3.0.0 - 2023-06-03

⚠️ This release contains some minor breaking changes in the internal API and improvements to the parsing strictness.

Full Changelog: executablebooks/markdown-it-py@v2.2.0...v3.0.0

⬆️ UPGRADE: Drop support for Python 3.7

Also add testing for Python 3.11

⬆️ UPGRADE: Update from upstream markdown-it 12.2.0 to 13.0.0

A key change is the addition of a new Token type, text_special, which is used to represent HTML entities and backslash escaped characters. This ensures that (core) typographic transformation rules are not incorrectly applied to these texts. The final core rule is now the new text_join rule, which joins adjacent text/text_special tokens, and so no text_special tokens should be present in the final token stream. Any custom typographic rules should be inserted before text_join.

A new linkify rule has also been added to the inline chain, which will linkify full URLs (e.g. https://example.com), and fixes collision of emphasis and linkifier (so http://example.org/foo._bar_-_baz is now a single link, not emphasized). Emails and fuzzy links are not affected by this.
