rails--rails/actionview/CHANGELOG.md

## Rails 6.0.0.alpha (Unreleased) ##

*   Enable select tag helper to mark `prompt` option as `selected` and/or `disabled` for `required`
    field. Example:

        select :post, 
               :category, 
               ["lifestyle", "programming", "spiritual"], 
               { selected: "", disabled: "", prompt: "Choose one" }, 
               { required: true }

    Placeholder option would be selected and disabled. The HTML produced:

        <select required="required" name="post[category]" id="post_category">
        <option disabled="disabled" selected="selected" value="">Choose one</option>
        <option value="lifestyle">lifestyle</option>
        <option value="programming">programming</option>
        <option value="spiritual">spiritual</option></select>

*   Don't enforce UTF-8 by default

    With the disabling of TLS 1.0 by most major websites, continuing to run
    IE8 or lower becomes increasingly difficult so default to not enforcing
    UTF-8 encoding as it's not relevant to other browsers.

    *Andrew White*

*   Change translation key of `submit_tag` from `module_name_class_name` to `module_name/class_name`.

    *Rui Onodera*

*   Rails 6 requires Ruby 2.4.1 or newer.

    *Jeremy Daer*
