TestGolemApp: PKG_TITLE

rmarkdown 2.6

Encoding is correctly handled now in html_vignette when checking for identical title and vignette index entry (thanks, @py-b, #1978).
clean_site() now default to preview = TRUE and will no more remove files without notice. This change will affect the "Clean All" button in the "Build" pane for website project. clean_site(preview = FALSE) must be run to effectively remove files (#1973).
The intermediate .tex file is now correctly deleted if keep_tex = FALSE when the R Markdown document is not rendered from the working directory (thanks, @vqv, #1308).
Fix a bug causing certain resources files to be deleted as intermediate files when intermediates_dir is the same as the input (thanks, @bellma-lilly, #1248).
Fix issues with anchor_sections = TRUE and learnr (thanks, @gadenbuie, #1938).
Enable use of server.R and global.R alongside runtime: shinyrmd documents.
pkg_file_lua() now works with devtools::load_all() and testthat when used in other packages.
Fix pandoc_convert(citeproc = TRUE) not supressing the --natbib or --biblatex options (thanks, @atusy, #1932).
pandoc-citeproc is now activated if a bibliography field is defined in another YAML block instead of the first YAML block (thanks, @bwiernik, #1364).
Specify that htmltools::htmlPreserve() should use the pandoc raw attribute rather than preservation tokens when pandoc >= v2.0. Note that this option will have the intended effect only for versions of htmltools >= 0.5.0.9003.
anchor_sections in html_documents() now defaults to FALSE. It was introduced in previous version with a default to TRUE, but it is reverted now after hearing feedbacks from the community (thank you!). The # is still used as the character for the anchor but you can easily change that using CSS rules. Examples have been added to the help page ?html_document.
Using Pandoc's default for --email-obfuscation now. Previously, it was set to none explicitly, which is the default for Pandoc 1.17.2+ anyway. Only users with a Pandoc version before 1.17.2 may see a change in the content of the html source file produced if the document contains email addresses. This change allows to pass the Pandoc's command line flag if you want to set it to another value (thanks,@seankross, #1969).

yaml output: html_document: pandoc_args: ["--email-obfuscation", "javascript"]

See Pandoc's manual for the meaning of this option.

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 header, 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.

rmarkdown 2.4

Lua filters handling has been improved internally with some user-facing changes (#1899):
- New exported function pandoc_lua_filter_args() to return the Pandoc command-line argument to add a Lua filter.
- New argument lua_filters in pandoc_options() to pass the Lua filter paths to use with a format. This allow output format authors to add filters for a custom format using the pandoc argument of output_format() and to get filters from a format using fmt$pandoc$lua_filters.
- The Lua filters of an output format are now passed to Pandoc in render(). By default, they are passed to Pandoc before any other format-defined or user-defined Pandoc arguments (usually via the pandoc_args option of an output format). This ensures that filters of an output format are executed first. To change the default, you need to deal with it in a custom format (i.e., modify the elements in fmt$pandoc$lua_filters, such as reordering them).
- New exported function pkg_file_lua() to get the full system path of a Lua filter included in a package source within the inst/rmarkdown/lua folder (thanks, @atusy, #1903).
Fixed the path separators for the css parameter in YAML frontmatter for HTML output files under Windows. Previously, forward slashes in css paths were converted to backslashes (thanks, @jonathan-g, #1862).
Since rmarkdown 1.16, Pandoc's fenced Div's are converted to LaTeX environments when the output format is LaTeX, e.g., ::: {.center data-latex=""} is converted to \begin{center}. The attribute data-latex of the Div was mandatory, even if it is empty. In rmarkdown 2.2, we silently drop this requirement, which means ::: {.center} is converted to \begin{center}. This turns out to be a bad idea, because users have no control over which Div's to be converted to LaTeX environments. Previously, they could opt-in by the data-latex attribute, but with rmarkdown 2.3, all Div's are converted to LaTeX environments unconditionally. What's more, this change led to bugs like https://stackoverflow.com/q/62340425/559676 and https://github.com/rstudio/bookdown/issues/883. Therefore the data-latex attribute became mandatory again in this version. If the LaTeX environment does not need arguments, you may use data-latex="".
The two Lua fitlers pagebreak.lua and latex-div.lua (introduced in rmarkdown 1.16) are also applied to the output format beamer_presentation now (thanks, @XiangyunHuang, #1815).
When customizing formats with the output_format function, pre_knit, opts_hooks, and knit_hooks can now refer to rmarkdown::metadata. Previously, rmarkdown::metadata returned list() in these functions (thanks, @atusy, #1855).
rmarkdown::find_external_resources() now discovers external template files. This in turn fixes the rendering issue of html_document with the shiny runtime and intermediate_dir set (thanks, @atusy, @cderv, #1865).
Added the number_sections argument to following formats: github_document, ioslides_presentation, md_document, odt_document, powerpoint_presentation, rtf_document, slidy_presentation, word_document. These are powered by a Lua filter and requires Pandoc > 2.0. It will silently have no effect has before with previous pandoc version (thanks @atusy 1893). Pandoc >= 2.10.1 adds --number-sections for docx format, and thus word_document prefers the native feature to the Lua filter (thanks, @jooyoungseo, #1869).
For the output format pdf_document, the option fig_crop will not be enabled unless both the programs pdfcrop and ghostscript are found (thanks, @dalupus, yihui/knitr#954).
Fixed a bug that a chunk with a class fold-hide hides the rest of the chunks even the output format setting html_document(code_folding = "show") (thanks, @atusy, #1906).
Updated documentation for render() to make it clearer how options are set for the output_format parameter (thanks, @jonathan-g, #1907 and rstudio/bookdown#930).
Ported some CSS styles (e.g., underlines, small caps, and multi-column layouts) from the latest Pandoc's HTML template into rmarkdowns HTML templates (thanks, @atusy, #1878, #1908).

