rmarkdown 2.5

• Tables without header rows (wich can be possible in Pandoc's simple table) are now formatted correctly when using html_document() format (thanks, @fkohrt, #1893).

• html_document gains the anchor_sections argument, which is TRUE by default, so that readers can get links to section headers easily---when you mouse over a section hader, you will see a hash symbol # at the end of the header, which contains the anchor link to this header. You can click on this link and get the URL in the addres bar of your web browser, or right-click on it and copy the URL from the context menu. The hash symbol is defined by the CSS rule a.anchor-section::before {content: '#';}. You can customize it by overriding this rule (e.g., via the css argument of html_document) and use any other symbols or icons, e.g., content: "\02AD8;" (thanks, @atusy, #1884).

• pkg_file_lua() should have thrown an error if the expected Lua file does not exist.

• Provide files_dir and intermediates_dir as attributes on return from render() when run_pandoc = FALSE.

• Supports new Pandoc 2.11 --citeproc flags usage instead of pandoc-citeproc external filter. pandoc_convert() and pandoc_citeproc_convert() will now use the correct flags according to the Pandoc version used. The logic is exported in pandoc_citeproc_args(). See Pandoc release note for more information about the new citeproc processing (#1916).

• Fixed the code highlighting when code block is hidden. Previous version introduced a regression where non default code highlighting was still shown when code_folding is activated and code block is hidden (thanks, @matthewcarlucci, #1921).

• The minimal required version for the xfun package (v0.15) has been specified for R Markdown Notebooks to work properly (thanks, @jmcphers, #1923).

• Fixed a bug in convert_ipynb() when the language is not specified in the .ipynb file (thanks, @acca3003, #1925).

• Introduce runtime: shinyrmd as a more user friendly alias for runtime: shiny_prerendered.
