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.

API Breakages

The following APIs were modified since XWiki 13.4.4:

Unknown Criticality

These violationq are missing a criticality and need to be fixed.

  • Not a breakage, the old XWikiContextInitializationFilter content has been moved to a new class of the same name in a new package and old class now inherits from the new one
    • Violation type:
    • Code:
      ## Old:
      class org.xwiki.wysiwyg.filter.XWikiContextInitializationFilter

      ## New:
      class org.xwiki.wysiwyg.filter.XWikiContextInitializationFilter
  • Unstable API: this method should not have been made public in first place, the cache clean is handled by listening on the events automatically.
    • Violation type:
    • Code:
      ## Old:
      method void
  • Has been deprecated for a long time.
    • Violation type:
