  • Added support for footnotes, fenced Divs, section numbers, {} attributes for images/headings/fenced Divs, and appendices. See vignette('intro', package = 'markdown') for details.

  • A lot of enhancements to the HTML slides format. See vignette('slides', package = 'markdown') for details.

  • Added vignette('article', package = 'markdown') to demonstrate how to write an HTML article.

  • If the input to mark() is a file, the output will also be a file by default. Previously the output would be text. If you want mark() to return text output when the input is a file, you may specify the argument output = NULL.

  • The Markdown option base64_images has been renamed to embed_resources. This option can take two possible values, "local" and "https", meaning whether to embed local and/or web (https) resources. You can specify none, either, or both of them. See vignette('intro', package = 'markdown') for details.

  • Removed the option standalone from the list of Markdown options. Please use the argument template = TRUE/FALSE of mark() instead. The option standalone = TRUE was equivalent to template = TRUE.

  • Added the option auto_identifiers (enabled by default) to automatically add IDs to headings, e.g., # Hello world! will be converted to <h1 id="hello-world">Hello world!</h1>. You can certainly override the automatic ID by providing an ID manually via the {#id} attribute, e.g., # Hello world! {#hello}.

  • Renamed the mathjax option to js_math to allow for other JS math libraries. The default library was changed from MathJax to KaTeX. To continue using MathJax, you may set js_math: mathjax.

  • Removed the option mathjax_embed from the list of Markdown options. To embed the MathJax library, enable "https" in the embed_resources option instead. Note that only MathJax v3 can be partially embedded, and lower versions cannot.

  • Renamed the option highlight_code to js_highlight, and added support for an alternative syntax highlighting JS library Prism.js, which became the default. To continue using the old default highlight.js, you may set the js_highlight option to highlight.

  • The default version of MathJax has been changed from v2 to v3.

  • The default version of highlight.js has been changed from 11.6.0 to 11.7.0, and the default style has been switched from github to xcode.
