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 release introduces an experimental realtime Wiki editor (superseding the existing Realtime Collaborative Plain WikiText Editor contributed extension) and an experimental WYSIWYG editor (superseding the existing Visual Realtime Collaborative Editor contributed extension). They are not bundled yet in XWiki Standard but we plan to do this soon. For developers there's a new API available, called Netflux (superseding the existing Realtime Netflux Backend contributed extension), to write realtime-enabled extensions on top of XWiki.

New and Noteworthy (since XWiki 13.8)

Full list of issues fixed and Dashboard for 13.9.

For Users

Experimental Realtime Wiki Editor

 
We cleaned up the Realtime Collaborative Plain WikiText Editor contributed extension and integrated it in the XWiki platform. It's not bundled yet in XWiki Standard but you can still try it out by installing it and following the documentation page.

Experimental Realtime WYSIWYG Editor

 
We cleaned up the Visual Realtime Collaborative Editor contributed extension and integrated it in the XWiki platform. It's not bundled yet in XWiki Standard but you can still try it out by installing it and following the documentation page.

For Admins

No changes!

For Developers

Realtime Communication (Netflux)

 
The new Netflux module provides support for real-time WebSocket-based communication in XWiki by offering:

• a script service and a REST resource to help create and retrieve communication channels.
• a WebSocket server end-point used to join channels and to exchange channel or direct user messages.

This can be used along with the Netflux Client to implement realtime-enabled extensions on top of XWiki (e.g. a chat application).

Miscellaneous

• New event query helper: SimpleEventQuery now have helpers to manipulate custom event properties. It's done by calling parameter() to "switch" the next comparison to be about custom parameters instead of standard Event fields. See Event Stream Module for more details.

• 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

• 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.
