v0.33

This release contains breaking changes to the Block#Header, specifically NumTxs and TotalTxs were removed (#2521). Here's how this change affects different modules:

  • apps: it breaks the ABCI header field numbering
  • state: it breaks the format of State on disk
  • RPC: all RPC requests which expose the header broke
  • Go API: the Header broke
  • P2P: since blocks go over the wire, technically the P2P protocol broke

v0.32.13

Cosmos SDK Changelog

v0.41.0 - From release notes

Support Amino JSON for IBC MsgTransfer This change breaks state backward compatibility.

At the moment hardware wallets are unable to sign messages using SIGN_MODE_DIRECT because the cosmos ledger app does not support proto encoding andSIGN_MODE_TEXTUAL is not available yet.

In order to enable hardware wallets users to interact with IBC, amino JSON support was added to MsgTransfer only.

Counterparty.ChannelID not available in OnChanOpenAck callback implementation. This change breaks state backward compatibility.

In a previous version the Counterparty.ChannelID was available for an OnChanOpenAck callback implementation (read via channelKeeper.GetChannel(). Due to a regression, the channelID is currently empty.

The issue has been fixed by reordering IBC ChanOpenAck and ChanOpenConfirm to execute the core handlers logic first, followed by application callbacks.

It breaks state backward compatibility because the current change consumes more gas, which means that in an updated node a TX might fail because it ran out of gas whilst in older versions it would be successful.

v0.40.0 - 2021-01-08

v0.40.0, known as the Stargate release of the Cosmos SDK, is one of the largest releases of the Cosmos SDK since launch. Please read through this changelog and release notes to make sure you are aware of any relevant breaking changes.

Client Breaking Changes

  • CLI
    • (client/keys) #5889 remove keys update command.
    • (x/auth) #5844 tx sign command now returns an error when signing is attempted with offline/multisig keys.
    • (x/auth) #6108 tx sign command's --validate-signatures flag is migrated into a tx validate-signatures standalone command.
    • (x/auth) #7788 Remove tx auth subcommands, all auth subcommands exist as tx <subcommand>
    • (x/genutil) #6651 The gentx command has been improved. No longer are --from and --name flags required. Instead, a single argument, name, is required which refers to the key pair in the Keyring. In addition, an optional --moniker flag can be provided to override the moniker found in config.toml.
    • (x/upgrade) #7697 Rename flag name "--time" to "--upgrade-time", "--info" to "--upgrade-info", to keep it consistent with help message.
  • REST / Queriers
    • (api) #6426 The ability to start an out-of-process API REST server has now been removed. Instead, the API server is now started in-process along with the application and Tendermint. Configuration options have been added to app.toml to enable/disable the API server along with additional HTTP server options.
    • (client) #7246 The rest server endpoint /swagger-ui/ is replaced by /swagger/, and contains swagger documentation for gRPC Gateway routes in addition to legacy REST routes. Swagger API is exposed only if set in app.toml.
    • (x/auth) #5702 The x/auth querier route has changed from "acc" to "auth".
    • (x/bank) #5572 The /bank/balances/{address} endpoint now returns all account balances or a single balance by denom when the denom query parameter is present.
    • (x/evidence) #5952 Remove CLI and REST handlers for querying x/evidence parameters.
    • (x/gov) #6295 Fix typo in querying governance params.
  • General
    • (baseapp) #6384 The Result.Data is now a Protocol Buffer encoded binary blob of type TxData. The TxData contains Data which contains a list of Protocol Buffer encoded message data and the corresponding message type.
    • (client) #5783 Unify all coins representations on JSON client requests for governance proposals.
    • (crypto) #7419 The SDK doesn't use Tendermint's crypto.PubKey interface anymore, and uses instead it's own PubKey interface, defined in crypto/types. Replace all instances of crypto.PubKey by cryptotypes.Pubkey.
    • (store/rootmulti) #6390 Proofs of empty stores are no longer supported.
    • (store/types) #5730 store.types.Cp() is removed in favour of types.CopyBytes().
    • (x/auth) #6054 Remove custom JSON marshaling for base accounts as multsigs cannot be bech32 decoded.
    • (x/auth/vesting) #6859 Custom JSON marshaling of vesting accounts was removed. Vesting accounts are now marshaled using their default proto or amino JSON representation.
    • (x/bank) #5785 In x/bank errors, JSON strings coerced to valid UTF-8 bytes at JSON marshalling time are now replaced by human-readable expressions. This change can potentially break compatibility with all those client side tools that parse log messages.
    • (x/evidence) #7538 The ABCI's Result.Data field for MsgSubmitEvidence responses does not contain the raw evidence's hash, but the protobuf encoded MsgSubmitEvidenceResponse struct.
    • (x/gov) #7533 The ABCI's Result.Data field for MsgSubmitProposal responses does not contain a raw binary encoding of the proposalID, but the protobuf encoded MsgSubmitSubmitProposalResponse struct.
    • (x/gov) #6859 ProposalStatus and VoteOption are now JSON serialized using its protobuf name, so expect names like PROPOSAL_STATUS_DEPOSIT_PERIOD as opposed to DepositPeriod.
    • (x/staking) #7499 BondStatus is now a protobuf enum instead of an int32, and JSON serialized using its protobuf name, so expect names like BOND_STATUS_UNBONDING as opposed to Unbonding.
    • (x/staking) #7556 The ABCI's Result.Data field for MsgBeginRedelegate and MsgUndelegate responses does not contain custom binary marshaled completionTime, but the protobuf encoded MsgBeginRedelegateResponse and MsgUndelegateResponse structs respectively

API Breaking Changes

  • Baseapp / Client
    • (AppModule) #7518 #7584 Rename AppModule.RegisterQueryServices to AppModule.RegisterServices, as this method now registers multiple services (the gRPC query service and the protobuf Msg service). A Configurator struct is used to hold the different services.
    • (baseapp) #5865 The SimulationResponse returned from tx simulation is now JSON encoded instead of Amino binary.
    • (client) #6290 CLIContext is renamed to Context. Context and all related methods have been moved from package context to client.
    • (client) #6525 Removed support for indent in JSON responses. Clients should consider piping to an external tool such as jq.
    • (client) #8107 Renamed PrintOutput and PrintOutputLegacy methods of the context.Client object to PrintProto and PrintObjectLegacy.
    • (client/flags) #6632 Remove NewCompletionCmd(), the function is now available in tendermint.
    • (client/input) #5904 Removal of unnecessary GetCheckPassword, PrintPrefixed functions.
    • (client/keys) #5889 Rename NewKeyBaseFromDir() -> NewLegacyKeyBaseFromDir().
    • (client/keys) #5820 Removed method CloseDB from Keybase interface.
    • (client/rpc) #6290 client package and subdirs reorganization.
    • (client/lcd) #6290 CliCtx of struct RestServer in package client/lcd has been renamed to ClientCtx.
    • (codec) #6330 codec.RegisterCrypto has been moved to the crypto/codec package and the global codec.Cdc Amino instance has been deprecated and moved to the codec/legacy_global package.
    • (codec) #8080 Updated the codec.Marshaler interface
      • Moved MarshalAny and UnmarshalAny helper functions to codec.Marshaler and renamed to MarshalInterface and UnmarshalInterface respectively. These functions must take interface as a parameter (not a concrete type nor Any object). Underneath they use Any wrapping for correct protobuf serialization.
    • (crypto) #6780 Move ledger code to its own package.
    • (crypto/types/multisig) #6373 multisig.Multisignature has been renamed to AminoMultisignature
    • (codec) *codec.LegacyAmino is now a wrapper around Amino which provides backwards compatibility with protobuf Any. ALL legacy code should use *codec.LegacyAmino instead of *amino.Codec directly
    • (crypto) #5880 Merge crypto/keys/mintkey into crypto.
    • (crypto/hd) #5904 crypto/keys/hd moved to crypto/hd.
    • (crypto/keyring):
      • #5866 Rename crypto/keys/ to crypto/keyring/.
      • #5904 Keybase -> Keyring interfaces migration. LegacyKeybase interface is added in order to guarantee limited backward compatibility with the old Keybase interface for the sole purpose of migrating keys across the new keyring backends. NewLegacy constructor is provided #5889 to allow for smooth migration of keys from the legacy LevelDB based implementation to new keyring backends. Plus, the package and the new keyring no longer depends on the sdk.Config singleton. Please consult the package documentation for more information on how to implement the new Keyring interface.
      • #5858 Make Keyring store keys by name and address's hexbytes representation.
    • (export) #5952 AppExporter now returns ABCI consensus parameters to be included in marshaled exported state. These parameters must be returned from the application via the BaseApp.
    • (simapp) Deprecating and renaming MakeEncodingConfig to MakeTestEncodingConfig (both in simapp and simapp/params packages).
    • (store) #5803 The store.CommitMultiStore interface now includes the new snapshots.Snapshotter interface as well.
    • (types) #5579 The keepRecent field has been removed from the PruningOptions type. The PruningOptions type now only includes fields KeepEvery and SnapshotEvery, where KeepEvery determines which committed heights are flushed to disk and SnapshotEvery determines which of these heights are kept after pruning. The IsValid method should be called whenever using these options. Methods SnapshotVersion and FlushVersion accept a version arugment and determine if the version should be flushed to disk or kept as a snapshot. Note, KeepRecent is automatically inferred from the options and provided directly the IAVL store.
    • (types) #5533 Refactored AppModuleBasic and AppModuleGenesis to now accept a codec.JSONMarshaler for modular serialization of genesis state.
    • (types/rest) #5779 Drop unused Parse{Int64OrReturnBadRequest,QueryParamBool}() functions.

