The following regressions were found after this version was released. We recommend downloading the 8.4.1 release (when it'll be available).

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

This version brings a lot of usability improvements. The WYSIWYG editor (CKEditor) has been upgraded and proposes a better dialog for the creation of links. It is also possible to configure it from the administration.

Application Within Minutes does not enforce anymore the location where the application's entries must be created, but proposes to the creator the places where and from where these entries should be. We have also get rid of the Data page where the entries where created before.

The default values of the user preferences are now better exposed to the users. The order of the applications in the application panel can now be changed by the administrator. And the users now have the ability to filter the page types when they create a page.

As usual plenty of less noticeable improvements are proposed, and 45 bugs have been fixed since XWiki 8.3.

Backward Compatibility and Migration Notes

General Notes

When upgrading make sure you compare your xwiki.cfg, xwiki.properties and web.xml files with the newest version since some configuration parameters may have been modified or added. Note that you should add xwiki.store.migration=1 so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.
