0.5.11
- Add digest function (#65, #66).
- Restore compatibility with openssl < 1.1.0 (#73).
- Improved compatibility with OCaml 5 (#79).
- Fix client_verify_callback for NO_NAKED_POINTERS mode. A user-provided verification function in C remains an out-of-heap pointer for 4.x for compatibility, but is boxed for OCaml 5.x or 4.x when configured with --disable-naked-pointers. (#83)
