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 is a minor milestone release that adds new template provider restrictions, improved support for the WildFly application server, default support for Let's Encrypt certificates and 26 additional bugfixes which contribute to stabilizing XWiki.

New and Noteworthy (since XWiki 8.3 Milestone 1)

Full list of issues fixed and Dashboard for 8.3.

For Users

Document Tree Improvements

 
The tree now displays the rendered translated page title when the showDocumentTitle parameter is set to true, which is the default value. So the document tree is now taking into account the current locale when displaying the page titles. Moreover, the child pages are now sorted by their raw translated title, with a fall-back on the raw default title and then on the page name (if the raw titles are empty). Note that the rendered title may be different than the raw title if the title is dynamic (i.e. has Velocity code) so the child pages may not be sorted correctly if some have dynamic titles. The child pages are sorted by their name when the showDocumentTitle parameter is set to false.

The support for relative references in the root and openTo parameters has been improved. You still need to prefix the entity reference with its entity type though.

{{documentTree root="document:Alice" openTo="document:Bob" /}}

The behavior of the limit parameter has changed a bit: if there is only one child node remaining the "more ..." link is replaced by that child node, instead of displaying "one more".

The child nodes should be loaded much faster now as we refactored and improved the database queries used under the hood.

Improved Not Found Screen

 
Added partial matches for the Document/Attachment Does Not Exist suggestions, in addition to the existing stemmed and fuzzy matches, for better results.

We were previously searching using indexed Solr data (stemmed) and also using fuzzy searches (string difference of 2; helps with minor typos), but this did not cover partial matches. Example: "Sandb" is matched by the fuzzy search, since it has a difference of 2 characters ("ox"), but "Sand" is not matched by anything (no stemming and too greater string difference - 3).

For Admins

Template Restrictions

 
It's now possible to specify visibility restrictions separate from creation restrictions on a template provider and to set default values. See the documentation for more details.

Miscellaneous

For Developers

  • Added an order field to the "After Header" extension point.

  • The Velocity #try() directive now accepts an optional parameter to specify the name of a Velocity variable into which to save the caught exception. For example:

    {{velocity}}
#try("myexception")
$services.query.xwql("zzzzz").execute()
#end

#if ($myexception != '')
  ... do something...
#end
{{/velocity}}

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.

API Breakages

No API has been broken since XWiki 8.2.1.
