-*   Allow the use of callable objects as group methods for grouped selects.
 
-    Until now, the `option_groups_from_collection_for_select` method was only able to
-    handle method names as `group_method` and `group_label_method` parameters,
-    it is now able to receive procs and other callable objects too.
 
-    *Jérémie Bonal*
-
-*   Add `preload_link_tag` helper
-
-    This helper that allows to the browser to initiate early fetch of resources
-    (different to the specified in `javascript_include_tag` and `stylesheet_link_tag`).
-    Additionally, this sends Early Hints if supported by browser.

-
-*   Change `form_with` to generates ids by default.
-
-    When `form_with` was introduced we disabled the automatic generation of ids
-    that was enabled in `form_for`. This usually is not an good idea since labels don't work
-    when the input doesn't have an id and it made harder to test with Capybara.
-
-    You can still disable the automatic generation of ids setting `config.action_view.form_with_generates_ids`
-    to `false.`
-
-    *Nick Pezza*
-
-*   Fix issues with `field_error_proc` wrapping `optgroup` and select divider `option`.
-
-    Fixes #31088
-
-    *Matthias Neumayr*
-
-*   Remove deprecated Erubis ERB handler.
-
-    *Rafael Mendonça França*
-
-*   Remove default `alt` text generation.
-
-    Fixes #30096
-
-    *Cameron Cundiff*
-
-*   Add `srcset` option to `image_tag` helper.
-
-    *Roberto Miranda*
-
-*   Fix issues with scopes and engine on `current_page?` method.
-
-    Fixes #29401.
-
-    *Nikita Savrov*
-
-*   Generate field ids in `collection_check_boxes` and `collection_radio_buttons`.
-
-    This makes sure that the labels are linked up with the fields.
-
-    Fixes #29014.
-
-    *Yuji Yaginuma*
-
-*   Add `:json` type to `auto_discovery_link_tag` to support [JSON Feeds](https://jsonfeed.org/version/1)
-
-    *Mike Gunderloy*
-
-*   Update `distance_of_time_in_words` helper to display better error messages
-    for bad input.
