rmarkdown 2.3

on GitHub

Addressed an accessibility issue in highlighted code blocks of HTML output for screen reader users: screen readers no longer read out an unnecessary code line id values (thanks, @jooyoungseo and @atusy, #1833).

Added file_scope option to output format definition. This enables handling of duplicate numeric footnote identifiers (e.g. across bookdown chapters) via the pandoc --file-scope option (#1837).

Added the customizable lang attribute to ioslides_presentation output (thanks, @jooyoungseo, #1841).

Added publish_site() function for "one-button" publishing of R Markdown websites.

When the df_print option is kable and the output format is not HTML, <div class="kable-table"> is no longer added to the kable() output, because recent versions of Pandoc will convert the div to a LaTeX environment when the output format is LaTeX (thanks, Laurens, https://stackoverflow.com/q/62340425/559676).

html_vignette() only warns against differences in the vignette title and the vignette index entry for R >= 3.6.0 (thanks, @krlmlr, #1832).

html_document() can apply code_folding on any chunk engines if the foldable class is added to a source code block via the chunk options (class.source or attr.source). You may apply this feature to all the source code blocks, for example, by setting knitr::opts_chunk$set(class.source = "foldable") at the beginning of your document (thanks, @atusy, #1835).
