+
+### BREAKING CHANGES
+
+#### ControlGroup.errors and ControlArray.errors have changed
+
+* 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.
+
+#### Errors format has changed from validators
+
+Now errors from a control or an array's children are prefixed with 'controls' while errors from the object itself are left at the root level.
+
+**Example:**
+Given a Control group as follows:
+```
+var group = new ControlGroup({
+  login: new Control("", required),
+  password: new Control("", required),
+  passwordConfirm: new Control("", required)
+});
+```
+
+*Before:*
+```
+group.errors
+{
+  login: {required: true},
+  password: {required: true},
+  passwordConfirm: {required: true},
+}
+```
+
+*After:*
+```
+group.errors
+{
+  controls: {
+    login: {required: true},
+    password: {required: true},
+    passwordConfirm: {required: true},
+  }
+}
+```
+
+#### Pipes are now associated right to left
+
+* Before: `1 + 1 | pipe:a | pipe:b` was parsed as `(1 + 1) | pipe:(a | pipe:b)`
+* After: `1 + 1 | pipe:a | pipe:b` is parsed as `((1 + 1) | pipe:a) | pipe:b`
+
+#### NgZone Moved to Stream/Observable-based callback API
+
+* deprecates these methods in NgZone: overrideOnTurnStart, overrideOnTurnDone, overrideOnEventDone, overrideOnErrorHandler
+* introduces new API in NgZone that may shadow other API used by existing applications.
+
+#### Directives no longer match to variable names
+
+You can no longer use a #foo or a var-foo to apply directive [foo], although it didn't work properly anyway.
+This commit is fixing breakage caused by the switch to pre-compiler (exact SHA unknown).
+
+#### Actions no longer support if statements
