    *Izumi Wong-Horiuchi*

*   `number_to_percentage` does not crash with `Float::NAN` or `Float::INFINITY`
    as input.

    Fixes #14405.

    *Yves Senn*

*   Add `include_hidden` option to `collection_check_boxes` helper.

    *Vasiliy Ermolovich*

*   Fixed a problem where the default options for the `button_tag` helper is not
    applied correctly.

    Fixes #14254.

    *Sergey Prikhodko*

*   Take variants into account when calculating template digests in ActionView::Digestor.

    The arguments to ActionView::Digestor#digest are now being passed as a hash
    to support variants and allow more flexibility in the future. The support for
    regular (required) arguments is deprecated and will be removed in Rails 5.0 or later.
