- update to 3.11.1:
- Support for Python 3.9.
- Initial support for Azure and GCP KMS providers for client side field level
encryption is in beta. See the docstring for
:class:`~pymongo.mongo_client.MongoClient`,
:class:`~pymongo.encryption_options.AutoEncryptionOpts`,
and :mod:`~pymongo.encryption`. **Note: Backwards-breaking changes may be
made before the final release.**
- Fixed a bug where the :class:`bson.json_util.JSONOptions` API did not match
the :class:`bson.codec_options.CodecOptions` API due to the absence of
a :meth:`bson.json_util.JSONOptions.with_options` method. This method has now
been added.
- Fixed a bug which made it impossible to serialize
:class:`~pymongo.errors.BulkWriteError` instances using :mod:`pickle`.
- Fixed a bug wherein PyMongo did not always discard an implicit session after
encountering a network error.
- Fixed a bug where connections created in the background were not
authenticated.
- Fixed a memory leak in the :mod:`bson` module when using a
:class:`~bson.codec_options.TypeRegistry`.
