If you are using this package make note of the distribution change
mentioned below. I have update the MESSAGE to inform users of this and
there is now also a net/snort-rules package with the community rules.
> [*] Distribution Change
> * Rules are no longer distributed as part of the Snort releases, they are
> available as a separate download from snort.org. This was done for
> three reasons:
> 1) To better manage the new rules licensing.
> 2) To reduce the size of the engine download.
> 3) To move the thousands of documentation files for the rules into
> the rules tarballs. If you've ever checked Snort out of CVS you'll
> know why this is a Good Thing.
>
> [*] New additions
> * Added new IP defragmentation preprocessor, Frag3. The frag3 preprocessor
> is a target-based IP defragmentation module, and is intended as a
> replacement for the frag2 module. Check out the README.frag3 for full
> info on this new preprocessor.
>
> * Libprelude support has been added (enable with --enable-prelude).
> Thanks Yoann Vandoorselaere!
>
> * An "ftpbounce" rule detection plugin was added for easier detection of
> FTP bounce attacks.
>
> * Added a new Snort config option, "ignore_ports," to ignore packets
> based on port number. This is similar to bpf filters, but done within
> snort.conf.
>
> [*] Improvements
> * Snort startup messages printed in syslog now contain a PID before each
> entry. Thanks Sekure for initially bringing this up.
>
> * Stream4: Performance improvements.
>
> * Stream4: Added 'max_session_limit' option which limits number of
> concurrent sessions tracked. Added favor_old/favor_new options that
> affect order in which packets are put together for reassembly.
>
> * Stream4: New configuration options to manage flushpoints for improved
> anti-evasion. The flush_behavior option selects flushpoint management
> mode. New flush_base, flush_range, and flush_seed manage randomized
> flushing. Check out the snort.conf file for full config data on the
> new flush options.
>
> * Added two more alerts for BackOrifice client and server packets. This
> allows specific alerts to be suppressed.
>
> * PerfMon preprocessor updated to include more detailed stats for rebuilt
> packets (applayer, wire, fragmented & TCP). Also added 'atexitonly'
> option that dumps stats at exit of snort, and command line -Z flag to
> specify the file to which stats are logged.
>
> * Added new Http Inspect config item, "tab_uri_delimiter," which if
> specified, lets a tab character (0x09) act as the delimiter for a URI.
>
> * Added a '-G' command line flag to snort that specifies the Snort
> instance log identifier. It takes a single argument that can be either
> hex (prefaced with 0x) or decimal. The unified log files will include
> the instance ID when the -G flag is used.
>
> * "Same SRC/DST" (sid 527) and "Loopback Traffic" (sid 528) are now
> handled in the IP decoder. Those sids are now considered obsolete.
>
> * Http_Inspect "flow_depth" option now accepts a -1 value which tells
> Snort to ignore all server-side traffic.
>
> * RPMs have been updated to be more portable, and also now include a
> "--with inline" option for those wanting to build Inline RPMs. Thanks
> Daniel Wittenberg and JP Vossen for your help!
>
> * Many, many bug fixes have also gone into this release, please see the
> ChangeLog for details.
