This release enables realtime WYSIWYG editing by default and contains a number of smaller improvements and bug fixes.

New and Noteworthy (since XWiki 16.8.0)

Full list of issues fixed and Dashboard for 16.9.0.

For Users

Realtime WYSIWYG Editing Enabled by Default

 
Realtime editing is now enabled by default when editing the content of a wiki page using either the in-place or the standalone WYSIWYG editor. We encourage you to test it and report any issues you may find so that we can fix them before the new LTS version (16.10.x). For more information about the realtime WYSIWYG editor, including its limitations, please check the documentation.

Incoming link updates wait for indexing

 
When updating links as part of renaming or copying a document or attachment, the operation now waits for link indexing to complete. This waiting can optionally be skipped after ten seconds. For details, see the documentation about link indexing.

  • xwiki.cfg
  • xwiki.properties

Issues specific to XWiki 16.9.0

Realtime WYSIWYG Editing

The default WYSIWYG editor (CKEditor) configuration has changed to enable realtime editing: the xwiki-realtime CKEditor plugin has been removed from the list of disabled plugins. If you're upgrading an XWiki instance where the CKEditor configuration has been customized then you need to enable the realtime editing yourself, if you want to use it, by removing the xwiki-realtime CKEditor plugin from the list of disabled plugins.

API Breakages

The following APIs were modified since XWiki 16.8.0:
