*** Update *** see http://blogs.msdn.com/brismith/archive/2010/03/09/office-servers-february-cu-and-the-project-server-database-versions-table.aspx for information regarding the db versions table - no db updates in this project Server CU, so no new number in the versions table. If you hadn't already loaded the Dec CU then the version will change to December's.
Full details, see the Admin blog at http://blogs.technet.com/projectadministration/archive/2010/02/26/february-2010-cumulative-update-cu-for-project-server-2007-office-sharepoint-server-2007-wss-and-project-2007-now-available.aspx
There were also a few fixes that just missed incorporation in the CU, but are also available – from the Admin blog:
Note: There has been a follow-up CU build that was released just after the February CU. This CU contains three fixes that are not included in the February CU. Please check http://support.microsoft.com/kb/980854 to see if these are fixes you need. This CU also contains all of the fixes in the February CU so you will not need to install the February CU if you install this fix unless you are a Microsoft Office SharePoint Server (MOSS) user. Customers running MOSS will want to install the server rollup fixes and then the post-February CU. This CU will not be downloadable from the KB so you will need to open a Support Case in order to obtain it. Customers with existing cases open for the February CU do not need to open another case.
As always, there can be delays in the KB’s and if you need the downloads the ‘secret’ is to substitute the desired KB number into the following URL - http://support.microsoft.com/hotfix/KBHotfix.aspx?kbnum=XXXXXX&kbln=en-us.
