MicroStrategy 9.0 Hotfix 1 is now generally available (GA) on the MicroStrategy Download Site.
Defects and Enhancements addressed in MicroStrategy 9.0 Product Suite can be found in the ReadMe.
I’m wondering: Why this HotFix was released too close from the 9.0 launch?
A HotFix is a FIX! Therefore the 9.0 version was released with a number of bugs that had required this fast paced HotFix.
May I stay with my 8.x version or upgrade to 9.0?
Look close to MSTR 9.0 improvements and ask yourself if you need this upgrade. If no, then stay calm and wait for a second hotfix.
