+===============================================
+Deprecation: #47712 - Deprecate old Locking API
+===============================================
+
+See :issue:`47712`
+
+Description
+===========
+
+The old class `\TYPO3\CMS\Core\Locking\Locker` has been marked as deprecated.
+
+The configuration option `[SYS][lockingMode]` is now marked as deprecated and only affects the old Locker class, which is
+unused in the Core now.
+
+Moreover two unused methods of `\TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController` have been marked as deprecated:
+
+* acquirePageGenerationLock()
+* releasePageGenerationLock()
+
+
+Impact
+======
+
+Using the old class will trigger deprecation log messages.
+
+
+Migration
+=========
+
+Use the new Locking Service API instead.
