rails/actionview/CHANGELOG.md

• Alias field_set_tag helper to fieldset_tag to match <fieldset> element

  Sean Doyle

• Deprecate passing content to void elements when using tag.br type tag builders.

  Hartley McGuire

• Fix the number_to_human_size view helper to correctly work with negative numbers.

  Earlopain

• Automatically discard the implicit locals injected by collection rendering for template that can't accept them

  When rendering a collection, two implicit variables are injected, which breaks templates with strict locals.

  Now they are only passed if the template will actually accept them.

  Yasha Krasnou, Jean Boussier

• Fix @rails/ujs calling start() an extra time when using bundlers

  Hartley McGuire, Ryunosuke Sato

• Fix the capture view helper compatibility with HAML and Slim

  When a blank string was captured in HAML or Slim (and possibly other template engines) it would instead return the entire buffer.

  Jean Boussier

• Updated @rails/ujs files to ignore certain data-* attributes when element is contenteditable.

  This fix was already landed in >= 7.0.4.3, < 7.1.0. [CVE-2023-23913]

  Ryunosuke Sato

• Added validation for HTML tag names in the tag and content_tag helper method. The tag and content_tag method now checks that the provided tag name adheres to the HTML specification. If an invalid HTML tag name is provided, the method raises an ArgumentError with an appropriate error message.

  Examples:

  # Raises ArgumentError: Invalid HTML5 tag name: 12p
  content_tag("12p") # Starting with a number
  
  # Raises ArgumentError: Invalid HTML5 tag name: ""
  content_tag("") # Empty tag name
  
  # Raises ArgumentError: Invalid HTML5 tag name: div/
  tag("div/") # Contains a solidus
  
  # Raises ArgumentError: Invalid HTML5 tag name: "image file"
  tag("image file") # Contains a space
