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.

New and Noteworthy (since XWiki 8.4.1)

Full list of issues fixed and Dashboard for 8.4.2.

For Users

CKEditor Integration Improvements

CKEditor has been upgraded to version 4.6.0 which brings a new flat skin and a lot of improvements and bug fixes. The XWiki integration has been improved to support automatic link creation when dropping a non-image file over the editing area. Creating a link to a non-existing wiki page has been simplified. Check the CKEditor Integration documentation for more information.

The "page type" picker is bigger

In order to better see the available page types (like Encyclopedia, Article, etc...), the "page type" selector has been enlarged.

For Admins

Localization Section

It's now easier to pick a time zone or a language in the "Localization" section of the Administration, thanks to a filter box.

For Developers

Backward Compatibility and Migration Notes

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.

API Breakages

No API has been broken since XWiki 8.4.1!
