Snort-rep is a reporting software for Snort that generates both text and HTML output from a syslog file.
What's even better is that it's designed to be used for daily e-mail reports to system administrators. For an example, check out snort-rep-mail. Perhaps most impressively, the HTML output contains direct links to the IDS descriptions of whitehats.com.
If you're looking for specifics on what's new in the latest release, it's version 1.10. The release fixed an off-by-one hour error in syslog parsing when changing from daylight saving time, and added support for portscan2 (Snort 1.9.0).
