Snort 2.9.0 is now available on snort.org, at

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

Snort 2.9.0 introduces:

   * Feature rich IPS mode including improvements to Stream for
     inline deployments.  Additionally a common active response API is
     used for all packet responses, including those from Stream,
     Respond, or React.  A new response module, respond3, supports the
     syntax of both resp & resp2, including strafing for passive
     deployments.  When Snort is deployed inline, a new preprocessor
     has been added to handle packet normalization to allow Snort
     to interpret a packet the same way as the receiving host.

   * Use of a Data Acquisition API (DAQ) that supports many different
     packet access methods including libpcap, netfilterq, IPFW, and
     afpacket.  For libpcap, version 1.0 or higher is now required.
     The DAQ library can be updated independently from Snort and is
     a separate module that Snort links.  See README.daq for details
     on using Snort and the new DAQ.

   * Updates to HTTP Inspect to extract and log IP addresses from
     X-Forward-For and True-Client-IP header fields when Snort generates
     events on HTTP traffic.

   * A new rule option 'byte_extract' that allows extracted values to
     be used in subsequent rule options for isdataat, byte_test,
     byte_jump, and content distance/within/depth/offset.

   * Updates to SMTP preprocessor to support MIME attachment decoding
     across multiple packets.

   * Ability to "test" drop rules using Inline Test Mode.  Snort will
     indicate a packet would have been dropped in the unified2 or
     console event log if policy mode was set to inline.

   * Two new rule options to support base64 decoding of certain pieces
     of data and inspection of the base64 data via subsequent rule

   * Updates to the Snort packet decoders for IPv6 for improvements to
     anomaly detection.

   * Added a new pattern matcher that supports Intel's Quick Assist
     Technology for improved performance on supported hardware
     platforms.  Visit http://www.intel.com to find out more about
     Intel Quick Assist.  The following document describes Snort's
     integration with the Quick Assist Technology

   * Reference applications for reading unified2 output that handle
     all unified2 record formats used by Snort.

   * Ability for rules to control TCP stream reassembly via a new
     rule option.

Please see the Release Notes and ChangeLog for more details.
