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.

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);
