.. warning:: PyMongo 3.12.0 deprecates support for Python 2.7, 3.4 and 3.5.

- PyMongoCrypt 1.1.0 or later is now required for client side field level
encryption support.
- Added :attr:`pymongo.mongo_client.MongoClient.topology_description`.
Notable improvements
....................
- Support for MongoDB Versioned API, see :class:`~pymongo.server_api.ServerApi`.
- Added :attr:`pymongo.mongo_client.MongoClient.topology_description`.
- Added hash support to :class:`~pymongo.mongo_client.MongoClient`,
:class:`~pymongo.database.Database` and
:class:`~pymongo.collection.Collection` (`PYTHON-2466`_).
Bug fixes
.........
- Fixed a bug that could cause the driver to deadlock during automatic
client side field level encryption (`PYTHON-2472`_).
- Fixed a bug that prevented PyMongo from retrying writes after
a ``writeConcernError`` on MongoDB 4.4+ (`PYTHON-2452`_).
- Fixed a memory leak caused by failing SDAM monitor checks on Python 3 (`PYTHON-2433`_).
- Fixed a regression that changed the string representation of
:exc:`~pymongo.errors.BulkWriteError` (`PYTHON-2438`_).
- Fixed a bug that made it impossible to use
:meth:`bson.codec_options.CodecOptions.with_options` and
:meth:`~bson.json_util.JSONOptions.with_options` on some early versions of
Python 3.4 and Python 3.5 due to a bug in the standard library implementation
of :meth:`collections.namedtuple._asdict` (`PYTHON-2440`_).
- Fixed a bug that resulted in a :exc:`TypeError` exception when a PyOpenSSL
socket was configured with a timeout of ``None`` (`PYTHON-2443`_).
- Improved the error message returned by
:meth:`~pymongo.collection.Collection.insert_many` when supplied with an
argument of incorrect type (`PYTHON-1690`_).
