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.

Apart from bug fixes and dependency upgrades, this release contains several migrations to Live Data, offering an updated look and feel and more advanced filtering and sorting capabilities in more places in XWiki.

New and Noteworthy (since XWiki 16.0.0)

Full list of issues fixed and Dashboard for 16.1.0.

For Users

Documents macro migrated to Live Data

 
The documents macro is now using a Live Data (vs a LiveTable previously). Consequently, the Page index and the Space Index are now displayed with Live Data.

System filters migrated to Live Data

 
Notification system filters are now migrated to Live Data, both for the default configuration in the administration, and in the user profiles.

Custom filters migrated to Live Data

 
Notification custom filters are now migrated to Live Data, both for the default configuration in the administration, and in the user profiles.

Miscellaneous

• Server-side image resizing disabled on PDF export: Images that are inserted from wiki syntax and have their width or height specified are by default resized on the server-side to reduce network traffic and speed up page load. This makes sense for page view, where zooming is not common, but it leads to poor quality images in PDF export, where zooming is very common. As a consequence we decided to disable the server-side image resize when a page is exported to PDF. This means the images displayed in that page will be included in their full size in the generated PDF. See the PDF Export Application for more information.

For Admins

No changes!

For Developers

• CSS3.0 parsing support: On some cases, CSS parsing is required server-side. Previously, on CSS 2.1 was supported. This is for instance used for image styles parsing.

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
  • xwiki.properties
  • web.xml
  • hibernate.cfg.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.

Issues specific to XWiki 16.1.0

• eventstream.uselocalstore and eventstream.usemainstore properties defined in xwiki.properties are now removed: events were already not using those values anymore, and now filters are also not using them, they're systematically stored in the same database as the owner of the filter.

API Breakages

No API breakage since XWiki 16.0.0.
