Dart Sass 1.11 has just been released, and with it a handful of new features. This is an exciting moment, because it marks the first major new feature that’s been added to the language since Dart Sass was launched. It’s also the first release with features that have gone through the new process, from proposal to tests to implementation.
The biggest feature in Dart Sass 1.11 is support for importing plain CSS files. This is a long-awaited feature, and while we’d initially planned on waiting on it until we launched the upcoming module system, we ended up deciding to implement it earlier.
You can now import a CSS file, say
styles.css, just by writing
@import "styles". That file will be parsed as plain CSS, which means that any Sass features like variables or mixins or interpolation will be disallowed. The CSS it defines will become part of your stylesheet, and can be
@extended just like any other styles.
There are a couple caveats: because SCSS is a…

As Dart Sass catches up with Ruby Sass in terms of usability, we’re starting work on adding new features to the language. The first feature we’re looking at is one that’s long been requested by users: adding support for importing plain CSS files without having to rename them to
.scss. Not only do we expect this to be very useful, it’s already partially implemented in LibSass, so this will help bring the implementations more in line with one another.
We’re also trying out a new process with this feature. In order to help keep the behavior of different implementations in sync, we’re starting with a prose specification of the feature before moving on to writing code. We’re also taking this as an opportunity to solicit feedback from you, the Sass community! We want to hear your thoughts on the new feature while we have a chance to revise it based on that feedback.
Historically, the reference implementations of Sass—first Ruby Sass, then Dart Sass—only supported…

With the release of Dart Sass 1.0.0 stable last week, Ruby Sass was officially deprecated. I’ll continue to maintain it over the next year, but when 26 March 2019 rolls around it will reach its official end-of-life. I encourage all users to start migrating away sooner rather than later.

Over the next year, I’ll continue to work on Ruby Sass in a limited capacity. I’ll triage and fix any bugs that are reported, unless they’re minor or obscure enough to be unlikely to pose a practical problem over the next year. I’ll also add support for any new CSS features that require changes to the Sass parser or other parts of the language.
I also won’t be accepting pull requests for new Ruby Sass features. While pull requests are a great way to contribute…

I’ve just uploaded Dart Sass 1.0.0, the very first stable release, to GitHub, npm, Chocolatey, Homebrew, and pub. After working on it for almost two years, I’m thrilled to have a stable release out there and officially ready to use in real-world applications. All the reasons we chose Dart as the implementation language are bearing fruit: Dart Sass is much faster than Ruby Sass, much easier to make available across operating systems and language environments, and much more maintainable.
The 1.0.0 stable release indicates that Dart Sass is fully compatible with the Sass language as defined by the sass-spec test suite, and that its npm package is compatible with the Node Sass API, with the exception of source map support which is coming soon.
I’ve also updated sass-lang.com to cover Dart Sass. The release bar now shows the latest version of all three major implementations, as well as links to their release notes and documentation about each one. The install page covers Dart Sass instead…

I’m excited to announce that I’ve just released the stable version of Sass 3.5. This release focuses on compatibility with new CSS syntax, and helps lay the groundwork for the upcoming module system and compatibility with Dart Sass.
Most of the major features in 3.5 were already in the release candidate, which you can read about here. But there are a handful of other changes that have been added since then:
Sass now supports the the
::slotted()pseudo-element, including extending its selector arguments.
var()function may be safely passed to the CSS color functions
Transparent colors created by Sass’s color functions will now be written as
rgba(0, 0, 0, 0)rather than
transparentto work around a bug in Internet Explorer. Colors written as
transparentin the document will still be emitted as written.
