.. warning:: PyMongo 4.2 drops support for Python 3.6: Python 3.7+ is now required.
PyMongo 4.2 brings a number of improvements including:
Support for MongoDB 6.0.
Support for the Queryable Encryption beta with MongoDB 6.0. Note that backwards-breaking
changes may be made before the final release. See :ref:automatic-queryable-client-side-encryption for example usage.
Provisional (beta) support for :func:pymongo.timeout to apply a single timeout
to an entire block of pymongo operations.
Added the timeoutMS URI and keyword argument to :class:~pymongo.mongo_client.MongoClient.
Added the :attr:pymongo.errors.PyMongoError.timeout property which is True when
the error was caused by a timeout.
Added the check_exists argument to :meth:~pymongo.database.Database.create_collection
that when True (the default) runs an additional listCollections command to verify that the
collection does not exist already.
Added the following key management APIs to :class:~pymongo.encryption.ClientEncryption:
Support for the crypt_shared library to replace mongocryptd using the new
crypt_shared_lib_path and crypt_shared_lib_required arguments to
:class:~pymongo.encryption_options.AutoEncryptionOpts.
Bug fixes
.........
Fixed a bug where :meth:~pymongo.collection.Collection.estimated_document_count
would fail with a "CommandNotSupportedOnView" error on views (PYTHON-2885_).
Fixed a bug where invalid UTF-8 strings could be passed as patterns for :class:~bson.regex.Regex
objects. :func:bson.encode now correctly raises :class:bson.errors.InvalidStringData (PYTHON-3048_).
Fixed a bug that caused AutoReconnect("connection pool paused") errors in the child
process after fork (PYTHON-3257_).
Fixed a bug where :meth:~pymongo.collection.Collection.count_documents and
:meth:~pymongo.collection.Collection.distinct would fail in a transaction with
directConnection=True (PYTHON-3333_).
GridFS no longer uploads an incomplete files collection document after encountering an
error in the middle of an upload fork. This results in fewer
