@item First class support for PyPy
@item Elliptic curves cryptography (NIST P-256 curve only)
@item Better and more compact API (nonce and iv attributes for ciphers,
automatic generation of random nonces and IVs, simplified CTR cipher mode, and
more)
@item SHA-3 (including SHAKE XOFs) and BLAKE2 hash algorithms
@item Salsa20 and ChaCha20 stream ciphers
@item scrypt and HKDF
@item Deterministic (EC)DSA
@item Password-protected PKCS#8 key containers
@item Shamir’s Secret Sharing scheme
@item Random numbers get sourced directly from the OS (and not from a CSPRNG
in userspace)
@item Cleaner RSA and DSA key generation (largely based on FIPS 186-4)
@item Major clean ups and simplification of the code base
