Sourced from pymdown-extensions's releases.

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.

9.10b5

• NEW: Blocks: Add type_multi and type_none validators.
• NEW: Blocks: Rename on_parse to on_validate and pass in parent element as context for validation.
• NEW: Blocks: When a block uses raw mode, allow content to be indented to avoid conflicts with HTML parser. raw blocks should be indented and are now documented as such. The results will be dedented up to Python Markdown's tab length, so intentional indentation is still possible. raw blocks with no indentation will still work, but may have conflicts with other extensions.
• FIX: Blocks: Commenting out all YAML options will not cause a block to invalidate.

9.10b4

• NEW: Blocks: Add on_inline_end event.

9.10b3

• NEW: Blocks: Ensure inline mode is handled properly.
• NEW: Blocks: When using raw mode, ensure HTML stashed content is extracted.
• NEW: HTML: The Blocks HTML extension should use inline specifier instead of span.
