Last week, Autodesk released their first patch to the 2013 Revit products.  This is for all versions of Revit including the suites.  Here is a link to the release http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=20121970&linkID=9273944 .  I know that a lot of folks have been waiting for this release before they upgraded their projects to 2013.  In the release notes  it seems that most of the issues that have been bugging people has been fixed.  We are deploying the release today and will see if there are any lingering issues after the deployment.  Here is a link to the release notes as well, http://images.autodesk.com/adsk/files/enhancements_list_rac_2013_ur1.pdf .
