@@ -13,11 +13,26 @@ PyMongo 4.2 brings a number of improvements including:
   changes may be made before the final release.  See :ref:`automatic-queryable-client-side-encryption` for example usage.
 - Provisional (beta) support for :func:`pymongo.timeout` to apply a single timeout
   to an entire block of pymongo operations.
+- Added the ``timeoutMS`` URI and keyword argument to :class:`~pymongo.mongo_client.MongoClient`.
 - Added the :attr:`pymongo.errors.PyMongoError.timeout` property which is ``True`` when
   the error was caused by a timeout.
-- Added ``check_exists`` option to :meth:`~pymongo.database.Database.create_collection`
+- Added the ``check_exists`` argument to :meth:`~pymongo.database.Database.create_collection`
   that when True (the default)  runs an additional ``listCollections`` command to verify that the
   collection does not exist already.
+- Added the following key management APIs to :class:`~pymongo.encryption.ClientEncryption`:
+
+  - :meth:`~pymongo.encryption.ClientEncryption.get_key`
+  - :meth:`~pymongo.encryption.ClientEncryption.get_keys`
+  - :meth:`~pymongo.encryption.ClientEncryption.delete_key`
+  - :meth:`~pymongo.encryption.ClientEncryption.add_key_alt_name`
+  - :meth:`~pymongo.encryption.ClientEncryption.get_key_by_alt_name`
+  - :meth:`~pymongo.encryption.ClientEncryption.remove_key_alt_name`
+  - :meth:`~pymongo.encryption.ClientEncryption.rewrap_many_data_key`
+  - :class:`~pymongo.encryption.RewrapManyDataKeyResult`
+
+- Support for the ``crypt_shared`` library to replace ``mongocryptd`` using the new
+  ``crypt_shared_lib_path`` and ``crypt_shared_lib_required`` arguments to
+  :class:`~pymongo.encryption_options.AutoEncryptionOpts`.

+  :class:`~gridfs.errors.CorruptGridFile` errors (`PYTHON-1552`_).
+- Renamed PyMongo's internal C extension methods to avoid crashing due to name conflicts

 Unavoidable breaking changes

   Users of the Stable API with estimated_document_count are recommended to upgrade
   their server version to 5.0.9+ or set :attr:`pymongo.server_api.ServerApi.strict`
   to ``False`` to avoid encountering errors (`PYTHON-3167`_).
+- Removed generic typing from :class:`~pymongo.client_session.ClientSession` to improve
+  support for Pyright (`PYTHON-3283`_).
+- Added ``__all__`` to the bson, pymongo, and gridfs packages. This could be a breaking
+  change for apps that relied on ``from bson import *`` to import APIs not present in
