Q: Are Bitnami’s free images going away?
A: Not entirely. Bitnami will continue to offer a limited subset of free, latest-version images intended for development use. These images will be more hardened and secure, but older versions and many applications will be removed from the free tier and moved to the Bitnami Legacy repository.
