py-mongo: updated to 3.12.0

Changes in Version 3.12.0
-------------------------

.. warning:: PyMongo 3.12.0 deprecates support for Python 2.7, 3.4 and 3.5.
   These Python versions will not be supported by PyMongo 4.

.. warning:: PyMongo now allows insertion of documents with keys that include
   dots ('.') or start with dollar signs ('$').

- PyMongoCrypt 1.1.0 or later is now required for client side field level
  encryption support.

Notable improvements
....................

- Added support for MongoDB 5.0.
- Support for MongoDB Versioned API, see :class:`~pymongo.server_api.ServerApi`.
- Support for snapshot reads on secondaries (see :ref:`snapshot-reads-ref`).
- Support for Azure and GCP KMS providers for client side field level
  encryption. See the docstring for :class:`~pymongo.mongo_client.MongoClient`,
  :class:`~pymongo.encryption_options.AutoEncryptionOpts`,
  and :mod:`~pymongo.encryption`.
- Support AWS authentication with temporary credentials when connecting to KMS
  in client side field level encryption.
- Support for connecting to load balanced MongoDB clusters via the new
  ``loadBalanced`` URI option.
- Support for creating timeseries collections via the ``timeseries`` and
  ``expireAfterSeconds`` arguments to
  :meth:`~pymongo.database.Database.create_collection`.
- Added :attr:`pymongo.mongo_client.MongoClient.topology_description`.
- Added hash support to :class:`~pymongo.mongo_client.MongoClient`,
  :class:`~pymongo.database.Database` and
  :class:`~pymongo.collection.Collection` (`PYTHON-2466`_).
- Improved the error message returned by
  :meth:`~pymongo.collection.Collection.insert_many` when supplied with an
  argument of incorrect type (`PYTHON-1690`_).
- Added session and read concern support to
  :meth:`~pymongo.collection.Collection.find_raw_batches`
  and :meth:`~pymongo.collection.Collection.aggregate_raw_batches`.

Bug fixes
.........

- Fixed a bug that could cause the driver to deadlock during automatic
  client side field level encryption (`PYTHON-2472`_).
- Fixed a potential deadlock when garbage collecting an unclosed exhaust
  :class:`~pymongo.cursor.Cursor`.
- Fixed an bug where using gevent.Timeout to timeout an operation could
  lead to a deadlock.
- Fixed the following bug with Atlas Data Lake. When closing cursors,
  pymongo now sends killCursors with the namespace returned the cursor's
  initial command response.
- Fixed a bug in :class:`~pymongo.cursor.RawBatchCursor` that caused it to
  return an empty bytestring when the cursor contained no results. It now
  raises :exc:`StopIteration` instead.

Deprecations
............

- Deprecated support for Python 2.7, 3.4 and 3.5.
- Deprecated support for database profiler helpers
  :meth:`~pymongo.database.Database.profiling_level`,
  :meth:`~pymongo.database.Database.set_profiling_level`,
  and :meth:`~pymongo.database.Database.profiling_info`. Instead, users
  should run the `profile command`_ with the
  :meth:`~pymongo.database.Database.command` helper directly.
- Deprecated :exc:`~pymongo.errors.NotMasterError`. Users should
  use :exc:`~pymongo.errors.NotPrimaryError` instead.
- Deprecated :class:`~pymongo.ismaster.IsMaster` and :mod:`~pymongo.ismaster`
  which will be removed in PyMongo 4.0 and are replaced by
  :class:`~pymongo.hello.Hello` and :mod:`~pymongo.hello` which provide the
  same API.
- Deprecated the :mod:`pymongo.messeage` module.
- Deprecated the ``ssl_keyfile`` and ``ssl_certfile`` URI options in favor
  of ``tlsCertificateKeyFile`` (see :doc:`examples/tls`).

py-mongo: updated to 3.11.4

Version 3.11.4 fixes a bug where a MongoClient would mistakenly attempt to
create minPoolSize connections to arbiter nodes (`PYTHON-2634`_).

Log message:
py-mongo: updated to 3.11.3

Changes in Version 3.11.3
-------------------------

Issues Resolved

Version 3.11.3 fixes a bug that prevented PyMongo from retrying writes after
a ``writeConcernError`` on MongoDB 4.4+

Log message:
py-mongo: updated to 3.11.2

Changes in Version 3.11.2

Issues Resolved
Version 3.11.2 includes a number of bugfixes. Highlights include:

Fixed a memory leak caused by failing SDAM monitor checks on Python 3 (PYTHON-2433).
Fixed a regression that changed the string representation of BulkWriteError \ 
(PYTHON-2438).
Fixed a bug that made it impossible to use \ 
bson.codec_options.CodecOptions.with_options() and with_options() on some early \ 
versions of Python 3.4 and Python 3.5 due to a bug in the standard library \ 
implementation of collections.namedtuple._asdict() (PYTHON-2440).
Fixed a bug that resulted in a TypeError exception when a PyOpenSSL socket was \ 
configured with a timeout of None (PYTHON-2443).

Changes in Version 3.11.1
Version 3.11.1 adds support for Python 3.9 and includes a number of bugfixes. \ 
Highlights include:

Support for Python 3.9.
Initial support for Azure and GCP KMS providers for client side field level \ 
encryption is in beta. See the docstring for MongoClient, AutoEncryptionOpts, \ 
and encryption. Note: Backwards-breaking changes may be made before the final \ 
release.
Fixed a bug where the bson.json_util.JSONOptions API did not match the \ 
bson.codec_options.CodecOptions API due to the absence of a \ 
bson.json_util.JSONOptions.with_options() method. This method has now been \ 
added.
Fixed a bug which made it impossible to serialize BulkWriteError instances using \ 
pickle.
Fixed a bug wherein PyMongo did not always discard an implicit session after \ 
encountering a network error.
Fixed a bug where connections created in the background were not authenticated.
Fixed a memory leak in the bson module when using a TypeRegistry.

Changes in Version 3.11.0

Version 3.11 adds support for MongoDB 4.4 and includes a number of bug fixes. \ 
Highlights include:

Support for OCSP (Online Certificate Status Protocol).
Support for PyOpenSSL as an alternative TLS implementation. PyOpenSSL is \ 
required for OCSP support. It will also be installed when using the “tls” \ 
extra if the version of Python in use is older than 2.7.9.
Support for the MONGODB-AWS authentication mechanism.
Support for the directConnection URI option and kwarg to MongoClient.
Support for speculative authentication attempts in connection handshakes which \ 
reduces the number of network roundtrips needed to authenticate new connections \ 
on MongoDB 4.4+.
Support for creating collections in multi-document transactions with \ 
create_collection() on MongoDB 4.4+.
Added index hinting support to the replace_one(), update_one(), update_many(), \ 
find_one_and_replace(), find_one_and_update(), delete_one(), delete_many(), and \ 
find_one_and_delete() commands.
Added index hinting support to the ReplaceOne, UpdateOne, UpdateMany, DeleteOne, \ 
and DeleteMany bulk operations.
Added support for bson.binary.UuidRepresentation.UNSPECIFIED and \ 
MongoClient(uuidRepresentation='unspecified') which will become the default UUID \ 
representation starting in PyMongo 4.0. See Handling UUID Data for details.
Added the background parameter to \ 
pymongo.database.Database.validate_collection(). For a description of this \ 
parameter see the MongoDB documentation for the validate command.
Added the allow_disk_use parameters to pymongo.collection.Collection.find().
Added the hedge parameter to PrimaryPreferred, Secondary, SecondaryPreferred, \ 
Nearest to support disabling (or explicitly enabling) hedged reads in MongoDB \ 
4.4+.
Fixed a bug in change streams that could cause PyMongo to miss some change \ 
documents when resuming a stream that was started without a resume token and \ 
whose first batch did not contain any change documents.
Fixed an bug where using gevent.Timeout to timeout an operation could lead to a \ 
deadlock.

Deprecations:

Deprecated the oplog_replay parameter to pymongo.collection.Collection.find(). \ 
Starting in MongoDB 4.4, the server optimizes queries against the oplog \ 
collection without requiring the user to set this flag.
Deprecated pymongo.collection.Collection.reindex(). Use command() to run the \ 
reIndex command instead.
Deprecated pymongo.mongo_client.MongoClient.fsync(). Use command() to run the \ 
fsync command instead.
Deprecated pymongo.mongo_client.MongoClient.unlock(). Use command() to run the \ 
fsyncUnlock command instead. See the documentation for more information.
Deprecated pymongo.mongo_client.MongoClient.is_locked. Use command() to run the \ 
currentOp command instead. See the documentation for more information.

