3.0.0 -- 2021-07-01

Deprecation

The AWS Encryption SDK for Python no longer supports Python 2 or Python 3.4
as of major version 3.x; only Python 3.5+ is supported. Customers using Python 2
or Python 3.4 can still use the 2.x line of the AWS Encryption SDK for Python,
which will continue to receive security updates for the next 12 months, in accordance
with our Support Policy.

Maintenance

• Move away from deprecated cryptography int_from_bytes #355.

2.4.0 -- 2021-07-01

Deprecation Announcement

The AWS Encryption SDK for Python is discontinuing support for Python 2. Future major versions of this library will drop support for Python 2 and begin to adopt changes that are known to break Python 2.

Support for Python 3.4 will be removed at the same time. Moving forward, we will support Python 3.5+.

Security updates will still be available for the Encryption SDK 2.x line for the next 12 months, in accordance with our Support Policy.

1.7.0 -- 2020-09-24

Features

• Updates to the AWS Encryption SDK. ef90351

Deprecations

• KMSMasterKeyProvider is deprecated. Customers should move to StrictAwsKmsMasterKeyProvider with explicit key ids, or DiscoveryAwsKmsMasterKeyProvider to allow decryption of any ciphertext to which the application has access.
• The encrypt, decrypt, and stream methods in the aws_encryption_sdk module are deprecated. Customers should move to the identically named methods on the new EncryptionSDKClient class.
