 #### Optimistic Locking
             
-* We made optimistic locking publicly available as a beta feature. This allows apps to safe-guard for concurrent modifications. It can be enabled in the Runtime tab of the project settings dialog. Enabling this feature gives each entity an extra system attribute (`MxObjectVersion` of type `Long`). Its behavior will be automatically handled by the system. More details can be found in the documentation: http://docs.mendix.com/refguide/optimistic-locking.