Unavoidable breaking changes:

GridFSBucket and GridFS do not support multi-document transactions. Running a \ 
GridFS operation in a transaction now always raises the following error: \ 
InvalidOperation: GridFS does not support multi-document transactions

Log message:
py-mongo: updated to 3.10.1

Changes in Version 3.10.1
-------------------------

Version 3.10.1 fixes the following issues discovered since the release of
3.10.0:

- Fix a TypeError logged to stderr that could be triggered during server
  maintenance or during :meth:`pymongo.mongo_client.MongoClient.close`.
- Avoid creating new connections during
  :meth:`pymongo.mongo_client.MongoClient.close`.

https://jira.mongodb.org/secure/ReleaseNote.jspa?projectId=10004&version=25039

Changes in Version 3.10.0
-------------------------

Version 3.10 includes a number of improvements and bug fixes. Highlights
include:

- Support for Client-Side Field Level Encryption with MongoDB 4.2. See
  :doc:`examples/encryption` for examples.
- Support for Python 3.8.
- Added :attr:`pymongo.client_session.ClientSession.in_transaction`.
- Do not hold the Topology lock while creating connections in a MongoClient's
  background thread. This change fixes a bug where application operations would
  block while the background thread ensures that all server pools have
  minPoolSize connections.
- Fix a UnicodeDecodeError bug when coercing a PyMongoError with a non-ascii
  error message to unicode on Python 2.
- Fix an edge case bug where PyMongo could exceed the server's
  maxMessageSizeBytes when generating a compressed bulk write command.

Changes in Version 3.9.0
------------------------

Version 3.9 adds support for MongoDB 4.2. Highlights include:

- Support for MongoDB 4.2 sharded transactions. Sharded transactions have
  the same API as replica set transactions. See :ref:`transactions-ref`.
- New method :meth:`pymongo.client_session.ClientSession.with_transaction` to
  support conveniently running a transaction in a session with automatic
  retries and at-most-once semantics.
- Initial support for client side field level encryption. See the docstring for
  :class:`~pymongo.mongo_client.MongoClient`,
  :class:`~pymongo.encryption_options.AutoEncryptionOpts`,
  and :mod:`~pymongo.encryption` for details. **Note: Support for client side
  encryption is in beta. Backwards-breaking changes may be made before the
  final release.**
- Added the ``max_commit_time_ms`` parameter to
  :meth:`~pymongo.client_session.ClientSession.start_transaction`.
- Implement the `URI options specification`_ in the
  :meth:`~pymongo.mongo_client.MongoClient` constructor. Consequently, there are
  a number of changes in connection options:

    - The ``tlsInsecure`` option has been added.
    - The ``tls`` option has been added. The older ``ssl`` option has been retained
      as an alias to the new ``tls`` option.
    - ``wTimeout`` has been deprecated in favor of ``wTimeoutMS``.
    - ``wTimeoutMS`` now overrides ``wTimeout`` if the user provides both.
    - ``j`` has been deprecated in favor of ``journal``.
    - ``journal`` now overrides ``j`` if the user provides both.
    - ``ssl_cert_reqs`` has been deprecated in favor of \ 
``tlsAllowInvalidCertificates``.
      Instead of ``ssl.CERT_NONE``, ``ssl.CERT_OPTIONAL`` and \ 
``ssl.CERT_REQUIRED``, the
      new option expects a boolean value - ``True`` is equivalent to \ 
``ssl.CERT_NONE``,
      while ``False`` is equivalent to ``ssl.CERT_REQUIRED``.
    - ``ssl_match_hostname`` has been deprecated in favor of \ 
``tlsAllowInvalidHostnames``.
    - ``ssl_ca_certs`` has been deprecated in favor of ``tlsCAFile``.
    - ``ssl_certfile`` has been deprecated in favor of ``tlsCertificateKeyFile``.
    - ``ssl_pem_passphrase`` has been deprecated in favor of \ 
``tlsCertificateKeyFilePassword``.
    - ``waitQueueMultiple`` has been deprecated without replacement. This option
      was a poor solution for putting an upper bound on queuing since it didn't
      affect queuing in other parts of the driver.
- 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 :class:`~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 :meth:`pymongo.database.Database.aggregate` to support running
  database level aggregations.
- Support for publishing Connection Monitoring and Pooling events via the new
  :class:`~pymongo.monitoring.ConnectionPoolListener` class. See
  :mod:`~pymongo.monitoring` for an example.
- :meth:`pymongo.collection.Collection.aggregate` and
  :meth:`pymongo.database.Database.aggregate` now support the ``$merge`` pipeline
  stage and use read preference
  :attr:`~pymongo.read_preferences.ReadPreference.PRIMARY` if the ``$out`` or
  ``$merge`` pipeline stages are used.
- Support for specifying a pipeline or document in
  :meth:`~pymongo.collection.Collection.update_one`,
  :meth:`~pymongo.collection.Collection.update_many`,
  :meth:`~pymongo.collection.Collection.find_one_and_update`,
  :meth:`~pymongo.operations.UpdateOne`, and
  :meth:`~pymongo.operations.UpdateMany`.
- New BSON utility functions :func:`~bson.encode` and :func:`~bson.decode`
- :class:`~bson.binary.Binary` now supports any bytes-like type that implements
  the buffer protocol.
- Resume tokens can now be accessed from a ``ChangeStream`` cursor using the
  :attr:`~pymongo.change_stream.ChangeStream.resume_token` attribute.
- Connections now survive primary step-down when using MongoDB 4.2+.
  Applications should expect less socket connection turnover during
  replica set elections.

