To better accommodate a wide range of HSMs(esp the ledger nano s), Tendermint v0.29.0 is planning to switch to prehashing consensus messages before voting so. ed25519sign(privkey, sha512(msg)), and ed25519verify(pubkey,sha512(msg)) .

I'll link the issue/ PR but we would like to do a coordinated release.
