Hi, Bilge! I think that PHP should then clearly explain what is a BC break and what isn't on a separate php.net page. And even explain what php version constraints are safe for Composer libraries. Some languages have such a document: - https://go.dev/doc/go1compat - https://peps.python.org/pep-0387/ -- Valentin
