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] #2190 gaiacli init --gen-txs is now gaiacli init --with-txs to reduce confusion
    • #2040 All commands that utilize a validator's address must now use the new bech32 prefix, cosmosval. A validator's Tendermint signing key and address now use a new bech32 prefix, cosmoscons.

  • 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.
    • [docs] #2001 Update slashing spec for slashing period
    • [x/stake, x/slashing] #1305 - Rename "revoked" to "jailed"
    • [x/stake] [#1676] Revoked and jailed validators put into the unbonding state
    • [x/stake] [#1877] Redelegations/unbonding-delegation from unbonding validator have reduced time
    • [x/stake] #2040 Validator operator type has now changed to sdk.ValAddress
      • A new bech32 prefix has been introduced for Tendermint signing keys and addresses, cosmosconspub and cosmoscons respectively.
    • [x/gov] #2195 Made governance use BFT Time instead of Block Heights for deposit and voting periods.

  • SDK

    • [core] #1807 Switch from use of rational to decimal
    • [types] #1901 Validator interface's GetOwner() renamed to GetOperator()
    • [x/slashing] #2122 - Implement slashing period
    • [types] #2119 Parsed error messages and ABCI log errors to make them more human readable.
    • [simulation] Rename TestAndRunTx to Operation #2153
    • [tools] Removed gocyclo #2211
    • [baseapp] Remove SetTxDecoder in favor of requiring the decoder be set in baseapp initialization. #1441

  • Tendermint

FEATURES

  • Gaia REST API (gaiacli advanced rest-server)

    • [lcd] Endpoints to query staking pool and params
    • [lcd] #2110 Add support for simulate=true requests query argument to endpoints that send txs to run simulations of transactions
    • [lcd] #966 Add support for generate_only=true query argument to generate offline unsigned transactions

  • 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 Setting the --gas flag value to 0 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=0.
    • [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] #966 Add --generate-only flag to build an unsigned transaction and write it to STDOUT.

  • 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
