  MONGODB-AWS.

Changes in Version 1.3.1
------------------------

1.3.1 is a recommended upgrade for all users of 1.3.0.

- Fix a potential data corruption bug in RewrapManyDataKey
  (ClientEncryption.rewrap_many_data_key) 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.
- Bundle libmongocrypt 1.5.2 in release wheels.
