  • Specify a retrospective soft fork implemented in zcashd v2.1.1-1 that limits the nTime field of a block relative to its median-time-past.
  • Correct the definition of median-time-past for the first PoWMedianBlockSpan blocks in a block chain.
  • Add acknowledgements to Henry de Valence, Deirdre Connolly, Chelsea Komlo, and Zancas Wilcox.
  • Add an acknowledgement to Trail of Bits for their security audit.
  • Change indices in the incremental Merkle tree diagram to be zero-based.
  • Use the term "monomorphism" for an injective homomorphism, in the context of a signature scheme with key monomorphism.
