+### Language

+**Breaking Change** [Null
+Safety](https://dart.dev/null-safety/understanding-null-safety) is now enabled
+by default in all packages with a lower sdk constraint of 2.12.0 or greater.
+Files that are not subject to language versioning (whether because they are not
+contained in a pub package, or because the package that they are contained in
+has no lower sdk constraint) are treated as opted into to null safety by default
+and may report new errors.  Pub packages may be opted out of null safety by
+setting a min sdk constraint in pubspec.yaml of 2.9.0 or less.  Files may be
+opted out of null safety by adding `// @dart=2.9` to the beginning of the file.

+  
+  And a corresponding `dart pub remove` that removes dependencies.
+* New option `dart pub outdated --mode=null-safety` that will analyze your
+  dependencies for null-safety.
+* `dart pub publish` will now check your pubspec keys for likely typos.
+* New command `dart pub login` that logs in to pub.dev.
+* The `--server` option to `dart pub publish` and `dart pub uploader` have been
+  deprecated. Use `publish_to` in your `pubspec.yaml` or set the
