Release Notes for XWiki 12.8-rc-1

Last modified by Thomas Mortagne on 2020/09/28

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.

Various usability improvements such as ability to skip the recycle bin, simpler unlike feature, more consistent menus.

New and Noteworthy (since XWiki 12.7)

Full list of issues fixed and Dashboard for 12.8.

For Users

Simplified Unliking

A modal was previously asking for confirmation for removing a like on a page. This has been removed to make it simpler and more consistent: liking and unliking are now both immediate actions.

View source in viewers menu section

The View source link has been moved to the Viewers menu sub-section of Other actions menu, to be consistent.

Mentions explained on the tips

The use of the mentions in WYSIWYG editor autocompletion is now explained on the tips.

View Likes in viewers menu section

The menu item for viewing Likes information has been moved to Viewers sub-section of the other options menu, for consistency.

New Comment button

The comments section at the bottom of pages used to have the comment editor visible. There's now a Comment button to click when wanting to add a comment. This was done for 3 reasons:

  • For consistency with other actions where you have to click a button to do them (annotate, edit, create, etc).
  • It makes the UI a bit less cluttered and avoids focusing the attention on comments which was very visible, especially since we moved to using the WYSIWYG editor by default in comments.
  • It also improves the loading performance of XWiki pages since the editor doesn't need to be loaded when viewing pages

For Admins

Option to skip the recycle bin

There's now an administration option to allow advanced users to choose whether deleted pages are sent to the recycle bin or not.

To do so, search for the "Delete" section in the Administration and set "can skip the recycle bin" to Yes. The default value is No to avoid unwanted loss of data.


Social category in Administration

A new Social category has been added in Administration to gather all configurations related to social features. Those items were previously all in the Other category.


For Developers

Targetable Events disregard Inclusive filters

We changed slightly the behaviour of Notification Filters for Targetable Events. These type of events are not concerned anymore by inclusive filters. It means that these events will be received by users even if the location where the event has been sent to is not watched by the user. This is useful for example for Mentions to allow receiving Mentions notifications from any location without needing to watch it.

Note that the exclusive filters are still honored by targetable events: this allows users to keep not receiving notifications on the chosen locations.


  • New UIXP for the viewers menu section: A new UI Extension Point has been created to be able to extend the Viewers sub-menu of "other options" menu.

  • Enable Strict Mode for JSX: XWiki can now be configured to parse and minify wiki-based JavaScript skin extensions (JSX) using strict mode. This is disabled by default but you can enable it from using:

    skinx.jsStrictModeEnabled = true

    Check the skin extension documentation for more information.

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.
