New and Noteworthy (since XWiki 5.2 Milestone 2)

Full list of issues fixed and Dashboard for 5.2.

Top Menus changes when there is more than one wiki

We have removed the XWiki right menu and created a "Home" menu instead.

Distribution Wizard Step to Upgrade All Wikis

We added a new step to the Distribution Wizard to update the default set of wiki pages on each of the existing wikis. This step is triggered only if you choose to upgrade the entire farm in the "Upgrade Mode" step.


Markdown Syntax 1.1

We've added version 1.1 of the Rendering Syntax for Markdown, adding support for:

  • Macros
  • Superscript and subscript
  • (X)HTML improvements

Export big wikis as XAR

It's possible to enable the use of new WikiStream framework in standard export action (use in the standard export UI for example). Among other things it allows exporting a wiki of pretty much any size.

WikiStream is too young for it to be enabled by default and will require heavy testing. In the meantime you can try it by uncommenting # xwiki.action.export.xar.usewikistream=1 at the end of xwiki.cfg file.


  • Improved Active Installs Server side API to be able to pass any query to count installs.
  • Active Installs Client now also send the Distribution id in addition to the Distribution version to identify the "product" sending the ping
  • The checkboxes for the global rights settings are now displayed on the left of their labels.


  • The live search (search suggest) now displays a message when there are no results.


  • The blog application is now packaged by default in the Home wiki only (not in new wikis).

Backward Compatibility and Migration Notes

General Notes

You may also want to import the default wiki XAR in order to benefit from all the improvements listed above.

Always make sure you compare your xwiki.cfg and files with the newest version since some configuration parameters were added. Note that you should add so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.
