Thank you for verifying the new runtimes. It sounds great.

As you tested, aws-sdk-go-v2 release 2025-10-31 supports the python3.14 and java25 runtimes, and the SDK update was released in v6.20 of the provider.

By updating the SDK, the new runtimes are automatically supported.

Is there anything else we need to do?

Since the documentation does not explicitly list supported runtimes, it is not necessary to update the documentation.

My colleague is raising a change to update the documentation.
