Seam is about to move from CVS to SVN (in the next couple of days).
If you are tracking Seam CVS, you'll notice that once this happens there will be no more updates to the CVS repository.
The new repository address is: http://anonsvn.jboss.org/repos/seam
If you are watching commits, you'll need to subscribe to the firstname.lastname@example.org list (when it is created).
I'll post back here when the migration is complete.
