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 brings a new date picker and various merge improvements. Developers will also be able to reuse the standard color picker and the merge API give more details about the conflicts.

Some important bugs have been found since XWiki 11.7 has been released:

New and Noteworthy (since XWiki 11.6.1)

For Users

Improved Date Picker

The Date picker used to edit date properties has been improved. The new version is better integrated with the Bootstrap-based Flamingo skin and its UI adapts better to the provided date format configuration (e.g. by hiding UI elements that don't make sense). Checkout the Date Time Picker documentation for more information.

For Admins

No changes!

For Developers

Color Picker

The color picker used by the Flamingo Theme Application can now be re-used thanks to a new Velocity macro:

#set ($colorPickerParams = {
  'name': 'color',
  'value': '#85d4a9'

Checkout the Color Picker documentation for more information.

Date Time Picker

A new Velocity macro is available to create a date & time picker:

#set ($dateTimePickerParams = {
  'name': 'date',
  'data-format': 'dd/MM/yyyy HH:mm:ss'

Checkout the Date Time Picker documentation for more information.


  • Allow to perform custom decisions in case of merge conflict: The Diff module now offers new APIs to enhance the 3-way merge operation. The MergeResult is now capable of returning a list of Conflict objects which gives some information about the conflicts that occurred during the merge. Those conflicts can be solved on a case-by-case basis by specifying some ConflictDecision in the MergeConfiguration that is passed to the merge operation.

    The main goal here is to allow more fine-grained conflict resolution when performing a merge operation.

  • Display conflict information inside unified diff: The display diff API allows to display information about conflicts.
    The APIs to build unified diff takes as input a list of conflict elements that have been computed during a merge: some conflict information are then available in the resulting unified diff blocks, and can be used to present conflicts and possible decisions inside an UI presenting unified diff.

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
    • web.xml
    • hibernate.cfg.xml
  • Add 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 11.7

  • If you're upgrading from a version older than 11.4:
    • If you're upgrading XWiki you have to delete the 'solr' folder from the configured permanent directory of your XWiki instance in order for the Solr search to work. We upgraded Apache Solr in this release and this brought changes to the Solr schema and configuration files, which are cached in the 'solr' folder. Unfortunately we don't have support for automatic Solr search index migration at this point. The Solr index will be deleted as a result but it will be recreated automatically and the entire wiki will be re-indexed after a server restart.

API Breakages

No APIs were modified since XWiki 11.6.1.
