As expected, Microsoft has just released Office for Mac 2011 Service Pack 1. The update, which weighs in at 246.2 MB, addresses a number of bugs and security issues while also bringing several new features including a number of enhancements to Outlook.
Security updates with bug fixes also appear to be on the way for Office 2008 (12.2.9) and Office 2004 (11.6.3).
Availability of the software updates is currently sporadic, with download pages properly loading on an intermittent basis and the updates not yet showing in the AutoUpdate tool packaged with Office.
