New Deprecations

Developer Note

Since this version of Joomla has not been released yet, this page can change anytime.

All the new deprecations you should be aware of — and what you should use instead.

Class deprecations​

Planned to be removed in Joomla! 7.0.

Deprecation of UCM system​

In Joomla 3.2, the Unified Content Model was introduced, which was supposed to be a universal system for all content in Joomla. The concept turned out to be not viable and the remnants of this have now been deprecated for removal in Joomla 7.0. The following classes have been deprecated without replacement:

  • Joomla\CMS\Table\Ucm
  • Joomla\CMS\UCM\UCM
  • Joomla\CMS\UCM\UCMBase
  • Joomla\CMS\UCM\UCMContent
  • Joomla\CMS\UCM\UCMType

Deprecation of registerListeners()​

43395 – CMSPlugin: deprecation for registerListeners

  • ❌ registerListeners() is deprecated in both Joomla\CMS\Extension\PluginInterface and Joomla\CMS\Plugin\CMSPlugin.
  • ✅ Instead, implement the SubscriberInterface. The method is no longer required in this case.

Deprecation of $_db, getDbo(), and setDbo()​

45165 – Replace table _db with DatabaseAwareTrait

  • ❌ Do not access the Joomla\CMS\Table\Table::_db property directly — it will be removed in the future.
  • ❌ Avoid using the getDbo() and setDbo() methods — they will also be removed.
  • ✅ Use getDatabase() and setDatabase() instead. Sample: 
    $db = $this->getDatabase();
    $this->setDatabase($db);

Language String Deprecation​

Planned to be removed in Joomla! 6.0 is the language string:

  • 45564 – Deprecate language string
    • ❌ COM_JOOMLAUPDATE_VIEW_DEFAULT_UPDATES_INFO_TESTING
