[dependabot]

Bumps pymdown-extensions from 10.18 to 10.21.3.

Release notes

Sourced from pymdown-extensions's releases.

10.21.3

• FIX: Fix regression that allows a snippet to be loaded outside of the base path using directory traversal when restrict_base_path is enabled (the default). Found by @​gistrec.

10.21. 2

10.21.2

• FIX: Highlight: Latest Pygments versions cannot handle a "filename" for code block titles of None.

10.20.1

• FIX: Quotes: Ensure the first class for callouts (the alert type) is always rendered lowercase.

10.21

• NEW: Caption: Add support for specifying not only IDs but classes and arbitrary attributes. Initial work by @​joapuiib.
• FIX: MagicLink: Fix a matching pattern for Bitbucket repo.

10.20

• NEW: Quotes: New blockquotes extension added that uses a more modern approach when compared to Python Markdown's default. Quotes specifically will not group consecutive blockquotes together in the same lazy fashion that the default Python Markdown does which follows a more modern trend to how parsers these days handle block quotes.

  In addition, Quotes also provides an optional feature to enable specifying callouts/alerts in the style used by GitHub and Obsidian.

10.19.1

• FIX: Arithmatex: Fix issue where block $$ math used inline within a paragraph could result in nested math parsing.

10.19

• NEW: Emoji: Update Twemoji to use Unicode 16.
• NEW: Critic: Roll back view mode deprecation as some still like to use it, though further enhancements to this mode are not planned.
