The first cumulative update for our new SharePoint versions is available. Unfortunately we cannot offer a full-server package so more steps are needed in case you want to install all “packlets”.
It is planned to have Full Server packages with August CU so in case you can wait it might be a better idea. I do not want to rewrite everything so please have a look on the two blogs from my colleagues:
Stefan Gossner: The first cumulative update for SharePoint 2010 family has been released
Patrick Heyde: SharePoint 2010 - JuneCU 2010 released
