• Render MissingAttachable as "☒" in plain text.

  Previously, Content#to_plain_text would replace a MissingAttachable with a blank string. Now it renders the same "☒" character used in the HTML representation.

• Add to_markdown to Action Text, mirroring to_plain_text.

  Converts rich text content to Markdown, supporting headings, bold, italic, strikethrough, inline code, code blocks, blockquotes, ordered and unordered lists, links, tables, and attachments. Custom attachment representations can be provided by implementing attachable_markdown_representation on the attachable model.

  message = Message.create!(content: "<h1>Hello</h1><p>This is <strong>bold</strong></p>")
  message.content.to_markdown # => "# Hello\n\nThis is **bold**"

• Deprecate Trix-specific classes, modules, and methods

  • ActionText::Attachable#to_trix_content_attachment_partial_path. Override #to_editor_content_attachment_partial_path instead.
  • ::ActionText::Attachments::TrixConversion
  • ActionText::Content#to_trix_html.
  • ActionText::RichText#to_trix_html.
  • ::ActionText::TrixAttachment

• Validate RemoteImage URLs at creation time.

  RemoteImage.from_node now validates the URL before creating a RemoteImage object, using the same regex that AssetUrlHelper uses during rendering. URLs like "image.png" that would previously have been passed to the asset pipeline and raised a ::ActionView::Template::Error are rejected early, and gracefully fail by resulting in a MissingAttachable.
