Yesterday the first cumulative update for the SharePoint 2010 product family has been released as a delayed June 2010 CU. Unlike the WSS 3.0 and MOSS 2007 cumulative updates this first cumulative update is not available as server package but has been released as 6 individual packages. You can download the fixes using the following links:
Microsoft SharePoint Foundation 2010:
- KB 2028568 – Download
Microsoft SharePoint Server 2010:
- KB 983319 – Download
- KB 983497 – Download
- KB 2182938 – (localized Japanese only) – Download
- KB 2281364 – Download
- KB 2124512 – Download
The KB articles for these fixes are not yet online but should become available in the next days.
After installing the fixes you need to run the SharePoint 2010 Products Configuration Wizard on each machine in the farm.
