This is a reminder that SNORT version 2.9.11.0 will be shut down tomorrow, Jan. 10. We are working on revising Snorts end-of-life policy for other versions going forward. We will begin to shut down versions of Snort that make up 10 percent or less of our downloads or superseded versions have been around for five years, which ever comes first. We will release more details about this in the future.”]
