BREAKING CHANGES

• Gaia REST API (gaiacli advanced rest-server)

  • [x/stake] Validator.Owner renamed to Validator.Operator

• Gaia CLI (gaiacli)

  • [x/stake] Validator.Owner renamed to Validator.Operator
  • [cli] unsafe_reset_all, show_validator, and show_node_id have been renamed to unsafe-reset-all, show-validator, and show-node-id
  • [cli] #1983 --print-response now defaults to true in commands that create and send a transaction
  • [cli] #1983 you can now pass --pubkey or --address to gaiacli keys show to return a plaintext representation of the key's address or public key for use with other commands
  • [cli] #2061 changed proposalID in governance REST endpoints to proposal-id
  • [cli] #2014 gaiacli advanced no longer exists - to access ibc, rest-server, and validator-set commands use gaiacli ibc, gaiacli rest-server, and gaiacli tendermint, respectively
  • [makefile] get_vendor_deps no longer updates lock file it just updates vendor directory. Use update_vendor_deps to update the lock file. #2152
  • [cli] #2221 All commands that utilize a validator's operator address must now use the new Bech32 prefix, cosmosvaloper.

• Gaia

  • Make the transient store key use a distinct store key. #2013
  • [x/stake] #1901 Validator type's Owner field renamed to Operator; Validator's GetOwner() renamed accordingly to comply with the SDK's Validator interface.

    • cosmosvaladdr / cosmosvalpub => cosmosvaloper / cosmosvaloperpub

FEATURES

• Gaia REST API (gaiacli advanced rest-server)

  • [gaia-lite] Endpoints to query staking pool and params
  • [gaia-lite] #2110 Add support for simulate=true requests query argument to endpoints that send txs to run simulations of transactions
  • [gaia-lite] #966 Add support for generate_only=true query argument to generate offline unsigned transactions
  • [gaia-lite] #1953 Add /sign endpoint to sign transactions generated with generate_only=true.
  • [gaia-lite] #1954 Add /broadcast endpoint to broadcast transactions signed by the /sign endpoint.

• Gaia CLI (gaiacli)

  • [cli] Cmds to query staking pool and params
  • [gov][cli] #2062 added --proposal flag to submit-proposal that allows a JSON file containing a proposal to be passed in
  • #2040 Add --bech to gaiacli keys show and respective REST endpoint to provide desired Bech32 prefix encoding
  • [cli] #2047 #2306 Passing --gas=simulate triggers a simulation of the tx before the actual execution. The gas estimate obtained via the simulation will be used as gas limit in the actual execution.
  • [cli] #2047 The --gas-adjustment flag can be used to adjust the estimate obtained via the simulation triggered by --gas=simulate.
  • [cli] #2110 Add --dry-run flag to perform a simulation of a transaction without broadcasting it. The --gas flag is ignored as gas would be automatically estimated.
  • [cli] #2204 Support generating and broadcasting messages with multiple signatures via command line:
    • #966 Add --generate-only flag to build an unsigned transaction and write it to STDOUT.
    • #1953 New sign command to sign transactions generated with the --generate-only flag.
    • #1954 New broadcast command to broadcast transactions generated offline and signed with the sign command.

• Gaia

  • [cli] #2170 added ability to show the node's address via gaiad tendermint show-address

• SDK

  • [querier] added custom querier functionality, so ABCI query requests can be handled by keepers
  • [simulation] #1924 allow operations to specify future operations
  • [simulation] #1924 Add benchmarking capabilities, with makefile commands "test_sim_gaia_benchmark, test_sim_gaia_profile"

• Tendermint

IMPROVEMENTS

• Gaia

  • [x/stake] #2023 Terminate iteration loop in UpdateBondedValidators and UpdateBondedValidatorsFull when the first revoked validator is encountered and perform a sanity check.
  • [x/auth] Signature verification's gas cost now accounts for pubkey type. #2046
  • [x/stake] [x/slashing] Ensure delegation invariants to jailed validators #1883.

• SDK

  • [tools] Make get_vendor_deps deletes .vendor-new directories, in case scratch files are present.
  • [spec] Added simple piggy bank distribution spec
  • [cli] #1632 Add integration tests to ensure basecoind init && basecoind start sequences run successfully for both democoin and basecoin examples.

  • [store] #1952, #2281 Update IAVL dependency to v0.11.0
  • [simulation] Make timestamps randomized #2153
  • [simulation] Make logs not just pure strings, speeding it up by a large factor at greater block heights #2282
  • [simulation] Add a concept of weighting the operations #2303
  • [simulation] Logs get written to file if large, and also get printed on panics #2285
  • [gaiad] #1992 Add optional flag to gaiad testnet to make config directory of daemon (default gaiad) and cli (default gaiacli) configurable
  • [x/stake] Add stake Queriers for Gaia-lite endpoints. This increases the staking endpoints performance by reusing the staking keeper logic for queries. #2249

• Tendermint
