Changelog
*********

4.0.0 -- 2024-10-29
===================

Features
--------
* Add support for constructs from the `AWS Cryptographic Material Providers Library (MPL) <https://github.com/aws/aws-cryptographic-material-providers-library>`_.
The MPL contains new constructs for encrypting and decrypting your data.
We highly recommend installing the MPL. See `Installing <https://github.com/aws/aws-encryption-sdk-python/tree/master?tab=readme-ov-file#installation>`_ for instructions.

Breaking Changes
^^^^^^^^^^^^^^^^
* The MPL introduces the Required Encryption Context Cryptographic Materials Manager
("required EC CMM") as a new construct for protecting your data.
On encrypt, the required EC CMM will use specific configured
encryption context key-value pairs to calculate the message signature,
but will not store those pairs in the ESDK message.
On decrypt, decryptors must supply these same pairs that were used when encrypting the message.
All messages that have been encrypted with versions of the ESDK <4.0.0 are forward compatible with this change.
However, messages that are constructed with the required EC CMM are not backward compatible with ESDK <4.0.0,
as no version of ESDK <4.0.0 supports reading messages encrypted with the required EC CMM.
A message that is encrypted with the required EC CMM from the MPL must be decrypted with a CMM from the MPL.

Fixes
-----------
* fix: MKPs attempt to decrypt with remaining keys if a preceding raw RSA key failed to decrypt
`#707 <https://github.com/aws/aws-encryption-sdk-python/pull/707>`_
