   * SimpleForm no longer sets the `size` attribute automatically and the `default_input_size` setting
   is now deprecated.
 
-## 2.1.0.dev
-
-### enhancements
-  * `input_field` supports components that don't generate tags
-    as `:min_max`, `:maxlength`, `:placeholder`, `:pattern`, `:readonly`.
-    Closes[#362](https://github.com/plataformatec/simple_form/issues/632).
-    ([@nashby](https://github.com/nashby))
-  * support for Rails eager loading.
-    Closes [#478](https://github.com/plataformatec/simple_form/issues/478).

-    ([@smidwap](https://github.com/smidwap))
-
-### bug fix
-  * Do not lookup for hints if it was explicitly given false.
-  After #405 we added hint classes for the wrappers, but this has forced the
-  loading of the hint text doing I18n lookups, even though it was explicitly
-  given false. This checks for the option in `#has_hint?`, avoiding the lookup
-  in such cases. This issues has been caught with #627, thanks to
-  ([@shwoodard](https://github.com/shwoodard)).
-  * Fix default I18n lookup for association input.
-  ([@nashby](https://github.com/nashby))

-
-### enhancements
-  * Add `button_class` configuration to change the class of buttons. ([@sryche](https://github.com/sryche))

-    This is not backward compatible with the previous versions of SimpleForm.
-    For more informations see [this comment](https://github.com/plataformatec/simple_form/issues/360#issuecomment-3000780).
-    ([@nashby](https://github.com/nashby))
-  * Add a readonly component that does automatically readonly lookup from object
-  * Add support for proc or lambda as option for format validator ([@nashby](https://github.com/nashby))
-  * Handle validates_length_of :is option in maxlength ([@nashby](https://github.com/nashby))

-  * Add :grouped_select input type, mapping to Rails grouped_collection_select helper ([@semaperepelitsa](https://github.com/semaperepelitsa))
-  * Add automatic translation of options for collection inputs given a collection of symbols ([@klobuczek](https://github.com/klobuczek))
-  * Add `:boolean_style` config to change how check boxes and radios will be displayed.
-    Options are `:inline = input + label` (default) and `:nested = label > input`.
-  * Add possibility to give a block to `collection_radio` and `collection_check_boxes`,
-    yielding a custom builder to generate custom label and input structure. It
-    is used internally with the :nested option for `:boolean_style`, and is useful
-    to allow some more customization if required.
-  * Do not generate hidden check box field when using nested boolean style, as it is considered
-    invalid markup in HTML5. This will work by default in Rails > 3.2.1 (not released at this time),
-    and is backported inside SimpleForm builder extensions.

-  * Add `item_wrapper_class` configuration option for collection radio buttons / check boxes inputs.
-  * Change default generator templates to use .form-inputs and .form-actions classes in wrapper divs.
-    (the latter is the default in bootstrap, so this makes it easier to integrate).
-  * Field error now accepts HTML tags ([@edison](https://github.com/edison))
-  * Add `generate_additional_classes_for` config option to selectively disable extra
-    css classes for components - wrapper, label and input. ([krzyzak](https://github.com/krzyzak))
-
-### deprecation
-  * Deprecate part of the old configuration API in favor of the wrapper API which allows you to customize your inputs
-    in a more flexible way. See [this guide](https://github.com/plataformatec/simple_form/wiki/Upgrading-to-Simple-Form-2.0)
-    to know how upgrade.
-  * Deprecate the `translate` configuration in favor of `translate_labels`
-  * Deprecate the `html5` configuration in favor of a new `html5` component
-  * Deprecate `:radio` input type in favor of `:radio_buttons`
-  * Deprecate `collection_radio` form helper in favor of `collection_radio_buttons`

-  * Move default attribute translations out of root - use "defaults" key instead