rmarkdown 2.3

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).

rmarkdown 2.2

Exported the internal function find_pandoc(), and also added two arguments, dir and version, so that users can provide a custom directory under which this function may find Pandoc, as well as an expected version of Pandoc to be found (thanks, @connorp, #1785).
pandoc_metadata_arg() is a new Pandoc helper function to generate --metadata argument for Pandoc command line (thanks, @cderv, #1789).
The output format html_vignette() now warns against differences in the vignette title specified in the title field in the YAML metadata and the one specified inside \VignetteIndexEntry{}. Normally they are expected to be identical (#1789).
Fixed a bug with encoding when rendering html_notebook containing HTML widgets (thanks, @cderv, #1799).
TOC title can now be specified for html_document via the top-level option toc-title in the YAML frontmatter (thanks, @atusy, #1771).
Floating TOC can now distinguish upper/lower-cases (thanks, @atusy, #1783).
When code_folding='show' for the output format html_document, code blocks can be individually hidden initially by specifying the chunk option class.source='fold-hide' (thanks, @atusy, #1798).
For LaTeX/PDF output formats pdf_document, beamer_presentation, and context_document, the argument citation_package = 'none' was deprecated, and citation_package = 'default' should be used instead if citations are to be processed by pandoc-citeproc (thanks, @njbart, rstudio/bookdown#754).
output_format() can now inherit keep_md and clean_supporting from base_format when NULL is passed to these arguments. Previously, you must explicitly specify keep_md and/or clean_supporting as TRUE or FALSE in output_format() since they could not inherit the corresponding options of base_format. This behavior was not consisent with other arguments of output_format() (thanks, @atusy, #1823).
The smart argument of most output formats has been removed, because Pandoc's smart extension is enabled by default, and setting smart: false for an output format did not really have any effect (which could be considered a bug, but we want to get rid of this option since it existed only for a historical reason for Pandoc 1.x, and Pandoc 2.x has been released for more than two years). If you want to disable the smart extension, you can use the option md_extensions: -smart of the output format (thanks, @atusy, #1774).
pdf_document() should not specify the geometry variable when the documentclass variable is passed to Pandoc (thanks, @jpcirrus, #1782).
render() now respects the YAML metadata in the R script when rendering the script with Pandoc 2.8 or later (thanks, @nsoranzo #1740, @cderv #1741).
For pandoc_convert(), when the argument to = 'pdf', it will be changed to 'latex' internally (thanks, @JohannesFriedrich, #1802).
render(run_pandoc = FALSE) no longer cleans up the Markdown file (typically knitted from Rmd) (thanks, @BrianDiggs, #1812).

