Release Notes for XWiki 15.4-rc-1

Last modified by Ilie Andriuta on 2023/07/12

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 mostly a bugfix release that includes important security bug fixes. It also contains some minor improvements for users and developers.

New and Noteworthy (since XWiki 15.3)

Full list of issues fixed and Dashboard for 15.4.

For Users

Available macros sorted by id

The available macros list is now sorted by ascending macro ids.


  • Added keyboard support for the like button.

  • Added keyboard support for the quick search suggestions.

  • TOC macro numbered property : The numbered property of the Table of Content macro is now marked as advanced and is only proposed in the "more" section of the macro configuration dialog. This is because we're now offering a Numbered Content Application covering the numbering use case in a better way.

For Admins

No changes!

For Developers

  • Anchor in EntityResourceReference: The anchor metadata has been added to EntityResourceReference, to align it with other entity reference-related APIs. The general goal is to be able to support anchors (a.k.a URL fragments) in references to resources.

  • Component role type priority: It's now possible to indicate the priority of a component among its role type siblings when it's retrieved through APIs like ComponentManager#getInstanceList and ComponentManager#getInstanceMap. In a Java component declaration, this is done through the standard javax.annotation.Priority annotation.

    Note that component priority can also be used to sort event listeners.

Security Issues

Known issues

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.

Issues specific to XWiki 15.4-rc-1

Mail Configuration

When overriding mail configuration in a subwiki, the credential values (username and password) don't fall back to the main wiki or to the file if the SMTP host has been overriden for that subwiki. This allows to have different SMTP credentials in subwikis than in the main wiki. Thus, if you were overriding the SMTP host in a subwiki and that it was using the same credentials than the ones defined in the main wiki (for example), you'll need to also override them now. 

API Breakages

The following APIs were modified since XWiki 15.3:

No breakage!
