* The `new` keyword is optional and can be omitted. Likewise, `const` can be
omitted inside a const context ([issue 30921][].
* **(Breaking)** Functions marked `async` now run synchronously to the first
`await` statement instead of returning to the event loop once at the top of
the function body before any code runs ([issue 30345][]).
* **(Breaking)** Functions marked `async` now run synchronously until the
first `await` statement. Previously, they would return to the event loop

`SCREAMING_CAPS` to `lowercaseWithUnderscores`.
`SCREAMING_CAPS` to `lowerCamelCase`.
* **(Breaking)** Many new methods have been added to core library classes. If
you implement the interfaces of these classes, you will need to implement
the new methods.
* "dart:isolate" and "dart:mirrors" are no longer supported when using Dart
for the web. They are still supported in the command-line VM.
* Dartium is no longer maintained or supported.

* Inference chooses `void` when combining `Object` or `dynamic` and `void`

```dart

var a = [foo(), bar()];

The variable `a` would previously have been inferred as `List<dynamic>`, and
is now be inferred as `List<void>`.
