rails--rails/actionview/CHANGELOG.md

*   Change the default template handler from `ERB` to `Raw`.

    Files without a template handler in their extension will be rendered using the raw
    handler instead of ERB.

    *Rafael Mendonça França*

*   Remove deprecated `AbstractController::Base::parent_prefixes`.

    *Rafael Mendonça França*

*   Default translations that have a lower precedence than a html safe default,
    but are not themselves safe, should not be marked as html_safe.

    *Justin Coyne*

*   Make possible to use blocks with short version of `render "partial"` helper.

    *Nikolay Shebanov*

*   Add a `hidden_field` on the `file_field` to avoid raise a error when the only
    input on the form is the `file_field`.

    *Mauro George*

*   Add an explicit error message, in `ActionView::PartialRenderer` for partial
    `rendering`, when the value of option `as` has invalid characters.

    *Angelo Capilleri*