rmarkdown 2.1

Added the returned output from shiny::runApp() within rmarkdown::run() (thanks, @schloerke, #1760).
YAML header is now correctly parsed in html_notebook's intermediate .knit.md file so that features like adding bibliography works again (thanks, @everdark, @cderv, #1747).
ioslides_presentation template no longer generates an empty <h2> tag when subtitle is not specified in YAML (thanks, @jooyoungseo #1735, @cgrudz #1663).
No longer center the #header element in the html_vignette() output (thanks, @EmilHvitfeldt, #1742).
Ensure the tempdir() exists (via tempdir(TRUE)) when writing HTML dependencies to a temporary file, because this directory might be erased by accident (thanks, Kurt Hornik, and also @karawoo #1743).
Added the slide_level argument to slidy_presentation() (https://stackoverflow.com/q/59157211/559676).
Removed the jQuery dependency in html_document_base() (#1723). To avoid bugs like #1723, Pandoc 2.8 users have to upgrade to Pandoc 2.9+.
For pdf_document, horizontal rules generated by Pandoc (before v2.8) stopped working in recent versions of TeX Live, and the same fix as the one to https://github.com/jgm/pandoc/issues/5801 (i.e., hard-code \linethickness to 0.5pt) was applied in rmarkdown (thanks, @cderv, https://stackoverflow.com/a/58646915/559676).

rmarkdown 2.0

For the output format pdf_document(), we no longer adjust the vertical spacing of the title area. This means there will be a larger spacing above the document title in PDF. If you prefers the old (smaller) spacing, please download https://github.com/rstudio/rmarkdown/blob/f6961af/inst/rmd/latex/compact-title.tex and include it to the preamble via the includes option of pdf_document. However, please note that this means you won't be able to have multiple authors in the author field of the YAML frontmatter, unless you use a custom LaTeX template. With the default LaTeX template, you will run into the error in #1716. Besides, the compact-title option in YAML is no longer supported.
R code in the header-includes field in the YAML frontmatter stopped working in the previous version of rmarkdown. The code should be evaluated before passing to Pandoc (thanks, @mcol #1709, @cderv #1710).
The encoding argument is no longer passed to the intermediates_generator of R Markdown output formats. The intermediates_generator function can only accept arguments input_file and intermediates_dir now (see ?rmarkdown::output_format). This is a breaking change to developers. If you are an output format developer, you have to remove the encoding argument in your intermediates_generator if your output format uses this function.
The encoding argument is no longer passed to the render element of the site generator (see ?rmarkdown::render_site).
The encoding argument has been removed from many of the internal functions in the rmarkdown package. Now all input files are assumed to be encoded in UTF-8. If you see an error message like "Error in FUN(arg = ...): unused argument (arg = ...)", please file an issue (with a reproducible example) to https://github.com/rstudio/rmarkdown.
Added a new output format context_document() to support ConTeXT output (thanks, @RLesur #1725, @jooyoungseo #1713).
render_site() can render R scripts in addition to Rmd files if you set autospin: true in _site.yml (thanks, @zeehio, #1564).
Added ext argument to md_document(). Its default value is ".md". This argument is intended to be used together with variant argument (e.g., variant = "context" and ext = ".pdf") (thanks, @atusy, #1715).
ioslides_presentation() stylesheet is updated for printing. Browsers are notified that the presentation should preferentially be printed in landscape orientation and without margin (thanks, @RLesur, #1718).
Reverted the fix #1703 and applied an alternative fix to #1700, because the original fix brought a new bug #1714 (thanks, @pablobernabeu @cderv @everron @aronatkins).
Tabsets don't work with Pandoc 2.8 (thanks, @mnazarov, #1723).
The pdf_document format failed to work if the header-includes field in YAML is an empty list (thanks, @cderv, #1728).

