rails/actionview/CHANGELOG.md

• number_to_percentage does not crash with Float::NAN or Float::INFINITY as input when precision: 0 is used.

  Fixes #19227.

  Yves Senn

• Fixed the translation helper method to accept different default values types besides String.

  Ulisses Almeida

• Collection rendering automatically caches and fetches multiple partials.

  Collections rendered as:

  <%= render @notifications %>
  <%= render partial: 'notifications/notification', collection: @notifications, as: :notification %>
  

  will now read several partials from cache at once, if the template starts with a cache call:

  # notifications/_notification.html.erb
  <% cache  notification do %>
    <%# ... %>
  <% end  %>
  

  Kasper Timm Hansen

• Fixed a dependency tracker bug that caused template dependencies not count layouts as dependencies for partials.

  Juho Leinonen

• Extracted ActionView::Helpers::RecordTagHelper to external gem (record_tag_helper) and added removal notices.

  Todd Bealmear

• Allow to pass a string value to size option in image_tag and video_tag.

  This makes the behavior more consistent with width or height options.

  Mehdi Lahmam

• Partial template name does no more have to be a valid Ruby identifier.

  There used to be a naming rule that the partial name should start with underscore, and should be followed by any combination of letters, numbers and underscores. But now we can give our partials any name starting with underscore, such as _🍔.html.erb.

  Akira Matsuda

• 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

• Allow entries without a link tag in AtomFeedHelper.
