 * Pub
 
+  * **Breaking:** various commands that previously ran `pub get` implicitly no
+    longer do so. Instead, they merely check to make sure the ".packages" file
+    is newer than the pubspec and the lock file, and fail if it's not.
+
+  * Added support for `--verbosity=error` and `--verbosity=warning`.
+
+  * `pub serve` now collapses multiple GET requests into a single line of
+    output. For full output, use `--verbose`.
+
+  * `pub deps` has improved formatting for circular dependencies on the
+    entrypoint package.
+
   * `pub run` and `pub global run`
 
+    * **Breaking:** to match the behavior of the Dart VM, executables no longer
+      run in checked mode by default. A `--checked` flag has been added to run
+      them in checked mode manually.
+
     * Faster start time for executables that don't import transformed code.
 
     * Binstubs for globally-activated executables are now written in the system
