+
+
+### BREAKING CHANGES
+
+* AMBIENT_DIRECTIVES -> PLATFORM_DIRECTIVES
+* AMBIENT_PIPES -> PLATFORM_PIPES
+
+* 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.
