OpenText has just released eDOCS DM 5.3. There are a whole raft of enhancements in the latest version of the OpenText DMS however probably the most important one is support for Microsoft Office 2010, whereas Autonomy iManage is not expected to deliver Office 2010 support until next year.
 
OpenText say the integration between eDOCS DM and Microsoft Office has been enhanced to give users the ability to customize their DMS experience by creating their own Microsoft Office Ribbons. This new functionality allows users to create custom Ribbons and include DM actions in them or add DM actions to their Quick Access Toolbar using standard Microsoft Office configuration options. In addition, support has been added for the new Microsoft Backstage interface to help users work with their documents. The Microsoft Word compare and merge integration has also been enhanced to allow users the ability to select from the default Comparison settings.

There are more details available on the attached PowerPoint deck.
