Release CHANGES IN bookdown VERSION 0.4 · rstudio/bookdown

NEW FEATURES

Added special syntax for unnumbered part headers: # (PART\*). Numbered parts should be written after # (PART) as before (thanks, @brooksambrose, http://stackoverflow.com/q/43688902/559676).
The gitbook output format also supports abstract in YAML now (thanks, @maxheld83, #311).
For the gitbook output format, the downloads option in config supports rmd now (e.g. download: ["pdf", "epub", "rmd"]) if the edit link has been specified and is a link to Github (thanks, @coatless, #330).
You can set the global R option bookdown.post.latex via options() to be a function to post-process the LaTeX output of the pdf_book format; see ?bookdown::pdf_book for details (thanks, @nicksolomon, #373).

The HTML output file is not moved to the output directory when split_by = 'none' in bookdown::gitbook or bookdown::html_book (http://stackoverflow.com/q/40976073/559676).
The YAML option includes: before_body works correctly for gitbook output now (thanks, @benmarwick, #267).
Theorem environments are not defined for LaTeX output unless a theorem block is present (thanks, @JeffreyRacine, #291).
For remark and proof blocks, the chunk option name did not work correctly for non-LaTeX output (thanks, @ugroempi, #347).
Some text references do not work for HTML and Word output (thanks, @ugroempi, #363).
The option chapter_name in _bookdown.yml does not work when it is specified as a function (thanks, @tzerk, 0c05c38).
External assets such as fonts/css files should never be wiped when rendering a book to HTML (thanks, @nicholaelaw, #398).

The daemon argument was removed from serve_book(), but you can still pass it to servr::httw() via the ... argument.
Added a small space (padding) to the right of section numbers in gitbook output, so that the section numbers are better separated from the titles (thanks, @aronatkins, #367).
