Changes in Version 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

See the PyMongo 4.8 release notes in JIRA for the list of resolved issues in this release.
