
    This allows problems with overlapping signals to be fixed on a
    per-platform basis, which is especially helpful for the BSDs.
    See the Snort Manual for more details.

Please see the Release Notes and ChangeLog for more details.
