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.

We would like to thank all of those who take part in the security audit of the code
for their work.
