When RavenNuke™ v2.20.00 was released, we announced that a maintenance release would follow within 2-3 weeks.  Not all the documentation was up to date and we knew there would be some minor issues found by our faithful users .  We are expecting to release the fixes by this Saturday, March 1, 2008.  There are no major changes to code nor any database changes so the upgrade really should be pretty painless assuming you are using v2.20.00.  Otherwise you will need to follow the documented upgrade instructions for your version.

Note: 

Update: We have to reschedule for tomorrow, March 2, 2008.  A couple of issues/resolutions are still being tested and we don't want to be presumptuous and just assume that it works
