I apologise for the delay, but I've finally managed to get the announcement out on SourceForge. Most of the news announcements are now on the WordPress Blog on http://www.freepbx.org, and the best place to catch up with the latest news is there.
For those that haven't been reading, 2.2.0 has a new look, a pile of new modules, and over 200 bug fixes. There is a minor problem with ENUM lookup, and a single-line fix is available on the Wordpress Blog, if you do need to use it.
Downloads are available from mirror.freepbx.org, or from sourceforge.
