-Airflow 2.7.3 (2023-11-04)
+Airflow 2.8.0 (2023-12-14)
+--------------------------
+
+Significant Changes
+^^^^^^^^^^^^^^^^^^^
+
+- Raw HTML code in DAG docs and DAG params descriptions is disabled by default
+
+  To ensure that no malicious javascript can be injected with DAG descriptions or trigger UI forms by DAG authors
+  a new parameter ``webserver.allow_raw_html_descriptions`` was added with default value of ``False``.
+  If you trust your DAG authors code and want to allow using raw HTML in DAG descriptions and params, you can restore the previous
+  behavior by setting the configuration value to ``True``.
+
+  To ensure Airflow is secure by default, the raw HTML support in trigger UI has been super-seeded by markdown support via
+  the ``description_md`` attribute. If you have been using ``description_html`` please migrate to ``description_md``.
+  The ``custom_html_form`` is now deprecated. (#35460)
+
