Development:

• In theme witiko/diagrams, add parameter format for PlantUML diagrams. (reported by @mrkissinger in #555, fixed by @Witiko in 7d58f3d and 64c78f1)

  Here is an example LaTeX document using the new parameter:

  \documentclass{article}
  \usepackage[import=witiko/diagrams@v2, relativeReferences]{markdown}
  \begin{document}
  \begin{markdown}
  ``` plantuml {caption="An example UML sequence diagram" format=eps width=7cm #plantuml}
  @startmindmap
  + SIR
  ++ 指標引擎
  @endmindmap
  ```
  
  See the diagram in Figure <#plantuml>.
  \end{markdown}
  \end{document}

Documentation:

• Add preprint and artwork for an upcoming TUGboat article titled "Piping YAML files into LaTeX3 key–values". (c684ce2, 2214706, 52ccb7a, 85e9680)

Docker:

• Start building Docker images witiko/markdown:TL2024-historic. (bcae00a)
• Switch Docker images witiko/markdown:latest from TeX Live 2024 to 2025. (bcae00a)
