[dependabot]

Bumps pymdown-extensions from 11.0.2 to 12.1.

Release notes

Sourced from pymdown-extensions's releases.

12.1

• NEW: SuperFences: Add optional reset function that can be specified for custom fences.
• FIX: Tilde, Caret: Fix performance for long invalid delimiters.

12.0.1

• FIX: BetterEm: fix a case with new logic.

12.0

• BREAK: BetterEm: Complete rewrite. There may be some subtle differences between legacy behavior and new CommonMark behavior.

  • * and _ emphasis are handled at the same time to provide more natural nesting.
  • More performant.
  • CommonMark compliant.

• BREAK: Tilde, Caret, Mark: Rewritten and now built upon the latest BetterEm logic.

  • When used with BetterEm, Tilde, Caret, and Mark will be added to the same delimiter processor under the hood and will be parsed at the same time as emphasis, allowing for better nesting logic.
  • More performant. Performance issues reported by (@​lexdotdev).
  • Tilde, Caret, Mark: Allow deletion, insertions, and marking mid-word by default. Set smart_delete, smart_insert, or smart_mark, respectively, to enable previous behavior, which prevented mid-word deletion.
  • Tilde, Caret: Add new option no_space to control whether the Pandoc style requirement of "no unescaped spaces" is enabled for subscript and superscript, respectively. no_space is enabled by default.

• NEW: Details, Blocks.Details, Blocks.Admonitions: Allow and handle headers specially in titles.

• NEW: Quotes: Allow and handle headers specially in callout titles.

• NEW: BracketSpan: New extension that allows for the creation of spans using a Pandoc style bracket notation.

• NEW: Arithmatex: Remove deprecated inline_mathjax_preview_format, inline_mathjax_format, and inline_generic_format. Use arithmatex_inline_format instead.

• NEW: Arithmatex: Remove deprecated fence_mathjax_preview_format, fence_mathjax_format, and fence_generic_format. Use arithmatex_fenced_format instead.

• NEW: Emoji: Remove undocumented and deprecated "old style" custom emoji index logic.

• NEW: Slugs: Remove deprecated uslugify, uslugify_encoded, uslugify_cased, uslugify_cased_encoded, gfm, and gfm_encoded. Use the documented slugify method with appropriate arguments instead.
