Release Notes

dart-lang/sdk (js)

v0.7.0

• Remove dependency on dart:js.
• Update SDK lower constraint to 3.1.0-66.0.dev.
• Update SDK upper constraint to 4.0.0.
• Breaking Change: Moved annotations to single location in
  dart:_js_annotations. This makes it easier to avoid collisions with
  dart:js_interop's @JS, as you will now see a static error instead of it
  resolving in favor of the package definition. However, since this may result
  in breakages in previously working code, this is treated as a breaking change.
