Full list of issues fixed and Dashboard for XWiki 5.4.

Distribution Wizard improvements

The upgrade mode has been removed, instead both modes are kind of enabled: it's always proposed to upgrade subwikis from main wiki and the Distribution Wizard is also always enabled on sub-wikis and displayed only if there is something to do.

  • <list libraries that have been upgraded>


  • We added a new parameter to the Live Table Velocity macro named 'selectedTags' which controls the list of tags that are selected initially in the tag cloud. You can still select different tags after the live table loads. With this new parameter you can have a permanent link to a live table that has the rows filtered initially by some tags:
    ## /xwiki/bin/view/Demo/WebHome?tag=news&tag=science
    #set ($options = {
      'className': 'Demo.DemoClass',
      'tagCloud': true,
      'selectedTags': $request.getParameterValues('tag'),
  • The module xwiki-platform-wiki-rest replaces the old module xwiki-platform-wiki-manager-rest in order to move xwiki-platform-wiki-manager in contrib, but the API is unchanged.
  • Verbosity of the job is now configurable right from the org.xwiki.job.Request object
  • Log generator now generates BeginEvent/EndEvent variants based on marker informations
  • The following java.lang.Class methods are now allowed in Velocity by default: name, isArray, isAssignableFrom, isEnum, isInstance, isInterface, isLocalClass, isMemberClass, isPrimitive, isSynthetic
  • Default job status does not provide log tree anymore. Was making the API too complex. It can be created from the log queue very easily in Java and a helper method has been added in logging ScriptService to create one: $services.logging.toLogTree($logs)
  • Various APIs have been added to help translate log. See Logging Module for more details.

General Notes

When upgrading make sure you compare your xwiki.cfg, and web.xml files with the newest version since some configuration parameters may have been modified or added. Note that you should add so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.
