## 2.14.0
### Language
- Add an unsigned shift right operator `>>>`. Pad with zeroes, ignoring the sign
bit. On the web platform `int.>>>` shifts the low 32 bits interpreted as an
unsigned integer, so `a >>> b` gives the same result as
`a.toUnsigned(32) >>> b` on the VM.
- Prior to Dart 2.14, metadata (annotations) were not permitted to be specified
with generic type arguments. This restriction is lifted in Dart Dart 2.14.
```dart
class C<T> {
const C();
}
@C(); // Previously permitted.
@C<int>(); // Previously an error, now permitted.
```
- Prior to Dart 2.14, generic function types were not permitted as arguments to
generic classes or functions, nor to be used as generic bounds. This
restriction is lifted in Dart 2.14.
```dart
T wrapWithLogging<T>(T f) {
if (f is void Function<T>(T x)) {
return <S>(S x) {
print("Call: f<$S>($x)");
var r = f<S>(x);
print("Return: $x");
return r;
} as T;
} // More cases here
return f;
}
void foo<T>(T x) {
print("Foo!");
}
void main() {
// Previously an error, now permitted.
var f = wrapWithLogging<void Function<T>(T)>(foo);
f<int>(3);
}
```