rmarkdown 1.18

For pdf_document(), now we patch Pandoc's built-in LaTeX template to include the document subtitle (unnecessary with pandoc 2.6 onwards) and reduce the vertical spacing before title using --include-in-header rather than overwriting the built-in template, avoiding compability problems with newer versions of Pandoc (thanks, @adunning, #1563).
find_external_resources() works now when multiple files are specified in the includes option of the output format (thanks, @andrie, #1677).
find_external_resources() can find external resources specified in the output format's reference_doc or reference_docx option now (thanks, @jmcphers, #1696).
rmarkdown::run(file = NULL, dir = "foo/") failed to run Rmd files under the foo/ directory (thanks, @jenzopr, #1703).
Reverted the fix for #1692 since it is no longer necessary (https://github.com/yihui/tinytex/issues/152#issuecomment-552796864).
The header-includes field in the YAML metadata will no longer be overwritten by the command-line option --include-in-header (thanks, @crsh @mnazarov, #1359).
Removed the xmlns attribute in the <html> tag in the default HTML template (thanks, @grady #1640, @spgarbet #995).

rmarkdown 1.17

html_vignette() passes self_contained argument value to base format (thanks, @cderv, #1668).
find_external_resources() works for the html_vignette type again, this fixes rendering vignettes with external resources in pkgdown (regression introduced in rmarkdown 1.16, #1668).
render(..., clean = TRUE) may fail to clean the *_files directory when the output format is prettydoc::html_pretty (thanks, @yixuan, #1664).
For ioslides_presentation, images with atributes (e.g., ![](sample.png){width=80%}) can be correctly embedded in the self-contained mode now (thanks, @hadley, #1687).
Fixed the Pandoc LaTeX templates to avoid the error Filegrffile.sty' not found`. This is because the LaTeX grffile is no longer available in TeX Live (thanks, @cderv #1691, @smmurphy #1692, @JacobD05 https://github.com/yihui/tinytex/issues/152).

rmarkdown 1.16

The pandoc-citeproc binary can now be found correctly on Windows. This fixes an issue with pandoc_citeproc_convert() (thanks @cderv, #1651).
Added self_contained argument to html_vignette to keep intermediate directory if self_contained = FALSE (thanks, @cderv, #1641).
It is now possible to add pagebreak in HTML, Word, LaTeX, and ODT documents using the \newpage or \pagebreak command in an Rmd file. This is possible thanks to the Pandoc's pagebreak Lua filter. See vignette("lua-filters", package = "rmarkdown") (thanks, @cderv, #1626).
The Pandoc extension ascii_identifiers is no longer enabled by default. If you still need it, you may use the argument md_extensions = "+ascii_identifiers" in the output format function. However, please note that this will trigger an error in a future version of Pandoc.
Output formats can be configured by arbitrary YAML files, which used to be restricted to _output.yml or _output.yaml. They can be specified via the output_yaml argument of render() or the output_yaml top-level parameter of YAML front matter, and the first existing one will be used. If output_yaml is specified both for render() and YAML front matter, then render() has the priority. If none are found, then _output.yml or _output.yaml will be used if they exist (thanks, @atusy, #1634).
Added a Pandoc Lua filter to convert fenced Divs to LaTeX environments when the output format is latex or beamer. Basically a fenced Div ::: {.NAME data-latex="[OPTIONS]"} is converted to \begin{NAME}[OPTIONS] \end{NAME} in LaTeX. The attribute data-latex must be provided, even if it is an empty string (meaning that the LaTeX environment does not have any optional arguments). For example, ::: {.verbatim data-latex=""} generates a verbatim environment, and ::: {.minipage data-latex="{.5\textwidth}"} generates \begin{minipage}{.5\textwidth}. This Lua filter was originally written by @RLesur at https://github.com/yihui/bookdown-crc/issues/1. It will allow users to create custom blocks that work for both HTML and LaTeX output (e.g., info boxes or warning boxes).
Added keep_html argument to github_document so to save a preview HTML file in a working directory (thanks, @atusy, #1650).

rmarkdown 1.15

Exclude README.R?md from files processed by render_site(),
html_document with code_folding: hide supports showing individual source code chunks if they are assigned the fold-show class via the chunk option class.source="fold-show" (thanks, @atusy, #1602).
The extra_dependencies argument only works with template: default in pdf_document. Now it works with any Pandoc LaTeX templates as long as the template uses the header-includes variable.

