+*   Add extension synonyms `yml` and `yaml` for MIME type `application/x-yaml`.
+
+   *bogdanvlviv*
+
+*   Adds support for including ActionController::Cookies in API controllers.
+    Previously, including the module would raise when trying to define
+    a `cookies` helper method. Skip calling #helper_method if it is not
+    defined -- if we don't have helpers, we needn't define one.
+
+    Fixes #24304
+
+    *Ryan T. Hosford*
+
+*   ETags: Introduce `Response#strong_etag=` and `#weak_etag=` and analogous
+    options for `fresh_when` and `stale?`. `Response#etag=` sets a weak ETag.
+
+    Strong ETags are desirable when you're serving byte-for-byte identical
+    responses that support Range requests, like PDFs or videos (typically
+    done by reproxying the response from a backend storage service).
+    Also desirable when fronted by some CDNs that support strong ETags
+    only, like Akamai.
+
+    *Jeremy Daer*
+
+*   ETags: No longer strips quotes (") from ETag values before comparing them.
+    Quotes are significant, part of the ETag. A quoted ETag and an unquoted
+    one are not the same entity.
+
+    *Jeremy Daer*
+
+*   ETags: Support `If-None-Match: *`. Rarely useful for GET requests; meant
+    to provide some optimistic concurrency control for PUT requests.
+
+    *Jeremy Daer*
+
+*   `ActionDispatch::ParamsParser` is deprecated and was removed from the middleware
+    stack. To configure the parameter parsers use `ActionDispatch::Request.parameter_parsers=`.
+
+    *tenderlove*
+
+*   When a `respond_to` collector with a block doesn't have a response, then
+    a `:no_content` response should be rendered.  This brings the default
+    rendering behavior introduced by https://github.com/rails/rails/issues/19036
+    to controller methods employing `respond_to`.
+
+    *Justin Coyne*
+
+*   Add `ActionController::Parameters#dig` on Ruby 2.3 and greater, which
+    behaves the same as `Hash#dig`.
+
+    *Sean Griffin*
+
+*   Add request headers in the payload of the `start_processing.action_controller`
+    and `process_action.action_controller` notifications.
+
+    *Gareth du Plooy*
+
+*   Add `action_dispatch_integration_test` load hook. The hook can be used to
+    extend `ActionDispatch::IntegrationTest` once it has been loaded.
+
+    *Yuichiro Kaneko*
+
+*   Update default rendering policies when the controller action did
+    not explicitly indicate a response.
+
+    For API controllers, the implicit render always renders "204 No Content"
+    and does not account for any templates.
+
+    For other controllers, the following conditions are checked:
+
+    First, if a template exists for the controller action, it is rendered.
+    This template lookup takes into account the action name, locales, format,
+    variant, template handlers, etc. (see `render` for details).
+
+    Second, if other templates exist for the controller action but is not in
+    the right format (or variant, etc.), an `ActionController::UnknownFormat`
+    is raised. The list of available templates is assumed to be a complete
+    enumeration of all the possible formats (or variants, etc.); that is,
+    having only HTML and JSON templates indicate that the controller action is
+    not meant to handle XML requests.
+
+    Third, if the current request is an "interactive" browser request (the user
+    navigated here by entering the URL in the address bar, submitting a form,
+    clicking on a link, etc. as opposed to an XHR or non-browser API request),
+    `ActionView::UnknownFormat` is raised to display a helpful error
+    message.
+
+    Finally, it falls back to the same "204 No Content" behavior as API controllers.
