         - synchronization.allowDeletions parameter introduced
         - default value is true (existing behaviour)
         - when false, no missing users or groups are deleted from the repository
         - instead they are cleared of their zones and missing groups are cleared of all their members
         - colliding users and groups from different zones are also 'moved' rather than recreated
         - unit test added
      36491: Added CIFS transact2 NT passthru levels for set end of file/set allocation size. ALF-13616.
      Also updated FileInfoLevel with the latest list of NT passthru information levels.
      36497: Fixed ALF-14163: JavaScript Behaviour broken: Node properties cannot be cast to java.io.Serializable
       - Fallout from ALF-12855
       - Made class Serializable (like HashMap would have been)
       - Fixed line endings, too
      36531: ALF-13769: Merged BELARUS/V3.4-BUG-FIX-2012_04_05 to V3.4-BUG-FIX (3.4.10)
         35150: ALF-2645 : 3.2+ ldap sync debug information is too scarce 
            - Improved LDAP logging.
      36532: ALF-13769: BRANCHES/DEV/BELARUS/V3.4-BUG-FIX-2012_01_26 to V3.4-BUG-FIX (3.4.10)
         36461: ALF-237: WCM: File conflicts cause file order not to be consistent
            - It is reasonable set values for checkboxes using the indexes from the list, which are not changed. So when we submit the window, the getSelectedNodes method is invoked and 
              it takes selected nodes by checkbox values from "paths" list. 
      36535: Merged DEV to V3.4-BUG-FIX
         36479: ALF-8918 : Cannot "edit offline" a web quick start publication
            A check in TaggableAspect.onUpdatePropertiesOnCommit() was extended to skip the update, if no tags were changed.

      36388: ALF-14025: Updated Surf libs (1071). Fixes to checksum-disabled dependency handling
      36392: ALF-14129 Failed to do upgrade from 3.4.8 to 4.0.2
         << Committed change for Frederik Heremans >>
         - Moved actual activiti-tables creation to before the upgrade
      36409: Fix for ALF-14124 Solr is not working - Errors occur during the startup
      36466: Fix for ALF-12770 - Infinite loop popup alert in TinyMCE after XSS injection in Alfresco Explorer online edit.
      36501: Merged DEV to V4.0
         36496: ALF-14063 : CLONE - Internet Explorer hangs when using the object picker with a larger number of documents

      36541: ALF-14082: Input stream leaks in thumbnail rendering webscripts
      36560: Correctly size content length header after HTML stripping process (ALF-9365)
