Snort 2.9.4 is now available on snort.org, at
http://www.snort.org/snort-downloads/ in the Latest Release section.

Please note: & later packages are signed with a new PGP key
(that key is signed with the previous key).

Snort 2.9.4 includes changes for the following:

[*] New additions

  * Consolidation of IPv6 -- now only a single build supports both
    IPv4 & IPv6, and removal of the IPv4 "only" code paths.

  * File API and improvements to file processing for HTTP downloads
    and email attachments via SMTP, POP, and IMAP to facilitate
    broader file support

  * Use of address space ID for tracking Frag & Stream connections
    when it is available with the DAQ

  * Logging of packet data that triggers PPM for post-analysis via
    Snort event

  * Decoding of IPv6 with PPPoE

  * Added an API call to add a service to a host in the attribute table.
    Remove the unused live attribute update code.

[*] Improvements

  * Update to Stream5 PAF for handling gaps in the sequence numbers of
    packets being reassembled.

  * Selection of the Stream TCP policy based on the server rather than
    the destination of first packet seen by Snort

  * Allow disabling of global thresholds via a count of -1

  * Prevent blocking duplicate SYNs when using inline normalization

  * Add SSLv3 backwards compatibility support for SSLv2 ClientHello

  * Allow active responses to packets without data (eg, a TCP SYN)

  * Changed logic of option evaluations for shared library rules that
    use a custom evaluation function to match that of the builtin logic
    when the NOT_FLAG is used.  The 'NOT' matching now happens within
    each of the individual rule option evaluation functions.

  * Updated SMTP preprocessor to better handle commands that have
    corresponding data on a subsequent line to reduce false positives.
    3 commands fall into this category - X-EXPS, XEXCH50, and BDAT.

  * Improve support for encapsulated & tunneling protocols to block or
    fastpath a connection within the tunnel rather applying that to
    the whole tunnel.
