This is the release notes for XWiki Commons, XWiki Rendering and XWiki Platform. They share the same release notes as they are released together and have the same version.

The main focus of this release is stabilization. In addition, a new UI is now proposed to administrate the rights that are provided by extensions. On a final note, more Livetables are migrated to Live Data and a few improvements are proposed to developers.

The following regressions were introduced in this release (and found after it was released). Please check them out and if they impact you we recommend waiting to upgrade to a version where they are fixed.

New and Noteworthy (since XWiki 13.4)

For Admins

New administration section for Extension Rights

A new administration section has been introduced allowing to display and set the extension rights: those are rights that some specific extensions might provide, and which are not part of the core rights. By default in XWiki Standard, the Like Right is displayed in there since it's part of the Like extension which is automatically installed.

For Developers

  • History delete event: It's now possible to be notified when a range of document history versions is deleted using the event org.xwiki.bridge.event.DocumentVersionRangeDeletedEvent. See Model Bridge API for more details.

  • New API to unregister a custom right: It was already possible to register a custom right, but we were missing the API to unregister it, this is now possible in the AuthorizationManager API.

Backward Compatibility and Migration Notes

General Notes

  • When upgrading make sure you compare and merge the following XWiki configuration files since some parameters may have been modified, removed or added:
    • xwiki.cfg
    • web.xml
    • hibernate.cfg.xml
  • Add in xwiki.cfg so that XWiki will attempt to automatically migrate your current database to any new schema. Make sure you backup your Database before doing anything.

Like Right moved to Extension Rights section

As explained in this dedicated release change, a new administration section has been provided for Extension Rights, and the Like rights should now be configured in there. So the Like right won't appear anymore in the Rights section of Administration, but all settings are kept as they were.
