Thank you for your comment. SCRAM-* was added in master branch (version 8.0.0) and given that it will be releases rather soon we won't port it to stable branch (current version 7.1.x). Version 8.0.0 will effectively became stable

It is possible to add SCRAM-SHA-512(-PLUS) in the same time before the release?

8.0.0 is closed (and rc1 will be released in the coming days). We could plan adding SCRAM-SHA-512(-PLUS) to 8.1.0 version.

The feature is implemented but it requires to be enabled with the following configuration:

authRepository () {
    default () {
        credentialEncoders() {
            'SCRAM-SHA-512' (active: true) {}
        }
        credentialDecoders() {
            'SCRAM-SHA-512' (active: true) {}
        }
    }
}

Andrzej, I think that we could backport it to 8.0.1.

I've added documentation and backported changes.

Thank you!
