 - Add to API `DisplayPublisher.publish` two new fully backward-compatible
   keyword-args:
     - `update: bool`
     - `transient: dict`
-- Add  a new dict, `transient`, to message spec for `publish`. For a display
-  data message, `transient` contains data that shouldn't be persisted to files
-  or documents. Add a `display_id` to this `transient` dict by
-  `display(obj, display_id=...)`
+- Support new `transient` key in `display_data` messages spec for `publish`.

+  dict by `display(obj, display_id=...)`
 - Add `ipykernel_launcher` module which removes the current working directory
   from `sys.path` before launching the kernel. This helps to reduce the cases
   where the kernel won't start because there's a `random.py` (or similar)
   module in the current working directory.
-- Add busy/idle messages on IOPub during processing of every kernel request
+- Add busy/idle messages on IOPub during processing of aborted requests
 - Add active event loop setting to GUI, which enables the correct response
   to IPython's `is_event_loop_running_xxx`
-- Add Python 3.6 support
+- Include IPython kernelspec in wheels to reduce reliance on "native kernel
+  spec" in jupyter_client
 - Modify `OutStream` to inherit from `TextIOBase` instead of object to improve
   API support and error reporting
 - Fix IPython kernel death messages at start, such as "Kernel Restarting..."
