Snort 2.9.7 is now available on snort.org at
http://www.snort.org/downloads in the Snort Stable Release section.

A new DAQ build is also available that updates support for a few
operating systems.

Snort 2.9.7 includes a major new feature for Application Identification,
our OpenAppID capability.

In conjunction with this release, are shifting the license for the OpenAppId
content to GPLv2 to encourage more use and submission back to Cisco.  If

2014-10-24 - Snort
[*] New additions
* Application Identification Preprocessor, when used in conjunction with
  OpenAppID detector content, that will identify application protocol,
  client, server, and web applications (including those using SSL) and
  include the info in Snort alert data. In addition, a new rule option
  keyword 'appid' that can be used to constrain Snort rules based on one
  or more applications that are identified for the connection. Separate
  prepackaged RPMs with App Open ID are available.  See README.appid
  for further details.

* A new protected_content rule option that is used to match against a
  content that is hashed.  It can be used to obscure the full context
  of the rule from the administrator.

* Protocol Aware Flushing (PAF) improvements for SMTP, POP, and IMAP to
  more accurately process different portions of email messages and file

* Added ability to test normalization behavior without modifying
  network traffic.  When configured using na_policy_mode:inline-test,
  statistics will be gathered on packet normalizations that would have
  occurred, allowing less disruptive testing of inline deployments.

* The HTTP Inspection preprocessor now has the ability to decompress
  DEFLATE and LZMA compressed flash content and DEFLATE compressed PDF
  content from http responses when configured with the new
  decompress_swf and decompress_pdf options. This enhancement can be
  used with existing rule options that already match against
  decompressed equivalents.

* Added improved XFF support to HttpInspect. It is now possible to
  specify custom HTTP headers to use in place of 'X-Forwarded-For'. In
  situations where traffic may contain multiple XFF-like headers, it is
  possible to specify which headers hold precedence.

* Added additional support for Heartbleed detection within the SSL
  preprocessor to improve performance.

* Added control socket command to dump packets to a file.  See
  README.snort_dump_packets_control for details.

* Added an option to suppress configuration information logging to output.

* The Stream5 preprocessor functionality is now split between the new
  Session and Stream6 preprocessors.

[*] Improvements
* Maximum IP6 extensions decoded is now configurable.

* Update active response to allow for responses of 1500+ bytes that span
  multiple TCP packets.

* Check limits of multiple configurations to not exceed a maximum ID of 

* Updated the error output of byte_test, byte_jump, byte_extract to
  including details on offending options for a given rule.

* Update build and install scripts to install preprocessor and engine
  libraries into user specified libdir.

* Improved performance of IP Reputation preprocessor.

* The control socket will now report success when reloading empty IP
  Reputation whitelists/blacklists.

* All TCP normalizations can now be enabled individually. See
  README.normalize for details on using the new options. For
  consistency with other options, the "urp" tcp normalization keyword
  now enables the normalization instead of disabling it.

* Lowered memory demand of Unicode -> ASCII mapping in HttpInspect.

* Updated profiler output to remove duplicate results when using
  multiple configurations.

* Improved performance of FTP reassembly.

* Improved compatibility with Mac OSX 10.9 (Mavericks), OpenBSD,
  FreeBSD, and DragonFlyBSD
