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.

This release mostly focused on adding the ability to Like pages and changing the way to add a new comment. As usual it also fixes bugs and adds some other minor features.

New and Noteworthy (since XWiki 12.6.1)

Full list of issues fixed and Dashboard for XWiki 12.7.

For Users

Page Likes

 
The Page Like feature allows users to Like pages. By default, this application adds a small button at the bottom of the pages, allowing users to like them. It also displays the total number of likes for the page. Notifications are sent when pages are Liked and it's possible to see your own liked pages or who liked a page.

Comment form not displayed by default

 
The comment form is now hidden by default. This allows improving the loading performance of XWiki pages and makes the UI less cluttered.

A button allows you to display the comment form when you need to add a new comment.

For Admins

• Add a Solr store for ratings: It is now possible to store Ratings information in a Solr core: this should improve the scalability of the extension. Please note that the migration of data from one store to another is not yet supported.

For Developers

Allow to define a default XAR entry type when building XARs

 
Added the option <defaultEntryType>myEntryType</defaultEntryType> in the configuration of the XAR plugin when building XAR artifacts.

When defined, the default enty type will be applied to every entry not being overridden through the <entries>...</entries> list in the plugin configuration.

See the Maven XAR Plugin documentation for more information about this feature.

Miscellaneous

• Non-minified Javascript: Non-minified versions of JavaScript files are now also bundled by default in XWiki. This makes it much simpler to debug JavaScript issues in production. Just look for the non-minified (source) code using the developer tools provided by the browser. Since the minified code indicates the source map and the source map indicates the source file, the browser ends up loading all 3 (when the developer tools are open). If you can't find the source code then you can force the browser to load it by reloading the current page with ?minify=false in the URL.

• 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.