v0.39.1 - 2020-08-11

Client Breaking

  • (x/auth) #6861 Remove public key Bech32 encoding for all account types for JSON serialization, instead relying on direct Amino encoding. In addition, JSON serialization utilizes Amino instead of the Go stdlib, so integers are treated as strings.

v0.39.0 - 2020-07-20

API Breaking Changes

  • (baseapp) #5837 Transaction simulation now returns a SimulationResponse which contains the GasInfo and Result from the execution.

Client Breaking Changes

  • (x/auth) #6745 Remove BaseAccount's custom JSON {,un}marshalling.

State Machine Breaking

  • (genesis) #5506 The x/distribution genesis state now includes params instead of individual parameters.
  • (genesis) #5017 The x/genaccounts module has been deprecated and all components removed except the legacy/ package. This requires changes to the genesis state. Namely, accounts now exist under app_state.auth.accounts. The corresponding migration logic has been implemented for v0.38 target version. Applications can migrate via: $ {appd} migrate v0.38 genesis.json.
  • (modules) #5299 Handling of ABCIEvidenceTypeDuplicateVote during BeginBlock along with the corresponding parameters (MaxEvidenceAge) have moved from the x/slashing module to the x/evidence module.

API Breaking Changes

  • (modules) #5506 Remove individual setters of x/distribution parameters. Instead, follow the module spec in getting parameters, setting new value(s) and finally calling SetParams.
  • (types) #5495 Remove redundant (Must)Bech32ify* and (Must)Get*KeyBech32 functions in favor of (Must)Bech32ifyPubKey and (Must)GetPubKeyFromBech32 respectively, both of which take a Bech32PubKeyType (string).
  • (types) #5430 DecCoins#Add parameter changed from DecCoins to ...DecCoin, Coins#Add parameter changed from Coins to ...Coin.
  • (baseapp/types) #5421 The Error interface (types/errors.go) has been removed in favor of the concrete type defined in types/errors/ which implements the standard error interface.
    • As a result, the Handler and Querier implementations now return a standard error. Within BaseApp, runTx now returns a (GasInfo, *Result, error) tuple and runMsgs returns a (*Result, error) tuple. A reference to a Result is now used to indicate success whereas an error signals an invalid message or failed message execution. As a result, the fields Code, Codespace, GasWanted, and GasUsed have been removed the Result type. The latter two fields are now found in the GasInfo type which is always returned regardless of execution outcome.
    • Note to developers: Since all handlers and queriers must now return a standard error, the types/errors/ package contains all the relevant and pre-registered errors that you typically work with. A typical error returned will look like sdkerrors.Wrap(sdkerrors.ErrUnknownRequest, "..."). You can retrieve relevant ABCI information from the error via ABCIInfo.
  • (client) #5442 Remove client/alias.go as it's not necessary and components can be imported directly from the packages.
  • (store) #4748 The CommitMultiStore interface now requires a SetInterBlockCache method. Applications that do not wish to support this can simply have this method perform a no-op.
  • (modules) #4665 Refactored x/gov module structure and dev-UX:
    • Prepare for module spec integration
    • Update gov keys to use big endian encoding instead of little endian
