Snort 2.9.3 RC is now available on snort.org, at
http://www.snort.org/snort-downloads/ in the Latest Development
Release section.

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

Snort 2.9.3 introduces the following new capabilities:

[*] New additions
  * Updates to flowbit rule option to allow for OR and AND
    of individual bits within a single rule, and allow flowbits
    to be used in multiple groups.  See README.flowbits and
    the Snort manual for details.

  * Dynamic output plugin architecture to provide an API that
    developers can write their own output mechanisms to log alert
    and packet data from Snort.  Some output plugins have been
    removed as a result of this to be maintained by their
    respective authors.

  * Update to dcerpc2 preprocessor for improved accuracy and
    handling of different OSs for SMB processing.  See README.dcerpc2
    and the Snort manual for details.

  * Updates to reputation preprocessor for handling of whitlelist
    and trustlists and zone information.  See README.reputation
    and the Snort manual for details.

  * Updates to the packet decoders to support pflog v4.

[*] Improvements
  * Update to return error messages through the control socket.

  * Updates to the processing of email attachments for better
    handling of non-encoded attachments, and improved memory
    management for attachment processing.

  * Improvements in HTTP Inspect for better performance with gzip
    decompression.  Also improvements for handling simple responses,
    encoded query strings, transfer encoding and chunk encoding

  * Fix logging of multiple unified2 alerts with reassembled packets.

  * Compiler warning cleanup across multiple platforms.

  * Added 116:458 and 116:459 to cover fragmentation issues.

  * Added detailed documentation of unified2 logging configuration and

  * Removed --enable-decoder-preprocessor-rules configure option and
    hardened preprocessor and decoder rule event code.  To enable old
    behavior such that specific preprocessor and decoder rules don't
    have to be explicity added to snort.conf, add "config
    autogenerate_preprocessor_decoder_rules" to your snort.conf.

  * Fixed SMTP mempool allocation for significant memory savings.  Also
    tweaked memory required per stream5 session tracker.

  * Force exact versioning match of running dynamic engine and dynamic
    engine used to build SO rules.  This will cause Snort to generate
    an error and exit if .so rules are used from an older version.

  * User can now query reputation pp for routing table and management
