Improving client-side performance wasn't the only focus of the new release, either. Ladd said there is growing interest in using Dart for server-side applications – presumably, because it's easy to run Dart VM on a server, among other reasons – and Dart 1.1 includes a number of new features designed to accommodate this.
The new release now supports large files, file copying, process signal handlers, accessing output terminal information, and the UDP networking protocol – the latter of which should make it easier to write streaming media applications in Dart.
In addition, Dart's HTTP stack has been optimized since the last release, latency has been decreased for many I/O operations, and performance of asynchronous operations has been improved.
Dart 1.1 also bundles a souped-up Dart Editor that improves debugging and code completion and offers more descriptive tooltips, in addition to various performance enhancements.
If you're the type who prefers to just dive right in, however, you can download all of the updated tools, including dart2js and the improved Dart Editor, from the Dart homepage, here. ®
