"A year ago we released a technology preview of Dart, a project that includes a modern language, libraries and tools for building complex web applications," Google's Lars Bak wrote.
"Today, after plowing through thousands of bug reports and feature requests from the web community, a new, more stable and comprehensive version of Dart is now available and ready to use," he said.
Also new is an editor dedicated completely to Dart, to make it easier to write and debug Dart code. This goes hand in hand with Dartium, a version of Chrome/Chromium that natively supports the programming language.
The new Dart SDK also comes with Pub, a new package manager, and a server-side I/O library if you want to use Dart for server apps, Node.js style.
If you're looking to get started with Dart or just want to check it out, the Dart Editor is a good place to start. It comes with the SDK and Dartium built in, so the Editor is all you need to get coding.
