+### Performance Improvements
+
+* use abstract keyword where possible to decrease file size. ([#14112](https://github.com/angular/angular/issues/14112)) ([670b680](https://github.com/angular/angular/commit/670b680))

+
+
+### BREAKING CHANGES
+
+* common: A definition of `Iterable<T>` is now required to correctly compile
+Angular applications. Support for `Iterable<T>` is not required at
+runtime but a type definition `Iterable<T>` must be available.
+
+`NgFor`, and now `NgForOf<T>`, already supports `Iterable<T>` at
+runtime. With this change the type definition is updated to reflect
+this support.
+
+Migration:
+- add "es2015.iterable.ts" to your tsconfig.json "libs" fields.
+
+Part of #12398
+* upgrade: Previously, `upgrade/static/downgradeInjectable` returned an array of the form:
+
+```js
+['dep1', 'dep2', ..., function factory(dep1, dep2, ...) { ... }]
+```
+
+Now it returns a function with an `$inject` property:
+
+```js
+factory.$inject = ['dep1', 'dep2', ...];
+function factory(dep1, dep2, ...) { ... }
+```
+
+It shouldn't affect the behavior of apps, since both forms are equally suitable
+to be used for registering AngularJS injectable services, but it is possible
+that type-checking might fail or that current code breaks if it relies on the
+returned value being an array.
