+Breaking: #21638 - AbstractUserAuthentication::lockIP property removed
+======================================================================
+
+See :issue:`21638`
+
+Description
+===========
+
+The IP-locking-functionality is extended from IPv4 only to now also support IPv6. A separate IpLocker-functionality was added.
+
+The public property :php:`lockIP` in :php:`TYPO3\CMS\Core\Authentication\AbstractUserAuthentication` is now removed.
+It usually shouldn't have been accessed directly and supported IPv4 only.
+
+
+Impact
+======
+
+Extensions relying on :php:`lockIP` won't be able to perform their task anymore.
+This might for example be the case when :php:`lockIP` was set dynamically, depending on the REMOTE_ADDR.
+
+
+Affected Installations
+======================
+
+Every 3rd party extension depending on the formerly public :php:`lockIP` property is affected.
+
+
+Migration
+=========
+
+Set :php:`lockIP` and :php:`lockIPv6` in :php:`TYPO3_CONF_VARS` - for FE or BE depending on the use case.
+Use the new :php:`\TYPO3\CMS\Core\Authentication\IpLocker` API.
