.. include:: /Includes.rst.txt .. _deprecation-85462-1668719172: ===================================================== Deprecation: #85462 - Signal 'hasInstalledExtensions' ===================================================== See :issue:`85462` Description =========== The usage of signal :php:`hasInstalledExtensions` of class :php:`\TYPO3\CMS\Extensionmanager\Service\ExtensionManagementService` has been marked as deprecated and will be removed in TYPO3 v10. The signal is a duplication of :php:`afterExtensionInstall` that is also emitted during extension installation. Impact ====== Slots of this signal will get executed in TYPO3 v9 but will be abandoned with TYPO3 v10. Affected Installations ====================== Extensions that register slots for the signal :php:`hasInstalledExtensions` of class :php:`\TYPO3\CMS\Extensionmanager\Service\ExtensionManagementService`. Migration ========= Extensions should use the signal :php:`afterExtensionInstall` of class :php:`\TYPO3\CMS\Extensionmanager\Utility\InstallUtility` instead which is emitted after an extension has been installed. .. index:: Backend, LocalConfiguration, PHP-API, NotScanned, ext:extensionmanager
