MongoDB C Driver 1.22.1 Released


No changes since 1.22.0. Version incremented to match the libmongoc version.


Bug fixes:

  • Fix documentation build when using Sphinx 5.0 or newer

  • Update patch release of libmongocrypt to 1.5.2: Fix a potential data
    corruption bug in RewrapManyDataKey when rotating encrypted data encryption
    keys backed by GCP or Azure key services.

    The following conditions will trigger this bug:

    A GCP-backed or Azure-backed data encryption key being rewrapped requires
    fetching an access token for decryption of the data encryption key.

    The result of this bug is that the key material for all data encryption keys
    being rewrapped is replaced by new randomly generated material, destroying
    the original key material.

    To mitigate potential data corruption, upgrade to this version or higher
    before using RewrapManyDataKey to rotate Azure-backed or GCP-backed data
    encryption keys. A backup of the key vault collection should always be taken
    before key rotation.


  • Update to Fedora 37 for RPM builds
  • Dependency build of libmongocrypt re-uses the libbson of the depending
