Snort 2.9.3 Beta Now Available

Snort 2.9.3 Beta is now available on snort.org, at https://www.snort.org/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.

 * 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 processing.

 * Fix logging of multiple unified2 alerts with reassembled packets.

 * Compiler warning cleanup across multiple platforms.
