Following the release of Office 2013 earlier today, Microsoft has released an update for Microsoft Office for Mac 2011. In addition to resolving several outstanding bugs in the application, Office for Mac 2011 is now also available on a subscription basis in Microsoft's Office 365 offering and requires OS X 10.5.8 or greater, an increase in the system requirements since the last version, and Office upgraded to 14.2.3 before application of the 14.3 patch.
