I’ve been looking for official links to all SharePoint service pack and version history information for some time and have only been able to find various blogs out there, none of which are updated regularly.  Fortunately, Microsoft actually does have official pages for updates and service packs.  Here are the links (mostly so I don’t lose them again 😉 )

Official Microsoft Pages

• SharePoint 2013 and 2010
• SharePoint 2007 (Microsoft has removed this page)

There is also an RSS Feed for updates to all office products that includes all version of SharePoint, among other things.

Microsoft also has pages that show all of the specific version numbers for SharePoint by Product/Service Pack/Cumulative Update and, best of all, they are current as of this writing – including the August 2013 Cumulative Update.

• SharePoint 2013
• SharePoint 2010
• SharePoint 2007 (up to SP3).  SP3 and beyond is here.

Hopefully these will help more people than just me as these official pages were never near the top of my Google searches for any SharePoint topic and were hard to find if you weren’t searching on just the right keywords.

Update 09-Sep-2013 – Added links for SharePoint 2013 and revised text to reflect the changes
