@@ -10,6 +10,7 @@ PyMongo 4.14 brings a number of changes including:
 - 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.
