As Stefan just posted on his blog the first CU for SharePoint 2010 is now available for download, if you are planning to install 983497 for SPS 2010 make sure to install 2281364 or you will get the following error when trying to open UPA management page:

Application error when access /_layouts/ManageUserProfileServiceApplication.aspx, Error=Could not load file or assembly 'Microsoft.ResourceManagement, Version=4.0.2450.9, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
