About sass
Nine releases of compiler warnings and CRAN checks — the Sass binding is in pure upkeep.
sass compiles Sass to CSS for R, and its recent history is almost entirely about staying installable. The last ten releases are dominated by compilation warnings on new toolchains — Apple Clang 15, gcc-12, Windows — plus R CMD check fixes for r-devel and one LibSass version bump. The only user-visible changes in the set are the switch to woff2 font files in font_google(local = TRUE) and clearer output when Google fonts are downloaded.
