[Bruce Dubbs]

New point version.

Fixes

    Revert sass2scss@v1.1.2 update (@xzyfer, #2637 #2638)

Breaking

This breaking change was unintentionally released early. However since this is the desired behaviour moving forward we're going to roll-forward with it.
Raw CSS @imports

This is a non-standard, and confusion feature. Implementors can now
opt into supporting @importing additional file extensions with
sass_option_push_import_extension.

An @import that resolves to a .css file will produce a deprecation
warning. This deprecation messaage will be removed in the upcoming 3.6
release.

DEPRECATION WARNING on line 1, column 8 of /libsass/test.scss:
Including .css files with @import is non-standard behaviour which will be removed in future versions of LibSass.
Use a custom importer to maintain this behaviour. Check your implementations documentation on how to create a custom importer.

3.5.6

    Allow ! in custom property values.

    var() may now be passed in place of multiple arguments to rgb(), rgba(), hsl() and hsla().

    Don't crash on custom properties that aren't followed by semicolons.

    Don't crash when normalizing numbers with complex units.

    Don't crash on $x % 0.

[Douglas R. Reno]

Sassc-3.5.0 is still the current version. This is confusing.