  • (modules) #5017 The x/genaccounts module has been deprecated and all components removed except the legacy/ package.
  • #4486 Vesting account types decoupled from the x/auth module and now live under x/auth/vesting. Applications wishing to use vesting account types must be sure to register types via RegisterCodec under the new vesting package.
  • #4486 The NewBaseVestingAccount constructor returns an error if the provided arguments are invalid.
  • (x/auth) #5006 Modular AnteHandler via composable decorators:
    • The AnteHandler interface now returns (newCtx Context, err error) instead of (newCtx Context, result sdk.Result, abort bool)
    • The NewAnteHandler function returns an AnteHandler function that returns the new AnteHandler interface and has been moved into the auth/ante directory.
    • ValidateSigCount, ValidateMemo, ProcessPubKey, EnsureSufficientMempoolFee, and GetSignBytes have all been removed as public functions.
    • Invalid Signatures may return InvalidPubKey instead of Unauthorized error, since the transaction will first hit SetPubKeyDecorator before the SigVerificationDecorator runs.
    • StdTx#GetSignatures will return an array of just signature byte slices [][]byte instead of returning an array of StdSignature structs. To replicate the old behavior, use the public field StdTx.Signatures to get back the array of StdSignatures []StdSignature.
  • (modules) #5299 HandleDoubleSign along with params MaxEvidenceAge and DoubleSignJailEndTime have moved from the x/slashing module to the x/evidence module.
  • (keys) #4941 Keybase concrete types constructors such as NewKeyBaseFromDir and NewInMemory now accept optional parameters of type KeybaseOption. These optional parameters are also added on the keys sub-commands functions, which are now public, and allows these options to be set on the commands or ignored to default to previous behavior.
  • #5547 NewKeyBaseFromHomeFlag constructor has been removed.
  • #5439 Further modularization was done to the keybase package to make it more suitable for use with different key formats and algorithms:
    • The WithKeygenFunc function added as a KeybaseOption which allows a custom bytes to key implementation to be defined when keys are created.
    • The WithDeriveFunc function added as a KeybaseOption allows custom logic for deriving a key from a mnemonic, bip39 password, and HD Path.
    • BIP44 is no longer build into keybase.CreateAccount(). It is however the default when using the client/keys add command.
    • SupportedAlgos and SupportedAlgosLedger functions return a slice of SigningAlgos that are supported by the keybase and the ledger integration respectively.
  • (simapp) #5419 The helpers.GenTx() now accepts a gas argument.
  • (baseapp) #5455 A sdk.Context is now passed into the router.Route() function.

Client Breaking Changes

  • (rest) #5270 All account types now implement custom JSON serialization.
  • (rest) #4783 The balance field in the DelegationResponse type is now sdk.Coin instead of sdk.Int
  • (x/auth) #5006 The gas required to pass the AnteHandler has increased significantly due to modular AnteHandler support. Increase GasLimit accordingly.
  • (rest) #5336 MsgEditValidator uses description instead of Description as a JSON key.
  • (keys) #5097 Due to the keybase -> keyring transition, keys need to be migrated. See keys migrate command for more info.
  • (x/auth) #5424 Drop decode-tx command from x/auth/client/cli, duplicate of the decode command.
