3.9.1

Development

• Add version v1 of the new built-in theme witiko/diagrams. (#514, #531, #538)

  This version is an alias for an earlier theme named witiko/dot. Future versions of the theme may have backwards-incompatible syntax and behavior, see the discussion in #514 and #531. Therefore, you are encouraged to always specify the version v1 to keep your documents from suddenly breaking. The Markdown package will warn you if you don't.

Fixes

• Make option eagerCache safe to use with plain LuaTeX. (#530, Witiko/lt3luabridge#29)
• In LaTeX, fix bad interaction between heading identifiers and the class name {.unnumbered} (also written as {-}). (#511, 3d2e81d, reported by @jurf)

Documentation

• Add artwork by https://fiverr.com/quickcartoon to directory artwork/. (#533)

  You are welcome to use these artworks in your promotional materials, provided you comply with the license terms specified for each piece. Typically, proper attribution to the artist is required.

Deprecation

• Soft-deprecate the name of the built-in theme witiko/dot in favor of the new theme witiko/diagrams@v1. (#514, #531, #538)

Distribution

• Make markdown-cli executable and symlink it to system directories. (#534, #537, [email protected])
• Install the current package lt3luabridge in Dockerfile. (#530)

Tests

• Reenable eagerCache in tests for plain LuaTeX. (#530, Witiko/lt3luabridge#29)
• Use explcheck to check expl3 code in the continuous integration. (#535, #536, b4e3bfc)