Unavoidable breaking changes:

- Applications that use MongoDB with the MMAPv1 storage engine must now
  explicitly disable retryable writes via the connection string
  (e.g. \ 
``MongoClient("mongodb://my.mongodb.cluster/db?retryWrites=false")``) \ 
or
  the :class:`~pymongo.mongo_client.MongoClient` constructor's keyword argument
  (e.g. ``MongoClient("mongodb://my.mongodb.cluster/db", \ 
retryWrites=False)``)
  to avoid running into :class:`~pymongo.errors.OperationFailure` exceptions
  during write operations. The MMAPv1 storage engine is deprecated and does
  not support retryable writes which are now turned on by default.
- In order to ensure that the ``connectTimeoutMS`` URI option is honored when
  connecting to clusters with a ``mongodb+srv://`` connection string, the
  minimum required version of the optional ``dnspython`` dependency has been
  bumped to 1.16.0. This is a breaking change for applications that use
  PyMongo's SRV support with a version of ``dnspython`` older than 1.16.0.

Changes in Version 3.8.0
------------------------

.. warning:: PyMongo no longer supports Python 2.6. RHEL 6 users should install
  Python 2.7 or newer from `Red Hat Software Collections
  <https://www.softwarecollections.org>`_. CentOS 6 users should install Python
  2.7 or newer from `SCL
  <https://wiki.centos.org/AdditionalResources/Repositories/SCL>`_

.. warning:: PyMongo no longer supports PyPy3 versions older than 3.5. Users
  must upgrade to PyPy3.5+.

- :class:`~bson.objectid.ObjectId` now implements the `ObjectID specification
  version 0.2 \ 
<https://github.com/mongodb/specifications/blob/master/source/objectid.rst>`_.
- For better performance and to better follow the GridFS spec,
  :class:`~gridfs.grid_file.GridOut` now uses a single cursor to read all the
  chunks in the file. Previously, each chunk in the file was queried
  individually using :meth:`~pymongo.collection.Collection.find_one`.
- :meth:`gridfs.grid_file.GridOut.read` now only checks for extra chunks after
  reading the entire file. Previously, this method would check for extra
  chunks on every call.
- :meth:`~pymongo.database.Database.current_op` now always uses the
  ``Database``'s  :attr:`~pymongo.database.Database.codec_options`
  when decoding the command response. Previously the codec_options
  was only used when the MongoDB server version was <= 3.0.
- Undeprecated :meth:`~pymongo.mongo_client.MongoClient.get_default_database`
  and added the ``default`` parameter.
- TLS Renegotiation is now disabled when possible.
- Custom types can now be directly encoded to, and decoded from MongoDB using
  the :class:`~bson.codec_options.TypeCodec` and
  :class:`~bson.codec_options.TypeRegistry` APIs. For more information, see
  the :doc:`custom type example <examples/custom_type>`.
- Attempting a multi-document transaction on a sharded cluster now raises a
  :exc:`~pymongo.errors.ConfigurationError`.
- :meth:`pymongo.cursor.Cursor.distinct` and
  :meth:`pymongo.cursor.Cursor.count` now send the Cursor's
  :meth:`~pymongo.cursor.Cursor.comment` as the "comment" top-level
  command option instead of "$comment". Also, note that \ 
"comment" must be a
  string.
- Add the ``filter`` parameter to
  :meth:`~pymongo.database.Database.list_collection_names`.
- Changes can now be requested from a ``ChangeStream`` cursor without blocking
  indefinitely using the new
  :meth:`pymongo.change_stream.ChangeStream.try_next` method.
- Fixed a reference leak bug when splitting a batched write command based on
  maxWriteBatchSize or the max message size.
- Deprecated running find queries that set :meth:`~pymongo.cursor.Cursor.min`
  and/or :meth:`~pymongo.cursor.Cursor.max` but do not also set a
  :meth:`~pymongo.cursor.Cursor.hint` of which index to use. The find command
  is expected to require a :meth:`~pymongo.cursor.Cursor.hint` when using
  min/max starting in MongoDB 4.2.
- Documented support for the uuidRepresentation URI option, which has been
  supported since PyMongo 2.7. Valid values are `pythonLegacy` (the default),
  `javaLegacy`, `csharpLegacy` and `standard`. New applications should consider
  setting this to `standard` for cross language compatibility.
- :class:`~bson.raw_bson.RawBSONDocument` now validates that the ``bson_bytes``
  passed in represent a single bson document. Earlier versions would mistakenly
  accept multiple bson documents.
- Iterating over a :class:`~bson.raw_bson.RawBSONDocument` now maintains the
  same field order of the underlying raw BSON document.
- Applications can now register a custom server selector. For more information
  see the :doc:`server selector example <examples/server_selection>`.
- The connection pool now implements a LIFO policy.

