• Fix a stack imbalance bug

• Windows: use libpng included with Rtools on R 4.2 and up.
• Add support for dev.capabilities()

• Fix <cstdint> include at request of CRAN

• Add new graphics engine features:

  • Path clipping
  • Masking
  • Pattern and gradient fills

• Font family names are now quoted (#136)

• svglite now renders leading white-space in nodes. (#131, @hrbrmstr)

• svglite now uses systemfonts for text metric calculations and font family
  lookup.

• svglite can now encode OpenType font features into the CSS if the used font
  contains registered features

• svglite now directly encodes raster data into png instead of rendering it
  through cairo. If the provided raster is smaller than the final requested size
  it will be resized.

• SVG's can now get a top-level id so that style definitions doesn't spill into
  the surrounding HTML (#91)

• Dimensions are now encoded into the top-level <svg> tag (#90)

• Starting a new page creates a new file if the filename supports it (#98, @vandenman).

• The inline devices now defaults to the same dimensions as svglite() (#89)

• Clip defs are now only written if they don't already exist (#110)

• Clipping is now defined with outer groups instead of on each element (#109)

• svglite now uses cpp11 instead of Rcpp (#100)

• svgz output is now supported natively (#6)

• Text adjustments are now encoded in css where possible (#107)

• The use of textLength CSS property can now be turned off (#118)

• web font imports can now be given when creating an svg (#108)

• Add scaling argument to devices to control line-width and text scaling (#115)

• svg files that are being written are now only valid at all times if always_valid
  is set to TRUE in the svglite() call.

• svglite now guards against attempts at writing to the device before a new page
  has been requested (#126)

• The radius of circles is no longer expressed in pt (#93, @vandenman).

• Dimensions smaller than 1 now retain two significant figures (#94, @ilia-kats).

• @thomasp85 takes over as maintainer

• Improvements to reproducibility of generated SVGs: Negative zeros
  are now treated as positive, and the clip ID are now generated from
  truncated elements.

• svglite now uses the polygon SVG element. This ensures that
  polygons are properly closed (#82).

• Text metrics are now correctly computed for Unicode characters in
  plotmath expressions (#81).

• This release makes svglite compatible with gdtools 0.1.6.

New features

• The device functions gain system_fonts and user_fonts arguments.
• Two new vignettes: vignette("fonts") and vignette("scaling"). The vignette on fonts explains in detail how to use the new fonts arguments and why. The vignette on scaling goes over scaling issues, e.g. when embedding svglite outputs in a web page.
• xmlSVG() gains height and width arguments (#66).
• New stringSVG() device function for quick testing.

Improvements

• Greatly improves the performance of svgstring() (#58).
• Clip paths now get a unique identifier to avoid collisions when multiple plots are included in a document (#67).
• Raster graphics are now correctly cropped (#64) and handle transparency properly.
• The dimensions of text fields are now hardcoded in the SVGs to prevent alignment issues.

Bug fixes

• editSVG() works again (#56).
• The dashes in lines with lwd < 1 are scaled better (#68).
• Transparent blacks are written correctly (#62, #63).
• Text is now scaled correctly (#72, #59). See also the new vignette on scaling.

• Text metrics now converted from points to pixels (#45, #48) - this
  fixes text alignment issues.
• Intermediate outputs are always valid SVG (#53).
• New svgstring() returns plot as a string (#40, @yixuan).
• Use raster test compatible with older versions of R.
• Add support for clip(). This also fixes a number of minor issues with
  grid graphics (@yixuan, #47 and #49).
• Fix incorrect device size (#50).
