The rest of the update addresses various bugs, including an issue where file names would change when saved to SkyDrive or SharePoint in Microsoft Word for Mac. The font Calibri Light was also added, fixing poor rendering of Office 2013 shared documents that used the font.
Other bug fixes include being able to coauthor a PowerPoint Web App session without being alerted to potential conflicts, an expiring token notification, and an issue where keyboard and mice commands would "lose control" during a PowerPoint for Mac slideshow. A full list of bug fixes can be found on the Microsoft Support site.
While Office 2011 for Mac is still being updated, a new version of Office for Mac may arrive in April 2014. This update to Office 2011 for Mac, which requires Mac OS X 10.5.8 or later, is available for free via Microsoft AutoUpdate or Microsoft's website.
