html_document (and html_document_base)'s theme parameter now understands bslib::bs_theme() objects/arguments, meaning that one may opt-into Bootstrap 4 and more easily create custom themes. For examples, see #1706, and for context, see https://rstudio.github.io/bslib/ (thanks, @cpsievert, #1706).

Files with .scss/.sass extension (i.e., Sass files) provided to html_document's css parameter are now compiled to CSS using the {sass} package. Also, if theme is a {bslib} object, these Sass files may utilize Sass code inside the theme (thanks, @cpsievert, #1706).

Fix an issue with line numbering in code chunks when .numberlines with Pandoc's highlighting (thanks, @aosavi, #1876).

Fix an issue with shiny runtime and global.R (thanks, @liaojiahui-r, rstudio/flexdashboard#298).

Accept latex="{options}", latex=1, or latex=true for Latex Divs.

Add output_format_filter function to default_site_generator(). Enables custom site generators to customize or even entirely replace the output format right before rendering of each page.

Automatically exclude renv directory for render_site() (thanks, @jmbuhr, #1996)

Do not force options(htmltools.preserve.raw = TRUE) when this option has been set, otherwise it is impossible for other packages to turn this option off, e.g., yihui/xaringan#293.

knitr_options_pdf() will now throw a warning when fig_crop = TRUE but is disabled because required tools pdfcrop and/or ghostscript are missing (thanks, @netique, #2016).

Eliminated the unnecessary padding in code blocks in the html_document output with Bootstrap 4 themes (thanks, @atusy, #2019).

github_document() will produce a working TOC even if some headers start with number (#2039).

Fix an issue with knit_print.data.frame. The ... arguments are no more passed to print() to avoid passing knit_print() arguments options and encoding to custom print() methods (#2047).
