Microsoft announced today that it will end support for Office 2008 for Mac on April 9.
Office for OS X has been a staple in integrating OS X systems with many work environments that rely on Microsoft's popular office productivity suite. With its Mac Business Unit, Microsoft has maintained a dedicated development team for its Mac software which has spearheaded development of Office 2004, 2008, and the latest 2011 and 365 offerings.
With this development, those who use Office 2008 will still be able to do so, but will not be able to get any official support for the program from Microsoft. Additionally, while no new patches for the software will be available after this date, current ones will continue to be available on Microsoft's site until April 19, 2014.
This announcement does not mean you have to upgrade your version of Office right away, but Microsoft is encouraging Office 2008 users to try Office 365, which comes with a subscription at $100 per year or $10 per month. In addition, Microsoft is offering its latest standalone Office 2011 suite for between $140 and $220.
Microsoft has not commented on its plans for Office 2011, but for now this suite continues to be fully supported.
