OpenSSL 4.0.0 was released in April 2026, and a shared-docker builder image (`shared-docker-ci-standard-builder-with-openssl-4.0.0`) is now available. The builder configures OpenSSL with `--api=3.0.0`, preserving the 3.0 application API — so extending every `openssl_3.0.x` compile guard to also list `openssl_4.0.x` is sufficient to support the new backend at the FFI boundary. Also drops "supported on..." docstrings that listed every supported backend — tautological prose that's better omitted. Version qualifiers remain where they express a real subset (SHAKE variable-length output). Incidentally corrects a pre-existing docstring in `ssl/crypto/crypto.pony` that listed PBKDF2 as requiring OpenSSL only, though LibreSSL has been supported since first-class LibreSSL landed. Closes #44
