Just as a reminder, Snort 2.9.7.2 is approaching it's EOL (end of life) on August 17, 2015. For more information on our EOL policy, please make sure and visit our EOL page on Snort.org.
Our current version of Snort is 2.9.7.5, and we love our users to be using the most current code and updated ruleset, please start planning your migrations and shifting your software over from 2.9.7.2 to 2.9.7.5 now.
Thanks!
