+Breaking: #76802 - Drop xcache cache backend
+============================================
+
+See :issue:`76802`
+
+Description
+===========
+
+The `xcache` core cache backend has been dropped because PHP7 does no longer support xcache.
+
+
+Impact
+======
+
+Instances will throw an exception or a fatal error using a cache with this backend configured.
+
+
+Affected Installations
+======================
+
+Instances that still use a configuration in :file:`LocalConfiguration.php` or :file:`AdditionalConfiguration.php` like:
+
+.. code-block:: php
+
+    'SYS' => [
+        'caching' => [
+            'cacheConfigurations' => [
+                'aCache' => [
+                    'backend' => 'TYPO3\\CMS\\Core\\Cache\\Backend\\XcacheBackend',
+
+
+Migration
+=========
+
+Affected instances must switch to a different cache backend, `APCU` `PHP` module with `ApcuBackend`
+provides the same local server in memory characteristics like `xcache` and should be considered as alternative.
