+- dst for mapToG1 has changed to `BLS_SIG_BLS12381G1_XMD:SHA-256_SSWU_RO_POP_`.
 - `mclBn_eth*` functions are removed.
 - `mcl::bn::mapToG1(G1& out, const Fp& v)` supports `BLS12_MAP_FP_TO_G1` in [EIP 2537](https://eips.ethereum.org/EIPS/eip-2537).
 - `mcl::bn::hashAndMapToG1(G1& out, const void *msg, size_t msgSize)` supports ([hash-to-curve-09 BLS12381G1_XMD:SHA-256_SSWU_RO_](https://www.ietf.org/id/draft-irtf-cfrg-hash-to-curve-09.html#name-bls12381g1_xmdsha-256_sswu_))
