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.

This release focused on fixing bugs on Notifications, Office Viewer and Solr Search. User preferences are now taken into account by the notifications toggles.

New and Noteworthy (since XWiki 9.8.1)

Full list of issues fixed and Dashboard for 9.9.

For Users

Watched Locations Enhanced

 
The notifications toggles now take into account the preferences that you have enabled. Events that have not been enabled first will not be displayed anymore, even if you watch a location where these events happen.

For Admins

No changes!

For Developers

The server is now able to check for its new versions

 
The server can now check if a new version of its distribution is available but this feature is not active by default and the information about new versions are not displayed anywhere yet. In the near future, we'll add a new notification visible to administrators when a new version is found.

The version check can be enabled through the parameter extension.versioncheck.environment.enabled in xwiki.properties.

Backward Compatibility and Migration Notes

General Notes

When upgrading make sure you compare your xwiki.cfg, xwiki.properties and web.xml files with the newest version since some configuration parameters may have been modified or added. Note that you should add xwiki.store.migration=1 so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.

Issues specific to XWiki 9.9

• JSONTool#parse is now deprecated and JSONTool#fromString should be used instead. This means that Velocity code like $jsontool.parser($content) should be replaced by $jsontool.fromString($content)
