knitr 1.40
24 Aug 15:39
NEW FEATURES
* Added a function convert_chunk_header() to convert the old in-header chunk
options to the new in-body chunk options (#2149#2151).
* Added a new "graphics device", dev = "gridSVG", which uses
gridSVG::grid.export() to export grid graphics to SVG (thanks, @jooyoungseo
, #2152).
* Added a new engine eviews, which calls the EviewsR package to execute
EViews code (thanks, @sagirumati, #2158).
* Added support for a php engine like other engines for interpreted
languages. It will call php -r <code>, with <code> being the chunk content
(thanks, @ralmond, #2144).
* Per suggestion of @jakubkaczor (#2116) and discussion with @pedropark99 (#
2140), the chunk option fig.sep can also be used to add LaTeX code before
the first sub-figure now. Previously this option can only be used for
adding LaTeX code after each sub-figure.
* knitr::kable() supports tabularx and xltabular environments now for LaTeX
tables, e.g., knitr::kable(head(iris), format = 'latex', tabular =
'tabularx') (thanks, @amarakon, #2138).
* For HTML output formats of R Markdown, SVG plots (e.g., in case of chunk
option dev = 'svg' or dev = 'gridSVG') can be embedded differently now when
options(knitr.svg.object = TRUE): if the HTML output is self-contained, the
raw SVG code will be embedded directly in HTML, otherwise the .svg file is
embedded in the <object> tag. By default, this feature is not enabled,
i.e., the default is options(knitr.svg.object = FALSE) for
backward-compatibility, which means the <img> tag is used for SVG plots
just like other plot formats. This new feature will make assistive
technology agents, such as screen readers, interact with SVG plots (thanks,
@jooyoungseo, #2152).

MAJOR CHANGES
* Added an argument rel_path to include_graphics(), which defaults to TRUE,
meaning that this function will try to convert absolute paths to relative
paths automatically. If the conversion fails, it will issue a warning. If
you want to suppress the conversion (and the warning), you may use rel_path
= FALSE or set the global option options(knitr.graphics.rel_path = FALSE).
In the previous version of knitr, this function would always issue a
warning when it detects absolute paths (thanks, @davidski @kendavidn, #2119
).
