@yihui yihui released this on 23 Nov 2016 · 49 commits to master since this release
NEW FEATURES
added a new hook function hook_pngquant() that can call pngquant to optimize PNG images (thanks, @slowkow, #1320)
BUG FIXES
not really a knitr bug, but knit_params() should be better at dealing with multibyte characters now due to the bug fix in the yaml package viking/r-yaml#6

CHANGES IN knitr VERSION 1.15
@yihui yihui released this on 10 Nov 2016 · 63 commits to master since this release
NEW FEATURES
NA values can be displayed using different characters (including empty strings) in kable(); you can set the option knitr.kable.NA, e.g. options(knitr.kable.NA = '') to hide NA values (#1283)
added a fortran95 engine (thanks, @stefanedwards, #1282)
added a block2 engine for R Markdown documents as an alternative to the block engine; it should be faster and supports arbitrary Pandoc's Markdown syntax, but it is essentially a hack; note when the output format is LaTeX/PDF, you have to define \let\BeginKnitrBlock\begin \let\EndKnitrBlock\end in the LaTeX preamble
figure captions specified in the chunk option fig.cap are also applied to HTML widgets (thanks, @byzheng, rstudio/bookdown#118)
when the chunk option fig.show = 'animate' and ffmpeg.format = 'gif', a GIF animation of the plots in the chunk will be generated for HTML output (https://twitter.com/thomasp85/status/785800003436421120)
added a width argument to write_bib() so long lines in bib entries can be wrapped
the inline syntax r#code is also supported besides r code; this can make sure the inline expression is not split when the line is wrapped (thanks, Dave Jarvis)
provided a global R option knitr.use.cwd so users can choose to evaluate the R code chunks in the current working directory after setting options(knitr.use.cwd = TRUE); the default is to evaluate code in the directory of the input document, unless the knitr option opts_knit$set(root.dir = ...) has been set
if options(knitr.digits.signif = TRUE), numbers from inline expressions will be formatted using getOption('digits') as the number of significant digits, otherwise (the default behavior) getOption('digits') is treated as the number of decimal places (thanks, @numatt, #1053)
the chunk option engine.path can also be a list of paths to the engine executables now, e.g., you can set knitr::opts_chunk$set(engine.path = list(python = '/anaconda/bin/python', perl = '/usr/local/bin/perl')), then when a python code chunk is executed, /anaconda/bin/python will be called instead of the system default (rstudio/rmarkdown#812)
introduced a mechanism to protect text output in the sense that it will not be touched by Pandoc during the conversion from R Markdown to another format; this is primarily for package developers to extend R Markdown; see ?raw_output for details (which also shows new functions extract_raw_output() and restore_raw_output())
MAJOR CHANGES
the minimal version of R required for knitr is 3.1.0 now (#1269)
the formatR package is an optional package since the default chunk option tidy = FALSE has been there for a long time; if you use tidy = TRUE, you need to install formatR separately if it is not installed
:set +m is no longer automatically added to haskell code chunks (#1274)
MINOR CHANGES
the package option opts_knit$get('stop_on_error') has been removed
the confusing warning message about knitr::knit2html() when buiding package vignettes using the knitr::rmarkdown engine without pandoc/pandoc-citeproc has been removed (#1286)
the default value of the quiet argument of plot_crop() was changed from !opts_knit$get('progress') to TRUE, i.e., by default the messages from cropping images are suppressed
BUG FIXES
the chunk option cache.vars did not really behave like what was documented (thanks, @simonkth, #1280)
asis_output() should not be merged with normal character output when results='hold' (thanks, @kevinushey, #1310)

CHANGES IN knitr VERSION 1.14
@yihui yihui released this on 12 Aug 2016 · 845 commits to master since this release
NEW FEATURES
improved caching for Rcpp code chunks: the shared library built from the C++ code will be preserved on disk and reloaded the next time if caching is enabled (chunk option cache = TRUE), so that the exported R functions are still usable in later R code chunks; note this feature requires Rcpp >= 0.12.5.6 (thanks, @jjallaire, #1239)
added a helper function all_rcpp_labels(), which is simply all_labels(engine == 'Rcpp') and can be used to extract all chunk lables of Rcpp chunks
added a new engine named sql that uses the DBI package to execute SQL queries, and optionally assign the result to a variable in the knitr session; see http://rmarkdown.rstudio.com/authoring_knitr_engines.html for details (#1241)
fig.keep now accepts numeric values to index low-level plots to keep (#1265)
BUG FIXES
fixed #1211: pandoc('foo.md') generates foo_utf8.html instead of foo.html by default
fixed #1236: include = FALSE for code chunks inside blockquotes did not work (should return > instead of a blank line) (thanks, @fmichonneau)
fixed #1217: define the command \hlipl for syntax highlighting for Rnw documents (thanks, @conjugateprior)
fixed #1215: restoring par() settings might fail when the plot window is partitioned, e.g. par(mfrow = c(1, 2)) (thanks, @jrwishart @jmichaelgilbert)
fixed #1250: in the quiet mode, knit() should not emit the message "processing file ..." when processing child documents (thanks, @KZARCA)
MAJOR CHANGES
knitr will no longer generate screenshots automatically for HTML widgets if the webshot package or PhantomJS is not installed
MINOR CHANGES
if dev = 'cairo_pdf', the cairo_pdf device will be used to record plots (previously the pdf device was used) (#1235)
LaTeX short captions now go up to the first ., : or ; character followed by a space or newline (thanks, @knokknok, #1249)
