I received word through a listserve from the coastguard http://cgls.uscg.mil/ http://cgls.uscg.mil/ Once you agree to the security whatever go to 'hosted groups.' I subscribe to 'Notice Advisory Navstar Users,' which issues reports about GPS updates. They notified us 30 May 2012. Edit: acomjean looks to have a better source (but if you are looking to subscribe to the Local Notice to Mariners in your district, which I strongly encourage if you boat on the ocean, my links will get you there too!).
