+deprecated_features:
+  - playbook - The ``timedout.frame`` task result value (injected when a task timeout occurs) is deprecated.
+    Include ``error`` in the ``DISPLAY_TRACEBACK`` config value to capture a full Python traceback for timed out actions.
+
+  - Jinja test plugins - Returning a non-boolean result from a Jinja test plugin is deprecated.
+
+  - YAML parsing - Usage of the YAML 1.1 ``!!omap`` and ``!!pairs`` tags is deprecated.
+    Use standard mappings instead.
+
+  - YAML parsing - Usage of the undocumented ``!vault-encrypted`` YAML tag is deprecated.
+    Use ``!vault`` instead.
+
+  - public API - The ``ansible.errors.AnsibleFilterTypeError`` exception type has been deprecated.
+    Use ``AnsibleTypeError`` instead.
+
+  - public API - The ``ansible.errors._AnsibleActionDone`` exception type has been deprecated.
+    Action plugins should return a task result dictionary in success cases instead of raising.
+
+  - public API - The ``ansible.module_utils.common.json.json_dump`` function is deprecated.
+    Call Python stdlib ``json.dumps`` instead, with ``cls`` set to an Ansible profile encoder type from ``ansible.module_utils.common.json.get_encoder``.
+
+  - config - The ``DEFAULT_UNDEFINED_VAR_BEHAVIOR`` configuration option is deprecated and no longer has any effect.
+    Attempting to use an undefined variable where undefined values are unexpected is now always an error.
+    This behavior was enabled by default in previous versions, and disabling it yielded inconsistent results.
+
+  - config - The ``STRING_TYPE_FILTERS`` configuration option is deprecated and no longer has any effect.
+    Since the template engine now always preserves native types, there is no longer a risk of unintended conversion from strings to native types.
+
+  - config - The ``DEFAULT_ALLOW_UNSAFE_LOOKUPS`` configuration option is deprecated and no longer has any effect.
+    Ansible templating no longer encounters situations where use of lookup plugins is considered "unsafe".
+
+  - config - Using the ``DEFAULT_MANAGED_STR`` configuration option to customize the value of the ``ansible_managed`` variable is deprecated.
+    The ``ansible_managed`` variable can now be set the same as any other variable.
+
+  - config - Using the ``DEFAULT_JINJA2_EXTENSIONS`` configuration option to enable Jinja2 extensions is deprecated.
+    Previously, custom Jinja extensions were disabled by default, as they can destabilize the Ansible templating environment.
+    Templates should only make use of filter, test and lookup plugins.
