v1.3.0

lot of tweaks and improvements that have been building up, mostly driven with Claude.
Hopefully the code should be quite a lot more robust now.

Main new feature is the ability to run with .mdx files as well as .md, using {/* */} comments.

Breaking changes

• 💥 Minimum supported Python is now 3.10, up from 3.7 (#61)

New features

• ✨ MDX support: .mdx files are searched by default, and config can be written as JSX comments ({/* RICH-CODEX ... */}), as MDX doesn't allow HTML comments (#58)
• ✨ New --no-dedupe option, to run duplicate commands (#33)
• ✨ extra_env can now be set once for all commands (#57)
• ✨ Smaller SVG diffs thanks to a stable ID based on the output path (#60)
• ✨ CLI table now shows source line numbers and output filenames (#57)
• ✨ Tidier --help, with the options grouped into panels (#57)
• ✨ New skip_install action input, mostly for self-testing rich-codex changes (#61)

Updates

• ♻️ Removed /CreationDate filter for PDFs as it never worked. Use min_pct_diff for PDF outputs instead (#60)
• ♻️ New unit test suite (#60), type annotations checked with mypy (#62), prek and ruff in place of pre-commit, black, flake8 and isort, and CI across Python 3.10 - 3.14 (#61)

Bugs fixed

• 🐛 skip_change_regex never matched anything, so images updated regardless (#60)
• 🐛 outputs is now optional in config files (#57)
• 🐛 Writing an SVG alongside a PNG or PDF in one go could delete the SVG (#60)
• 🐛 The Docker image can now write PNG and PDF files (#61)
• 🐛 Action: use_uv: true could never install rich-codex (#61)
• 🐛 Action: commit_changes: "false" committed and pushed anyway. Same for error_changes (#61)
• 🐛 Action: using rich-codex twice in one workflow run failed, as both uploaded their log with the same artifact name (#61)
• 🐛 Action: the python_verison input was a typo and was being ignored anyway. Use python_version; the old name still works but warns (#57)
