Changes in Version 4.14.0 (XXXX/XX/XX)
Changes in Version 4.14.0 (2025/08/06)
--------------------------------------
.. warning:: PyMongo 4.14 drops support for MongoDB 4.0. PyMongo now supports
MongoDB 4.2+.
PyMongo 4.14 brings a number of changes including:
- Added preliminary support for Python 3.14 and 3.14 with free-threading. We do not yet support the following with Python 3.14:
- Subinterpreters (``concurrent.interpreters``)
- Free-threading with Encryption
- mod_wsgi
- Removed experimental support for free-threading support in Python 3.13.
- Added :attr:`bson.codec_options.TypeRegistry.codecs` and :attr:`bson.codec_options.TypeRegistry.fallback_encoder` properties
to allow users to directly access the type codecs and fallback encoder for a given :class:`bson.codec_options.TypeRegistry`.
- Added :meth:`pymongo.asynchronous.mongo_client.AsyncMongoClient.append_metadata` and
:meth:`pymongo.mongo_client.MongoClient.append_metadata` to allow instantiated MongoClients to send client metadata
on-demand
- Improved performance of selecting a server with the Primary selector.
- Dropped support for MongoDB 4.0.
- Added preliminary support for Python 3.14 and 3.14 with free-threading. We do
not yet support the following with Python 3.14:
- Introduces a minor breaking change. When encoding :class:`bson.binary.BinaryVector`, a ``ValueError`` will be raised
if the 'padding' metadata field is < 0 or > 7, or non-zero for any type other than PACKED_BIT.
- Changed :meth:`~pymongo.uri_parser.parse_uri`'s ``options`` parameter to be type ``dict`` instead of ``_CaseInsensitiveDictionary``.
- Subinterpreters (``concurrent.interpreters``)
- Free-threading with Encryption
- mod_wsgi
- Removed experimental support for free-threading support in Python 3.13.
- Added :attr:`bson.codec_options.TypeRegistry.codecs` and
:attr:`bson.codec_options.TypeRegistry.fallback_encoder` properties
to allow users to directly access the type codecs and fallback encoder for a
given :class:`bson.codec_options.TypeRegistry`.
- Added
:meth:`pymongo.asynchronous.mongo_client.AsyncMongoClient.append_metadata` and
:meth:`pymongo.mongo_client.MongoClient.append_metadata` to allow instantiated
MongoClients to send client metadata on-demand
- Improved performance of selecting a server with the Primary selector.
- Introduces a minor breaking change. When encoding
:class:`bson.binary.BinaryVector`, a ``ValueError`` will be raised if the
'padding' metadata field is < 0 or > 7, or non-zero for any type other than
PACKED_BIT.
- Changed :meth:`~pymongo.uri_parser.parse_uri`'s ``options`` return value to be
type ``dict`` instead of ``_CaseInsensitiveDictionary``.
