We are pleased to announce the 4.8.0 release of PyMongo - MongoDB’s Python Driver.

Changes in 4.8.0

PyMongo 4.8 brings a number of improvements including:

  • The handshake metadata for “os.name” on Windows has been simplified to “Windows” to improve import time.

  • The repr of bson.binary.Binary is now redacted when the subtype is SENSITIVE_SUBTYPE(8).

  • Secure Software Development Life Cycle automation for release process. GitHub Releases now include a Software Bill of Materials, and signature files corresponding to the distribution files released on PyPI.

  • Fixed a bug in change streams where both startAtOperationTime and resumeToken could be added to a retry attempt, which caused the retry to fail.

  • Fallback to stdlib ssl module when pyopenssl import fails with AttributeError.

  • Improved performance of MongoClient operations, especially when many operations are being run concurrently.

Unavoidable breaking changes

  • Since we are now using hatch as our build backend, we no longer have a usable setup.py file and require installation using pip. Attempts to invoke the setup.py file will raise an exception.
    Additionally, pip >= 21.3 is now required for editable installs.

Issues Resolved
