  • Add mongoc_client_encryption_create_encrypted_collection to automatically create data encryption keys when creating a new encrypted collection.
• Support new security features.
  • Add ability to fetch KMS credentials automatically from Azure, GCP, and AWS environments.
  • Support authentication with KMS AWS temporary credentials.
  • Cache fetched AWS credentials.
  • Support AWS IAM Roles for service accounts, EKS in particular.

Build Configuration:

• The ENABLE_BSON configure-time option has been removed. Build scripts that
  used ENABLE_BSON=SYSTEM should be updated to use USE_SYSTEM_LIBBSON=TRUE.
  If the build script needs to support building arbitrary versions of the C
  driver, add both ENABLE_BSON=SYSTEM and USE_SYSTEM_LIBBSON=TRUE.
