Motor 2.2 adds support for MongoDB 4.4 features. It depends on PyMongo 3.11 or later. Motor continues to support MongoDB 3.0 and later. Motor 2.2 also drops support for Python 2.7 and Python 3.4.
New features:
Added the AsyncIOMotorCursor method ~motor.motor_asyncio.AsyncIOMotorCursor.next that advances the cursor one document at a time, similar to to the AsyncIOMotorChangeStream method ~motor.motor_asyncio.AsyncIOMotorChangeStream.next.
Added index-hinting support to the ~motor.motor_asyncio.AsyncIOMotorCollection.replace_one, ~motor.motor_asyncio.AsyncIOMotorCollection.update_one, ~motor.motor_asyncio.AsyncIOMotorCollection.update_many, ~motor.motor_asyncio.AsyncIOMotorCollection.delete_one, ~motor.motor_asyncio.AsyncIOMotorCollection.delete_many, ~motor.motor_asyncio.AsyncIOMotorCollection.find_one_and_replace, ~motor.motor_asyncio.AsyncIOMotorCollection.find_one_and_update, and ~motor.motor_asyncio.AsyncIOMotorCollection.find_one_and_delete methods.
Added support for the allow_disk_use parameter to ~motor.motor_asyncio.AsyncIOMotorCollection.find.
Modified the ~motor.motor_asyncio.AsyncIOMotorChangeStream class' async context manager such that the change stream cursor is now created during the call to async with. Previously, the cursor was only created when the application iterated the ~motor.motor_asyncio.AsyncIOMotorChangeStream object which could result in the application missing some changes.
Motor now advertises the framework used by the application to the MongoDB server as asyncio or Tornado. Previously, no framework information was reported if the application used asyncio.
Bug-fixes:
Fixed a bug that caused calls to the ~motor.motor_asyncio.AsyncIOMotorGridOut.open() method to raise AttributeError.
Fixed a bug that sometimes caused ~asyncio.Future.set_result to be called on a cancelled ~asyncio.Future when iterating a ~motor.motor_asyncio.AsyncIOMotorCommandCursor.
Deprecations:
Deprecated AsyncIOMotorCursor method ~motor.motor_asyncio.AsyncIOMotorCursor.next_object and property ~motor.motor_asyncio.AsyncIOMotorCursor.fetch_next. Applications should use async for to iterate over cursors instead.
Deprecated the ~motor.motor_asyncio.AsyncIOMotorClient.fsync method. Applications should run the fsync command directly with ~motor.motor_asyncio.AsyncIOMotorDatabase.command instead.
Motor 2.1 adds support for MongoDB 4.2 features. It depends on PyMongo 3.10 or later. Motor continues to support MongoDB 3.0 and later. Motor 2.1 also adds support for Python 3.8.
Motor now offers experimental support for Windows when it is using the asyncio event loop. This means it supports Windows exclusively with Python 3, either integrating with asyncio directly or with Tornado 5 or later: starting in version 5, Tornado uses the asyncio event loop on Python 3 by default.
Additional changes:
Support for MongoDB 4.2 sharded transactions. Sharded transactions have the same API as replica set transactions.
New method ~motor.motor_asyncio.AsyncIOMotorClientSession.with_transaction to support conveniently running a transaction in a session with automatic retries and at-most-once semantics.
Added the max_commit_time_ms parameter to ~motor.motor_asyncio.AsyncIOMotorClientSession.start_transaction.
The retryWrites URI option now defaults to True. Supported write operations that fail with a retryable error will automatically be retried one time, with at-most-once semantics.
Support for retryable reads and the retryReads URI option which is enabled by default. See the ~pymongo.mongo_client.MongoClient documentation for details. Now that supported operations are retried automatically and transparently, users should consider adjusting any custom retry logic to prevent an application from inadvertently retrying for too long.
Support zstandard for wire protocol compression.
Support for periodically polling DNS SRV records to update the mongos proxy list without having to change client configuration.
New method motor.motor_asyncio.AsyncIOMotorDatabase.aggregate to support running database level aggregations.
Change stream enhancements for MongoDB 4.2:
Resume tokens can now be accessed from a AsyncIOMotorChangeStream cursor using the ~motor.motor_asyncio.AsyncIOMotorChangeStream.resume_token attribute.
New AsyncIOMotorChangeStream method ~motor.motor_asyncio.AsyncIOMotorChangeStream.try_next and attribute ~motor.motor_asyncio.AsyncIOMotorChangeStream.alive.
