Performance Improvements
The 1.1 compiler is typically around 4x faster than any previous release. See this blog post for some impressive charts.
Better Module Visibility Rules
TypeScript now only strictly enforces the visibility of types in modules if the --declaration flag is provided. This is very useful for Angular scenarios, for example:
module MyControllers {
interface ZooScope extends ng.IScope {
animals: Animal[];
}
export class ZooController {
// Used to be an error (cannot expose ZooScope), but now is only
// an error when trying to generate .d.ts files
constructor(public $scope: ZooScope) { }
/* more code */
}
}
