=====================================================
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.
