  2. Special thanks to external contributors on this release:
  3. @goolAdapter, @bradyjoestar
  4. BREAKING CHANGES:
  5. * CLI/RPC/Config
  6. * [config] \#2232 timeouts as time.Duration, not ints
  7. * [config] \#2505 Remove Mempool.RecheckEmpty (it was effectively useless anyways)
  8. * [config] `mempool.wal` is disabled by default
  9. * [rpc] \#2298 `/abci_query` takes `prove` argument instead of `trusted` and switches the default
  10. behaviour to `prove=false`
  11. * [privval] \#2459 Split `SocketPVMsg`s implementations into Request and Response, where the Response may contain a error message (returned by the remote signer)
  12. * Apps
  13. * [abci] \#2298 ResponseQuery.Proof is now a structured merkle.Proof, not just
  14. arbitrary bytes
  15. * Go API
  16. * [node] Remove node.RunForever
  17. * [config] \#2232 timeouts as time.Duration, not ints
  18. * [rpc/client] \#2298 `ABCIQueryOptions.Trusted` -> `ABCIQueryOptions.Prove`
  19. * [types] \#2298 Remove `Index` and `Total` fields from `TxProof`.
  20. * [crypto/merkle & lite] \#2298 Various changes to accomodate General Merkle trees
  21. * Blockchain Protocol
  22. * [types] \#2459 `Vote`/`Proposal`/`Heartbeat` use amino encoding instead of JSON in `SignBytes`.
  23. * [types] \#2512 Remove the pubkey field from the validator hash
  24. * P2P Protocol
  25. FEATURES:
  26. - [crypto/merkle] \#2298 General Merkle Proof scheme for chaining various types of Merkle trees together
  27. - [abci] \#2557 Add `Codespace` field to `Response{CheckTx, DeliverTx, Query}`
  28. IMPROVEMENTS:
  29. - [consensus] [\#2169](https://github.com/cosmos/cosmos-sdk/issues/2169) add additional metrics
  30. - [p2p] [\#2169](https://github.com/cosmos/cosmos-sdk/issues/2169) add additional metrics
  31. - [config] \#2232 added ValidateBasic method, which performs basic checks
  32. - [tools] \#2238 Binary dependencies are now locked to a specific git commit
  33. - [crypto] \#2099 make crypto random use chacha, and have forward secrecy of generated randomness
  34. BUG FIXES:
