Vít Starý Novotný submitted an update to the markdown package. Version: 3.15.1-0-g51841b67 2026-06-11 License: lppl1.3c Summary description: Converting and rendering markdown documents inside TeX Announcement text:

### Fixes This version of the Markdown package has fixed the following issues: - Define unexpandable functions as protected. ([witiko/expltools#201][expltools-201], #644) [expltools-201]: https://github.com/witiko/expltools/pull/201 ### Defaults This version of the Markdown package has made the following changes to the default renderer and renderer prototype definitions. - Render bracketed spans by default. (8c3b0716) Previously, bracketed span contents were consumed by the default renderer prototype. - In LaTeX, format `[...]{.acronym}`s throughout the document. (#645) After this change, explicitly listed acronyms using the HTML class `acronym` will be recorded in the auxiliary file, so that they are applied throughout the document in the next compilation run. For example, assume the following LaTeX example document: ``` tex \documentclass{article} \usepackage[bracketed_spans]{markdown} \markdownSetup { acronyms = {HTML, YAML}, } \begin{document} \begin{markdown} HTML, JSON, and YAML are two staples of modern tooling that often get mentioned in the same breath, even though they live in very different layers of the stack. Here, the author has explicitly marked up [JSON]{.acronym}. \end{markdown} \begin{markdown} In the following compilation runs, the previous occurrence of JSON will also be correctly formatted as an acronym. \end{markdown} \end{document} ``` During the first compilation run, only HTML and YAML are formatted as acronyms in the first paragraph, not JSON, which is only formatted as an acronym in the second and third paragraphs. However, in the following compilation runs, JSON is formatted as an acronym throughout. ### Continuous integration This version of the Markdown package has made the following changes to our continuous integration: - Bump `softprops/action-gh-release` from 2 to 3. (added by @dependabot in #643)
