Microsoft releases SP1 and here are the release notes – that have been anticipated for while now.

They are mostly bug fixes and performance tweaks, but the sheer volume of them is certainly something to behold.

SP1 includes 23 security updates and 550 hotfixes resulting in a 434.5MB download (726.5MB for the 64-bit version).

SP1 is available for download now via Microsoft’s sites, with an auto-update rollout scheduled for next month
