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 our last stabilization release for the XWiki 7.x Cycle. It brings polishing and stabilization for the Nested Pages feature and the changes in UI that resulted from it, especially for the Watchlist.

New and Noteworthy (since XWiki 7.3)

Full list of issues fixed and Dashboard for 7.4.

Notifications & Watchlist

• A new menu has been added to the top bar, on the right: the "notifications" menu (represented by a bell). In the future, it will be the place where you can find notifications about some events happening on the wiki (personal message, a page has been modified, etc...).

  

• In this menu, we have moved the Watchlist icons (watch this page, watch this wiki, etc...). These actions can be triggered with the new switch buttons

  

Miscellaneous

• Some bootswatch themes have now a more accurate logo.
• When the search button on the top menu is clicked, it now closes all other menus.
• The Sandbox now uses the last XWiki 2.1 syntax.
• Non terminal pages are now exported with their corresponding WebPreferences page

For Developers

Tree Velocity Macros

You are now able to "call" the Document Tree from Velocity using something like this:

The same is possible with the generic Tree Widget:

All the parameters that are available for the wiki macros ({{documentTree}} and {{tree}}) should be available also for the corresponding Velocity macro.

New public Abstract job

A public org.xwiki.job.AbstractJob is now provided to help implementing a Job. An AbstractJob class already existed since a long time but it was in an internal package.

Miscellaneous

• An extension point to add content inside the new  "Notifications" menu has been added:

  org.xwiki.platform.notifications

• A new extractFirstReference(EntityType) API has been added to EntityReference: Extract the first entity of the given type from this one by traversing the current entity to the root. This differentiates it from extractReference(EntityType) which extracts the last entity of the given type.
• The escape Velocity tool has a new method to escape CSS identifiers. This is similar to CSS.escape() available in JavaScript, and is useful if you want to create CSS selectors dynamicaly using untrusted input.
  $escapetool.css('a#b.c d[e=f]g{h:i;j}k')
  ## Output: a\\#b\\.c\\ d\\[e\\=f\\]g\\{h\\:i\\;j\\}k
• The Document Tree Macro has a new parameter to control whether the hidden documents are filtered or not. Set to false to force the display of the hidden documents in the tree.
  {{documentTree filterHiddenDocuments="false" /}}

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 7.4 Milestone 1

• Better backward-compatibility for URLs has been added for the following 2 cases:
  • If the view action is omitted in the URL and the first space name doesn't match an action name, then the "view" action is implied
  • The view action can be specified even when the wiki is configured to hide the view action.
  • Note that this fixes some backward-compatibility issue introduced in XWiki 7.2

API Breakages

The following APIs were modified since XWiki 7.3:
