The long awaited service pack for PerformancePoint Server 2007 is now released to the web - Service Pack 3. This is the last service pack for PerformancePoint Server since the PerformancePoint Server bits will from next week be turned into PerformancePoint Services in SharePoint 2010.
Service Pack 3 is the last update to the standalone version of PerformancePoint, which was announced in January this year when Microsoft changed their BI strategy. After this update Microsoft will not invest any further into the 2007 version and as you hopefully are aware of - the Planning module will not exist in the upcoming 2010 version. The Planning module is instead offered as source code - now called the Financial Planning Accelerator, so that you can safely still use any investments in the Planning Module.
You can grab the bits here: 32-bit and 64-bit. Documentation on the different upgrade scenarios can be found on Technet.
So far the KB (975250) article on what’s changed and updated is not live. Some things have popped up on Technet though, such as a updated importsecurity command.
