Could you also add a ..warning for this like we did for MongoDB 3.6 in pymongo 4.11?

- 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

:attr:`bson.codec_options.TypeRegistry.fallback_encoder` properties

- 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`` parameter to be type ``dict`` instead of ``_CaseInsensitiveDictionary``.

type ``dict`` instead of ``_CaseInsensitiveDictionary``.
