[*] Updates
   * Fix installer packages to include correct version of sensitive data
     preprocessor for linux and Windows

   * Eliminate false positives when using fast_pattern:only and having only
     one http content in the pattern matcher.

   * Address false positives in FTP preprocessor with string format verification.
     Also addressed issue with handling of response codes to data transfer
     commands where the response code didn't contain a message.

2010-04-22 - Snort 2.8.6

[*] New Additions
   * HTTP Inspect now splits requests into 5 components -
     Method, URI, Header (non-cookie), Cookies, Body.
     Content and PCRE rule options can now search one or more of these buffers.

     HTTP server-specific configurations to normalize the HTTP header and/or
     cookies have been added.

     Support gzip decompression across multiple packets.

   * Added a Sensitive Data preprocessor, which performs detection of
     Personally Identifiable Information (PII).  A new rule option is available
     to define new PII.  See README.sensitive_data and the Snort Manual
     for configuration details.

   * Added a new pattern matcher and related configurations.  The new pattern
     matcher is optimized to use less memory and perform at AC speed.

[*] Improvements
   * Addressed problem to resolve output obfuscation affecting packets
     when Snort is inline.

   * Preprocessors with memcap settings can now be configured in a "disabled"
     state.  This allows you to configure that memcap globally, but only enable
     the preprocessor in targeted configurations.
