Angular version 2.2.0 - is now available. This is a minor release following our announced adoption of Semantic Versioning, meaning that it contains no breaking changes and that it is be a drop-in replacement for 2.1.x.
What's new?
You can now AOT compile your Angular 2 Components and Modules when using @angular/upgrade. Check out the upgrade guide on our docs site.
We've added features to the router to assist with version 1.x to 2.x migrations. https://github.com/angular/angular/pull/12160/files
Code generated from AOT compilation (NgFactories) will now be smaller in cases with large numbers of forms. We will continue to improve the size of generated code over time.
We've added guides on using Angular with ES5 and ES6/7.
