PyMongo 4.0.1 Released

We are pleased to announce the 4.0.1 release of PyMongo - MongoDB’s Python Driver. This release fixes a number of bugs:

  • Fixed a bug that prevented bson.json_util.loads() from decoding a document with a non-string “$regex” field (PYTHON-3028).
  • Fixed a bug where a client may select a hidden/ghost or not yet initialized replica set member leading to unexpected “connection pool paused” errors (PYTHON-3027).

See the changelog for a high-level summary of what is in this release or see the PyMongo 4.0.1 release notes in JIRA for the complete list of resolved issues.

Thank you to everyone who contributed to this release!
