+----------------
+
+Support for PHP 8.0 removed
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In this release support for PHP 8.0 was removed. Follow the steps below to make your app compatible.
+
+1. If ``appinfo/info.xml`` has a dependency specification for PHP, increase the ``min-version`` to 8.1.
+
+.. code-block:: xml
+
+  <dependencies>
+    <php min-version="8.1" max-version="8.3" />
+    <nextcloud min-version="27" max-version="30" />
+  </dependencies>
+
+
+2. If your app has a ``composer.json`` and the file contains the PHP restrictions from ``info.xml``, adjust it as well.
+
+.. code-block:: json
+
+  {
+    "require": {
+      "php": ">=8.1 <=8.3"
+    }
+  }
+
+3. If you have :ref:`continuous integration <app-ci>` set up, remove PHP 8.0 from the matrices of tests and linters.
