As a reminder, Snort 2.9.5.6 is approaching its End of Life next week (1-21-2014), at which point we will no longer be building and distributing that version of the ruleset.
While the amount of people that are downloading this ruleset is very small, we want to encourage you to upgrade to a currently supported version (2.9.6.2, 2.9.7.0) in order to stay current.
In addition, please review your Oinkmaster and PulledPork configuration to make sure it is downloading the correct version of the ruleset as well. We have about 30,000 people a day that are requesting invalid versions, and would love to see those people migrate to a current version as well.
Especially those of you that are attempting to download version 2.2 of the ruleset, which we haven't produced in about 12 years.