rmarkdown 1.14

Fixed a regression in ioslides_presentation that background colors via the data-background attribute on slides stopped working (thanks, @ShKlinkenberg, #1265).
Fixed the bug #1577 introduced in rmarkdown v1.12: tabsets, floating TOC, and code folding in the html_document format no longer work with the shiny runtime (thanks, @RLesur for the fix #1587, and @fawda123 @ColinChisholm @JasonAizkalns for the bug report).
Added the keep_md argument to pdf_document() to keep the intermediate .md output file (thanks, @broomej, #1001).
For render(), if the input filename contains special characters such as spaces or question marks (as defined in rmarkdown:::.shell_chars_regex), the file will be temporarily renamed with the special characters replaced by - (dash) instead of _ (underscore, as in previous versions of rmarkdown). This change will affect users who render such files with caching (cache will be invalidated and regenerated). The change is due to the fact that - is generally a safer character than _, especially for LaTeX output (#1396).
Added a pkgdown site for the rmarkdown package: https://rmarkdown.rstudio.com/docs/ (thanks, @apreshill, #1574).
Fixed the bug #1593: in HTML documents, when a MathJax URL is used with a custom template, the source code of the MathJax library is included in the document. This bug was first declared in bookdown (thanks, @topepo for the bug report rstudio/bookdown#683, and @RLesur for the fix #1594).

rmarkdown 1.13

For pdf_document(), do not override margins to 1 inch when a custom document class or geometry settings are specified in the YAML front matter (thanks, @adunning, #1550)
The default value of the encoding argument in all functions in this package (such as render() and render_site()) has been changed from getOption("encoding") to UTF-8. We have been hoping to support UTF-8 only in rmarkdown, knitr, and other related packages in the future. For more info, you may read https://yihui.org/en/2018/11/biggest-regret-knitr/.
The option toc_float: true for html_document now preserves the text formatting (thanks, @codetrainee, #1548).
For the output_file argument of render(), a file extension will be automatically added if the filename does not contain an extension (e.g., render('foo.Rmd', 'html_document', output_file = 'bar') will generate bar.html); see the help page ?rmarkdown::render for details (thanks, @apreshill, #1551).
TOC items are not correctly indented when toc_float is enabled for the html_document format (thanks, @carolynwclayton #1235 and @RLesur #1243).
Fixed rstudio/shiny#2307 where the second execution of a shiny_prerendred document with href dependencies would cause a prerender check error (thanks, @schloerke, #1562).
The *_files directory is not properly cleared due to the inappropriate fix for #1503 and #1472 in the last version (thanks, @wxli0 #1553, @cderv #1566).
Added an output_extensions argument to pdf_document() to make it possible to enable/disable Pandoc extensions for the LaTeX output format (thanks, @hongyuanjia, rstudio/bookdown#687).

rmarkdown 1.12

Fixed file extensions of output files when using non-markdown Pandoc extensions such as docx+styles (#1494, @noamross).
Added a new argument extra_lines to latex_dependency() to allow users to add extra lines of LaTeX code after \usepackage{}. Also added a helper function latex_dependency_tikz() based on latex_dependency() (#1502, @malcolmbarrett).
Fixed #1529: when the path of an Rmd file contains Unicode characters that cannot be represented in the system native encoding (especially on Windows), rmarkdown::render() may fail.
Applied a correct fix to an old plotly issue ropensci/plotly#463.
HTML widgets used to be hidden when printing ioslides to PDF in Chrome. Now they will be printed correctly.
render(output_format = 'all') may delete the figure directories that are still needed by certain output formats when one output format doesn't need its figure directory (thanks, @rmcd1024 #1472, @cderv #1503).
The <em> tags in the subtitle, date, and author are removed from the default HTML template (thanks, @royfrancis, #1544).

