v9.10

Compare Source

9.10

• NEW: Blocks: Add new experimental general purpose blocks that provide a framework for creating fenced block
  containers for specialized parsing. A number of extensions utilizing general purpose blocks are included and are meant
  to be an alternative to (and maybe one day replace): Admonitions, Details, Definition Lists, and Tabbed. Also adds a
  new HTML plugin for quick wrapping of content with arbitrary HTML elements.
• NEW: Highlight: When enabling line spans and/or line anchors, if a code block has an ID associated with it, line
  ids will be generated using that code ID instead of the code block count.
• NEW: Snippets: Expand section syntax to allow section names with - and _.
• NEW: Snippets: When check_paths is enabled, and a specified section is not found, raise an error.
• NEW: Snippets: Add new experimental feature dedent_sections that will de-indent (remove any common leading
  whitespace from every line in text) from that block of text.
• NEW: MagicLink: Update GitLab links to match recent changes and to be more correct.
• NEW: MagicLink: Relax required hash length when performing link shortening.
