Announcing ModSecurity version 2.9.4

We are happy to announce ModSecurity version 2.9.4!

Version 2.9.4 does not include any new features but fixes and enhancements. Users from 2.9.4 can count on an expanded list of countries on the GeoIP operations, including BL BQ CW MF SS SX. Also, the timestamp on log entries was extended to support microseconds. We have decided to remove the Core Ruleset(CRS) from the Windows(TM) Installer, giving users the freedom to update and manage their rules with more flexibility. If you are an Apache user, this is the version you are looking forward to running on your server. Family 2.x is the recommendation for Apache users; 3.x is the recommendation for Nginx users.