rmarkdown 1.11

Fixed #1483, which prevented the triangle to be displayed in Firefox when <details><summary>...</summary></details> was used (#1485, @bisaloo)
Provided rmarkdown.pandoc.args as a knitr package option in knitr::opts_knit (#1468, @noamross).
Added the exported function pandoc_exec(), which returns the path of the pandoc binary used by the package (#1465, #1466 @noamross).
new_session: true in _site.yml causes render_site() to render each file in a new R session, eliminating some cross-file difficulties, such as function masking (#1326, #1443 @jennybc).
Added the LaTeX command \passthrough in the default LaTeX template for the --listings flag of Pandoc (rstudio/bookdown#591).
The icons in flexdashboard::valueBox() are not of the full sizes due to the upgrade of FontAwesome in #1340 in the previous version (#1388, rstudio/flexdashboard#189).
Added the ability to generate tabset dropdowns, usable by adding the .tabset-dropdown class to a header (e.g., # Heading {.tabset .tabset-dropdown}) (#1405). Thanks @stefanfritsch for contributing the necessary code for this (#1116).
The darkly theme (a darker variant of the Bootswatch flatly theme) has been added to html_document and html_notebook (#1409, #889).
Fixed a regression that caused scrollbars on code blocks when the syntax highlighting theme is not the default (#654, #1399).
Fixed #1407: reactive expressions can break the section headers of Shiny R Markdown documents.
Fixed #1431: render() with the intermediates_dir argument when the output format is powerpoint_presentation with a custom reference_doc fails to find the reference document.
Fixed the website navbar not being able to display submenus properly (#721, #1426).
Added checks for shiny-prerendered documents to find all html dependencies, match all execution packages, and match the major R version (#1420).
Added an argument cache = TRUE to the internal function rmarkdown:::find_pandoc(), so that users can invalidate the cached path of Pandoc via rmarkdown:::find_pandoc(cache = FALSE) (thanks, @hammer, #1482).
Added an RStudio project template for simple R Markdown websites, so that users can create such websites from RStudio: New Project -> New Directory -> Simple R Markdown Website (thanks, @kevinushey, #1470).
Fixed #1471: Pandoc's (version 2.x) syntax highlighting themes don't work well with the Bootstrap style (thanks, @gponce-ars #1471, @cderv #1489).
Fixed the warnings in #1224 and #1288 when calling render() with an absolute output_dir or intermediates_dir.
Fixed #1300: calling render() with intermediates_dir may fail when the intermediate dir is on a difference device or filesystem.
Fixed #1358: calling render() with intermediates_dir will fail if the Rmd document contains bibliography files that are dynamically generated.

rmarkdown 1.10

Added a new argument slide_level to powerpoint_presentation() (#1270).
The tinytex package has become a required dependency (to build R Markdown to PDF).
Added compact-title variable to the LaTeX default templates to control use of LaTeX titling package; defaults to true (#1284).
pdf_document(template = NULL) does not work (#1295).
Restore ability to use any HTML format with R Markdown Websites (#1328).
Add options argument to paged_table() to enable explicit passing of display options.
Add pandoc_citeproc_convert() function for conversion of bibliography files (e.g. BibTeX files).
Update to Font Awesome version 5.0.13 (#1340).
Add site_resources() function for computing resource files required for a website.
Export default_site_generator() function.
The latex_document() format should not clean up the figure directory (thanks, @emiltb, rstudio/bookdown#582).
Enable post processors that change the output file to specify that the base post processor should still be applied to the original output file.

rmarkdown 1.9

Added a new (experimental) output format powerpoint_presentation. If you want to test it, you will need Pandoc >= 2.1 (#1231).

If the tinytex package is installed, PDF output is built through tinytex::latexmk(), otherwise it is generated by rmarkdown:::latexmk(), which has been factored out and improved in the tinytex package, so it is recommended that you install the tinytex package (#1222).

Temporary files created in render() may be cleaned up prematurely, which can cause problems with Shiny R Markdown documents (#1184).
Further improvements regarding compatibility with Pandoc 2.0, e.g. tabbed sections don't work (https://community.rstudio.com/t/3019).

Suppress confusing error messages from knitr::purl() during rmarkdown::find_external_resources() (thanks, @aronatkins #1247, and @paulobrecht #1154).
Fixed the obscure error Error: path for html_dependency not found:, which was due to the HTML dependency of highlight.js (thanks, @bborgesr, #1213).

rmarkdown 1.8

render_site() does not work with _site.yml that does not have the output setting (#1189).
The variables input and output do not work in Shiny R Markdown documents (#1193).
ioslides_presentation fails to embed images (#1197).
With Pandoc 2.x, github_document() generates the wrong filename extension .gfm-ascii_identifiers instead of .md, and line height of code blocks in the HTML preview is too big (#1200).

Add smart option for word_document() format.
Save render intermediates when generating beamer presentations (fixes #1106).
Fixed issues when specifying NULL/null/empty parameter values (#729 and #762).

