Release Notes for XWiki 15.10.2

Last modified by Pierre Jeanjean on 2024/02/09

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 bug fix release is the first Long Term Support release of the 15.x cycle. It includes fixes for regressions that were reported for XWiki 15.10.1 and security fixes.

The following regressions were introduced in this release (and found after it was released). Please check them out and if they impact you we recommend waiting to upgrade to a version where they are fixed.

New and Noteworthy (since XWiki 15.10.1)

Full list of issues fixed and Dashboard for XWiki 15.10.2.

For Developers

  • New API to safely evaluate XObject properties: A new API to provide safe evaluation of XObject properties has been introduced to allow developers to control which properties from which XClasses should be evaluable, and how they should be evaluated. For XObjects that have assigned evaluators, the evaluated properties can be recovered in scripts through the new evaluate() method.

Known issues

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.

API Breakages

The following APIs were modified since XWiki 15.10.1:

Unstable APIs

Not real backward compatibility breakages since they were done on APIs marked @Unstable (a.k.a Young APIs). Thus it's part of the contract that they can be broken until they become stable. They're listed purely for reference in case you decided to still use them (and thus agreed to be broken).

  • Unstable API. The Optional wrapper proved to be useless.
    • Violation type:
    • Code:
      ## Old:
      method java.util.Optional<> throws

      ## New:
      method throws
