We are on track for a Jan 21st release date for v2.5.

You can monitor the open source package by going to http://sourceforge.net/projects/sugarcrm/ and clicking on the "Monitor" icon (small email image) next to the SugarCRM release packages. This will notify you when the release package is made available. You can also monitor our forums at http://www.sugarcrm.com/forums for the availability announcement.

Good stuff!
