Changes in Version 4.16.0 (2026/01/07)

PyMongo 4.16 brings a number of changes including:

  • Removed invalid documents from :class:bson.errors.InvalidDocument error messages as doing so may leak sensitive user data. Instead, invalid documents are stored in :attr:bson.errors.InvalidDocument.document.
  • PyMongo now requires dnspython>=2.6.1, since dnspython 1.0 is no longer maintained. The minimum version is 2.6.1 to account for CVE-2023-29483 <https://www.cve.org/CVERecord?id=CVE-2023-29483>_.
  • Removed support for Eventlet. Eventlet is actively being sunset by its maintainers and has compatibility issues with PyMongo's dnspython dependency.
  • Use Zstandard support from the standard library for Python 3.14+, and use backports.zstd for older versions.
  • Fixed return type annotation for find_one_and_* methods on :class:~pymongo.asynchronous.collection.AsyncCollection and :class:~pymongo.synchronous.collection.Collection to include None.
  • Added support for NumPy 1D-arrays in :class:bson.binary.BinaryVector.
  • Prevented :class:~pymongo.encryption.ClientEncryption from loading the crypt shared library to fix "MongoCryptError: An existing crypt_shared library is loaded by the application" unless the linked library search path is set.