Unavoidable breaking changes:

- In order to follow the ObjectID Spec version 0.2, an ObjectId's 3-byte
  machine identifier and 2-byte process id have been replaced with a single
  5-byte random value generated per process. This is a breaking change for any
  application that attempts to interpret those bytes.

Log message:
py-mongo: updated to 3.7.2

Version 3.7.2 fixes a few issues discovered since the release of 3.7.1.
- Fixed a bug in retryable writes where a previous command's "txnNumber"
  field could be sent leading to incorrect results.
- Fixed a memory leak of a few bytes on some insert, update, or delete
  commands when running against MongoDB 3.6+.
- Fixed a bug that caused :meth:pymongo.collection.Collection.ensure_index
  to only cache a single index per database.
- Updated the documentation examples to use
  :meth:pymongo.collection.Collection.count_documents instead of
  :meth:pymongo.collection.Collection.count and
  :meth:pymongo.cursor.Cursor.count.

Log message:
py-mongo: updated to 3.7.1

Changes in Version 3.7.1

Version 3.7.1 fixes a few issues discovered since the release of 3.7.0.

Calling :meth:~pymongo.database.Database.authenticate more than once with the \ 
same credentials results in OperationFailure.
Authentication fails when SCRAM-SHA-1 is used to authenticate users with only \ 
MONGODB-CR credentials.
A millisecond rounding problem when decoding datetimes in the pure Python BSON \ 
decoder on 32 bit systems and AWS lambda.
Issues Resolved

Changes in Version 3.7.0

Version 3.7 adds support for MongoDB 4.0. Highlights include:

