The SharePoint 2010 product family cumulative updates are available now for download. Here is the links of the CUs:
- SharePoint Foundation 2010 Feb 2011 CU.
- SharePoint Server 2010 Feb 2011 CU.
- SharePoint Server 2010 with Project Server Feb 2011 CU.
Note that the SharePoint Server CU contains also the SharePoint Foundation CU, so there is no need to install both of them if you plan to update your SharePoint Server.
The KB articles are not released at this moment, i will update this post when they are available.
