Service packs may have gone out of style in the Windows realm, but they're still alive in Office.
On July 23, Microsoft made available Office 2010 and SharePoint 2010 Service Pack 2. (The downloads, which are gradually showing up as of this morning on the Microsoft Download Center, are marked as having been published on July 21.)
Microsoft delivered the betas of Service Pack 2 for Office 2010 and SharePoint 2010 back in early April of this year. (Invites for a private preview of Office 2010 SP2 went out in mid-January.)
As was the case with the beta, the final SP2 is a rollup of all previously released updates to Office 2010.
Microsoft officials said in April that SP2 consists of updates that improve security and compatibility. Specifically, SP2 provides improved compatibility with IE 10, Windows 8, Windows Server 2012 and Office 2013.
Microsoft also is releasing an SP2 for its Office Web Apps today. Office Web Apps are the Webified versions of Word, Excel, PowerPoint and OneNote that Microsoft makes available for free and for use in various browsers on Windows, Mac OS and Linux.
Update: Here's the Office Sustained Engineering blog which includes links to all the various Office 2010 SP2 downloadables.
