Dart Sass 1.0.0-beta.3

• Properly parse numbers with exponents.

• Don't crash when evaluating CSS variables whose names are entirely interpolated (for example, #{--foo}: ...).

Node JS API

• Add support for the importer option to render() and renderSync(). Only synchronous importers are currently supported.

Dart API

• Added an Importer class. This can be extended by users to provide support for custom resolution for @import rules.

• Added built-in FilesystemImporter and PackageImporter implementations that support resolving file: and package: URLs, respectively.

• Added an importers argument to the compile() and compileString() functions that provides Importers to use when resolving @import rules.

• Added a loadPaths argument to the compile() and compileString() functions that provides paths to search for stylesheets when resolving @import rules. This is a shorthand for passing FilesystemImporters to the importers argument.
