Sass makes CSS fun again. Sass is an extension of CSS, adding nested rules, variables, mixins, selector inheritance, and more. It's translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.

Changelog for 3.4.23

(19 December 2016)

  • The Sass logger is now instantiated on a per-thread/per-fiber basis and can now be configured to output to any IO object. This can help services and processes that wrap Sass compilation reliably extract warnings in a concurrent environment.

  • Setting the numeric precision by assigning to Sass::Script::Value::Number.precision is now thread safe. To set for all threads, be sure to set the precision on the main thread.

  • Sass cache files will now be world and group writable if your umask allows it. Issue #1623

  • The supports(...) clause in @import statements now allows bare declarations as per the CSS specification. Issue #1967

  • Fix a bug where, under some circumstances, str-slice() would go to the end of the string even if $end-at was set.

  • Fix conversions between numbers with dpi, dpcm, and dppx units. Previously these conversions were inverted.

  • Support url()s containing quoted strings within unknown directives.
