Today in the PASS summit, Microsoft announced SQL Server 2012 Service Pack1 which is made available to download for public officially. You can download this from here.
One cool thing to notice is that URL provides you with two flavors of downloads -SP1 Update and SP1 Slipstream 
Personally, I like this move by Microsoft to provide Slipstream Downloads. You know why, if you’ve had to prepare your own SlipStreams for your SQL Server Installations at work!
You can get the List of Bugs got fixed in SP1 here.
