Release Notes

facelessuser/pymdown-extensions (pymdown-extensions)

v12.2

12.2

• NEW: Add official support for Python 3.15.
• NEW: Tilde, Caret: For backwards compatibility, disable CommonMark punctuation rules by default. If subscript or
  superscript is disabled in the respective extension, CommonMark rules will be honored again. A new punctuation
  rule has been added to force CommonMark rules. When done, people will need to be aware of punctuation when subscript
  or superscript is enabled and escape any that violates CommonMark rules.
• NEW: Highlight: Highlight now allows in the auto_title_map specifying the title as a simple string or a
  dictionary containing the title and the title mode: either text or html, with text being the default. This
  allows a title to be specified and treated as HTML when the mode is html.
• NEW: SuperFences: Add new title_mode option for Pygments fenced blocks that allows a user to specify a title
  to be treated as HTML via title_mode="html".
