Lately I was (again) really considering letting go of my RSS subscription to the MSDN blogs and again, one single blog among so many, made me glad I didn't: Update 2 für Microsoft Dynamics NAV 5.0 SP 1 verfügbar by Sebastian Röttel/Microsoft Germany. This link will bring you directly to the right page on Partner Source. It appears you have to down load the whole DVD to get the Microsoft Dynamics NAV 5 0 SP1 Update 2 Release Notes. This update is called a Platform Update 2 which makes sense going through the release notes and is "... verified to run on Windows 7 and on Windows Server 2008 R2".
Funny that only Sebastian Röttel is keeping us updated in these kind of releases. Or am I blind to other info?
Apparently I was not blind but too fast. Late afternoon a NAV Team Blog was published on this here.
