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.

This is a bugfix release that covers important issues that we have discovered since 12.6.1 has been released. In addition, a little improvement has been added on the comment section on the bottom of the pages, avoiding to load the "add comment" form when not needed.

New and Noteworthy (since XWiki 12.6.1)

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
    • xwiki.properties
    • web.xml
    • hibernate.cfg.xml
  • Add xwiki.store.migration=1 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.
