Where do I find the UserStorageProvider interface?

I have keycloak-core and keycloak-server-spi as dependencies (version 20.0.3) but I cannot find the UserStorageProvider and corresponding factory interface.

What artifact do I need to add as my dependency?

Some of the interfaces have been moved to the legacy packages.

Thanks for the hint. (keycloak-model-legacy seems to contain those interfaces)

Is this new Map Storage API already included in 20.0.3? And where do I find something about it?

I posted you a link to a blog post / release note.
So, it might be useful to investigate also other blog posts to find something about new and worthy features, right?

Thanks. Will do that.
