BREAKING CHANGE
Previously, the controlsErrors getter of ControlGroup and ControlArray returned the errors of their direct children. This was confusing because the result did not include the errors of nested children (ControlGroup -> ControlGroup -> Control). Making controlsErrors to include such errors would require inventing some custom serialization format, which applications would have to understand.
Since controlsErrors was just a convenience method, and it was causing confusing, we are removing it. If you want to get the errors of the whole form serialized into a single object, you can manually traverse the form and accumulate the errors. This way you have more control over how the errors are serialized.
Closes#5102
BREAKING CHANGE
All private exports from 'angular2/src/core/{directives,pipes,forms}' should be replaced with 'angular2/src/common/{directives,pipes,formis}'
Closes#5153
If the anchor element on which the "router-link" directive is present has a target
attribute other than "_self," the handler will not prevent default behavior of
the browser.

Ambient directives can be configured when bootstraping an application.
Ambient directives can be used in every component of the application without
needing to explicitly list them.
- Changes the `alreadyChecked` flag of AbstractChangeDetector to a new `state` flag.
- Changes all checks of alreadyChecked to check that the state is NeverChecked.
- Set state to Errored if an error is thrown during detection.
- Skip change detection for a detector and its children when the state is Errored.
- Add a test to validate this fixes issue #4323.
Closes#4953
Refactor EventEmitter and Async Facade to match ES7 Observable semantics, properly use RxJS typedefs, make EventEmitter inherit from RxJS Subject. Closes#4149.
BREAKING CHANGE:
- consumers of EventEmitter no longer need to call .toRx()
- EventEmitter is now generic and requires a type - e.g. `EventEmitter<string>`
- EventEmitter and Observable now use the `.subscribe(generatorOrNext, error, complete)` method instead of `.observer(generator)`
- ObservableWrapper uses `callNext/callError/callComplete` instead of `callNext/callThrow/callReturn`
We used to use different external css parsers,
depending on the `DomAdapter`. This lead to
inconsistent behavior and environment specific errors.
Closes#5006Closes#4993
Currently, the only way for a directive to export a validator is by providing a function. This makes it ackward to write validators that depend on directive inputs. In addition to supporting functions as validators, classes implementing the Validator interface are supported too.
- fixes wrapping for object literal keys called `template`.
- spacing in destructuring expressions.
- changes to keep trailing return types of functions closer to their
function declaration.
- better formatting of string literals.
Closes#4828
Example:
var login = new Control("someLogin");
c.setErrors({"notUnique": true});
expect(c.valid).toEqual(false);
expect(c.errors).toEqual({"notUnique": true});
c.updateValue("newLogin");
expect(c.valid).toEqual(true);
BREAKING CHANGE:
Before:
ControlGroup.errors and ControlArray.errors returned a reduced value of their children controls' errors.
After:
ControlGroup.errors and ControlArray.errors return the errors of the group and array.
And ControlGroup.controlsErrors and ControlArray.controlsErrors return the reduce value of their children controls' errors.
