The phpBB Group is pleased to announce the release of phpBB 2.0.18, "The Halloween Special" release.  This is a major update to the 2.0.x codebase and includes fixes for numerous bugs reported by users to our Bug Tracker, as well as updates to those issues identified by the recent security audit of the code and a couple of security issues reported to us. In addition we have backported a further feature from our "Olympus" codebase to change the way automatic logins are handled.
