AWS KMS introduced the ability to display the timestamp and type of the most recent cryptographic operation performed with each key, accessible via the management console or API. This improvement eliminated the need to manually analyze logs to determine key usage.

In addition to visibility, a new condition key was made available to enforce policies protecting keys that had been recently used, helping prevent accidental deletion. This feature was deployed broadly across all commercial, GovCloud, and China AWS regions, enhancing compliance and security monitoring capabilities.