Upgraded highlight.js from v1.1 to v9.12.0 (#988, #907).
The argument keep_md = TRUE actually preserves the Markdown output file from knitr::knit() now (as documented). Previously, it generates a new Markdown file by concatenating the YAML metadata (title, author, date) with the body of the original Markdown output file (#450).
For md_document(), when variant == 'markdown' and perserve_yaml = TRUE, the Pandoc argument --standalone should not be used (#656).

Support code folding for bash, python, sql, Rcpp, and Stan chunks.
Provide rmarkdown.pandoc.id_prefix as Knit option
Fixed two issue with df_print: paged, one would prevent rendering data with lists of lists and the other where the column type would get cut off.

data.table expressions involving := are no longer automatically printed within R Markdown documents. (#829)
Fix #910: the extra_dependencies argument of pdf_document() does not work when no code chunks contain LaTeX dependencies.
The extra_dependencies of pdf_document() can also take a character vector of LaTeX package names, or a named list of LaTeX package options (with names being package names), which makes it much easier to express LaTeX dependencies via YAML.

Replace backslashes in floating TOC headings (#849)
Suggests rather than Imports for tibble (R 3.0 compatibility)
Add paged_table function for printing paged tables within HTML documents
Support {.active} attribute for setting initially active tab (#789)
Add knit_root_dir argument to render() and YAML header, a convenience for setting knitr's root.dir option

Exclude output_dir from site files (#803)
Export navbar_html and yaml_front_matter functions

Render Shiny documents in a clean environment; fixes issue in which code in Shiny documents could access internal R Markdown state

rmarkdown 0.9.2

Added a fix to #580 for Windows users.

rmarkdown 0.9.1

Fix for a bug causing certain files to be deleted as intermediate files. (#580)
PDF/LaTeX output no longer uses natbib as the citation package by default. If you do want to use natbib or biblatex, you may still use the argument citation_package = 'natbib' or 'biblatex'. (#577)

rmarkdown 0.9

Fix for JS exception in slidy_presentation when served from the filesystem (don't call pushState for file:// urls)
Escape single quotes in file paths
Fix for missing resources when rendering a filename with shell characters
For PDF/LaTeX output, citations are processed via natbib or biblatex instead of pandoc-citeproc. The ciation package natbib or biblatex can be chosen using the argument citation_package in pdf_document(), beamer_presentation(), and tufte_handout(). LaTeX is compiled to PDF via latexmk (https://www.ctan.org/pkg/latexmk/); if it is not installed, a simple emulation will be used (run pdflatex/xelatex/lualatex, bibtex, and makeindex a few times). You are recommended to install latexmk, and please note latexmk requires a Perl installation (this is important especially for Windows users).
Always use the graphics package for PDF output
Fix for the error "cannot change value of locked binding for 'metadata'" when one call of rmarkdown::render() is nested in another one (#248)

Support for opts_template in knitr options
Don't implicitly discover directories when scanning for dependent resources
Fix for slide numbers not showing up in ioslides when served from the filesystem (don't call pushState for file:// urls)
Remove inlining of bootstrap CSS (was workaround for bug now fixed in pandoc)
Allow specifying an R file in calls to find_all_resources

rmarkdown 0.8

Add support for keep_md to word_document
Increase pandoc stack size to 512M (often required for base64 encoding e.g. larger embedded leaflet maps). Stack size can also be controlled by the pandoc.stack.size option.
Allow YAML front matter to be terminated with ...
Automatically generate a user-interface (via a Shiny application) for user specification of values in parameterized reports.
Add tightlist macro for compatibility with pandoc >= 1.14

Automatically discover and include dependent resources (e.g. images, css, etc.) for interactive documents.
Added pandoc_version function.
Use VignetteEncoding directive in html_vignette format
Fix issues related to use of non-ASCII characters in ioslides_presentation
Non-ASCII characters in the YAML data are not marked with the UTF-8 encoding when they are read into R, so character strings in rmarkdown::metadata may be displayed incorrectly (#420)

rmarkdown 0.5.1

Add 'dev' option to output formats to specify output device for figures
Enable use of footnotes in titles of LaTeX documents
Various improvements related to directory detection/handling on Windows
