Woohoo!  After a bit of a delay (my calendar says it is July 22nd), the June CU is finally available for SharePoint and Project Server 2010.

Project Server 2010 is built on top of SharePoint Server 2010, and SharePoint Server 2010 is built on top of SharePoint Foundation, so if you are running Project Server 2010, you’ll need all 3 updates, and if you are running SharePoint Server 2010 you’ll need the top two hotfixes.

Before installing the updates, make sure you read through the KB articles above to see if you are impacted by any of the bugs that were fixed, and then head on over to the SharePoint 2010 Update Resource Center to learn how we recommend you test and implement updates for SharePoint 2010.
