The following new PSR-14 events have been introduced: - :php:`TYPO3\CMS\Core\Package\Event\PackagesMayHaveChangedEvent` - :php:`TYPO3\CMS\Core\Package\Event\AfterPackageActivationEvent` - :php:`TYPO3\CMS\Core\Package\Event\AfterPackageDeactivationEvent` - :php:`TYPO3\CMS\Core\Package\Event\BeforePackageActivationEvent` - :php:`TYPO3\CMS\Extensionmanager\Event\AfterExtensionDatabaseContentHasBeenImportedEvent` - :php:`TYPO3\CMS\Extensionmanager\Event\AfterExtensionStaticDatabaseContentHasBeenImportedEvent` - :php:`TYPO3\CMS\Extensionmanager\Event\AfterExtensionFilesHaveBeenImportedEvent` - :php:`TYPO3\CMS\Extensionmanager\Event\AvailableActionsForExtensionEvent` They replace the existing Extbase-based Signal Slots: - :php:`PackageManagement::packagesMayHaveChanged` - :php:`TYPO3\CMS\Extensionmanager\Utility\InstallUtility::afterExtensionInstall` - :php:`TYPO3\CMS\Extensionmanager\Utility\InstallUtility::afterExtensionUninstall` - :php:`TYPO3\CMS\Extensionmanager\Utility\InstallUtility::afterExtensionT3DImport` - :php:`TYPO3\CMS\Extensionmanager\Utility\InstallUtility::afterExtensionStaticSqlImport` - :php:`TYPO3\CMS\Extensionmanager\Utility\InstallUtility::afterExtensionFileImport` - :php:`TYPO3\CMS\Extensionmanager\Service\ExtensionManagementService::willInstallExtensions` - :php:`TYPO3\CMS\Extensionmanager\ViewHelper\ProcessAvailableActionsViewHelper::processActions` Impact ====== It is now possible to add listeners to the new PSR-14 Events which define a clear API what can be read or modified. The listeners can be added to the :file:`Configuration/Services.yaml` as it is done in TYPO3's shipped extensions as well. .. index:: PHP-API, ext:core