Support for single replica set multi-document ACID transactions. See \ 
:ref:transactions-ref.
Support for wire protocol compression. See the \ 
:meth:~pymongo.mongo_client.MongoClient documentation for details.
Support for Python 3.7.
New count methods, :meth:~pymongo.collection.Collection.count_documents and \ 
:meth:~pymongo.collection.Collection.estimated_document_count. \ 
:meth:~pymongo.collection.Collection.count_documents is always accurate when \ 
used with MongoDB 3.6+, or when used with older standalone or replica set \ 
deployments. With older sharded clusters is it always accurate when used with \ 
Primary read preference. It can also be used in a transaction, unlike the now \ 
deprecated :meth:pymongo.collection.Collection.count and \ 
:meth:pymongo.cursor.Cursor.count methods.
Support for watching changes on all collections in a database using the new \ 
:meth:pymongo.database.Database.watch method.
Support for watching changes on all collections in all databases using the new \ 
:meth:pymongo.mongo_client.MongoClient.watch method.
Support for watching changes starting at a user provided timestamp using the new \ 
start_at_operation_time parameter for the watch() helpers.
Better support for using PyMongo in a FIPS 140-2 environment. Specifically, the \ 
following features and changes allow PyMongo to function when MD5 support is \ 
disabled in OpenSSL by the FIPS Object Module:
Support for the :ref:SCRAM-SHA-256 <scram_sha_256> authentication \ 
mechanism. The :ref:GSSAPI <gssapi>, :ref:PLAIN <sasl_plain>, and \ 
:ref:MONGODB-X509 <mongodb_x509> mechanisms can also be used to avoid \ 
issues with OpenSSL in FIPS environments.
MD5 checksums are now optional in GridFS. See the disable_md5 option of \ 
:class:~gridfs.GridFS and :class:~gridfs.GridFSBucket.
:class:~bson.objectid.ObjectId machine bytes are now hashed using FNV-1a instead \ 
of MD5.
The :meth:~pymongo.database.Database.list_collection_names and \ 
:meth:~pymongo.database.Database.collection_names methods use the nameOnly \ 
option when supported by MongoDB.
The :meth:pymongo.collection.Collection.watch method now returns an instance of \ 
the :class:~pymongo.change_stream.CollectionChangeStream class which is a \ 
subclass of :class:~pymongo.change_stream.ChangeStream.
SCRAM client and server keys are cached for improved performance, following RFC 5802.
If not specified, the authSource for the :ref:PLAIN <sasl_plain> \ 
authentication mechanism defaults to $external.
wtimeoutMS is once again supported as a URI option.
When using unacknowledged write concern and connected to MongoDB server version \ 
3.6 or greater, the bypass_document_validation option is now supported in the \ 
following write helpers: :meth:~pymongo.collection.Collection.insert_one, \ 
:meth:~pymongo.collection.Collection.replace_one, \ 
:meth:~pymongo.collection.Collection.update_one, \ 
:meth:~pymongo.collection.Collection.update_many.

Deprecations:
Deprecated :meth:pymongo.collection.Collection.count and \ 
:meth:pymongo.cursor.Cursor.count. These two methods use the count command and \ 
may or may not be accurate, depending on the options used and connected MongoDB \ 
topology. Use :meth:~pymongo.collection.Collection.count_documents instead.
Deprecated the snapshot option of :meth:~pymongo.collection.Collection.find and \ 
:meth:~pymongo.collection.Collection.find_one. The option was deprecated in \ 
MongoDB 3.6 and removed in MongoDB 4.0.
Deprecated the max_scan option of :meth:~pymongo.collection.Collection.find and \ 
:meth:~pymongo.collection.Collection.find_one. The option was deprecated in \ 
MongoDB 4.0. Use maxTimeMS instead.
Deprecated :meth:~pymongo.mongo_client.MongoClient.close_cursor. Use \ 
:meth:~pymongo.cursor.Cursor.close instead.
Deprecated :meth:~pymongo.mongo_client.MongoClient.database_names. Use \ 
:meth:~pymongo.mongo_client.MongoClient.list_database_names instead.
Deprecated :meth:~pymongo.database.Database.collection_names. Use \ 
:meth:~pymongo.database.Database.list_collection_names instead.
Deprecated :meth:~pymongo.collection.Collection.parallel_scan. MongoDB 4.2 will \ 
remove the parallelCollectionScan command.

Unavoidable breaking changes:
Commands that fail with server error codes 10107, 13435, 13436, 11600, 11602, \ 
189, 91 (NotMaster, NotMasterNoSlaveOk, NotMasterOrSecondary, \ 
InterruptedAtShutdown, InterruptedDueToReplStateChange, PrimarySteppedDown, \ 
ShutdownInProgress respectively) now always raise \ 
:class:~pymongo.errors.NotMasterError instead of \ 
:class:~pymongo.errors.OperationFailure.
:meth:~pymongo.collection.Collection.parallel_scan no longer uses an implicit \ 
session. Explicit sessions are still supported.
Unacknowledged writes (w=0) with an explicit session parameter now raise a \ 
client side error. Since PyMongo does not wait for a response for an \ 
unacknowledged write, two unacknowledged writes run serially by the client may \ 
be executed simultaneously on the server. However, the server requires a single \ 
session must not be used simultaneously by more than one operation. Therefore \ 
explicit sessions cannot support unacknowledged writes. Unacknowledged writes \ 
without a session parameter are still supported.

Log message:
databases/py-mongo: update to 3.5.1

Changes in Version 3.5.1

Version 3.5.1 fixes bugs reported since the release of 3.5.0:
* Work around socket.getsockopt issue with NetBSD.
* :meth:`pymongo.command_cursor.CommandCursor.close` now closes the cursor \ 
synchronously instead of deferring to a background thread.
* Fix documentation build warnings with Sphinx 1.6.x.
