  lists of lists and the other where the column type would get cut off.

* Better support for `citation_package: biblatex` in `pdf_document()` (#1062).

* On certain Windows platforms, compiling LaTeX to PDF may fail because
  `system2(stdout = FALSE)` is not supported, in which case the default `system2()`

* 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.

* Automatically ignore packrat directory for render_site

* Fix #943: escape end tags in shiny_prerendered code contexts

* Prepend "section-" to ids in runtime: shiny[_prerendered] to eliminate
  potential conflicts with shiny output ids

* Use html_dependencies for highlight.js, pagedtables, slidy, ioslides,
  & navigation (improved dependency behavior for runtime: shiny[_prerendered])

  into R as the name of a list (#841)

* Remove key-column special-case left alignment in pagedtables (#829)

* 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

* Parameter editing: don't allow NULL to overwrite previous state

* Parameter editing: fix incorrect name for parameters with expressions

* Parameter editing: allow multiple values when the parameter is configured
  to use a "multiple" selector

* Switched the order in which format dependencies are added for
  `html_document` so that `extra_dependencies` are added at the end, after
  bootstrap, etc. (#737)

* `pdf_document(keep_tex = TRUE)` will generate the .tex document even if PDF
  conversion fails (#779).

* Move latex header includes to just before \begin{document}

* Special 'global' chunk label for runtime: shiny which designates
  a chunk to be run once and only once in the global environment
  (startup performance improvement for multi-user shiny documents)

* Ensure supporting files are writeable (#800)

* Make the "show code" buttons more CSS-friendly (#795)

* The filename extension .bib will be removed before bibliography files are
  passed to Pandoc when the output is LaTeX/PDF and the citation package natbib
  or biblatex is used on Windows. This is because bibtex in MikTeX will always
  add the extension .bib to bibliography files, e.g. it treats foo.bib as
  foo.bib.bib. (#623)

* 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

  when rendering an `html_document` with `self_contained: false` and a path is
  passed in argument `output_dir`. (#551)

* Add always_allow_html option for preventing errors when html_dependencies are
  rendered in non-HTML formats (e.g. pdf_document or word_document).

* Fix for an issue causing resources not to be discovered in some documents
  containing an empty quoted string (`""`) in an R chunk.

* Allow specifying an R file in calls to find_all_resources

rmarkdown 0.8
--------------------------------------------------------------------------------

* Add support for keep_md to word_document

  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

* Bugfix: Handle slashes correctly on Windows for slidy_presentation
  when self_contained = FALSE


rmarkdown 0.7
--------------------------------------------------------------------------------

  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)

* Various improvements to tufte_handout format


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


rmarkdown 0.4.2
--------------------------------------------------------------------------------
