   experiments in the Dart VM (and language).
+* Warn when publishing the first null-safe version of a package.
+* `pub outdated`:
+  * Introduce `--mode=null-safety` flag that will report which of your
+    dependencies you can upgrade to fully support null safety.
+  * If the current version of a dependency is a prerelease
+    version, use prereleases for latest if there is no newer stable.
+  * Don't require a `pubspec.lock` file. When the lockfile is missing, the
+    **Current** column is empty.
