• (x/genutil) #5775 Fix ExportGenesis in x/genutil to export default genesis state ([]) instead of null.
• (client) #5618 Fix crash on the client when the verifier is not set.
• (crypto/keys/mintkey) #5823 fix errors handling in UnarmorPubKeyBytes (underlying armoring function's return error was not being checked).
• (x/distribution) #5620 Fix nil pointer deref in distribution tax/rewward validation helpers.

v0.38.1

Improvements

• (modules) #5597 Add amount event attribute to the complete_unbonding and complete_redelegation events that reflect the total balances of the completed unbondings and redelegations respectively.

Bug Fixes

• (types) #5579 The IAVL Store#Commit method has been refactored to delete a flushed version if it is not a snapshot version. The root multi-store now keeps track of commitInfo instead of types.CommitID. During Commit of the root multi-store, lastCommitInfo is updated from the saved state and is only flushed to disk if it is a snapshot version. During Query of the root multi-store, if the request height is the latest height, we'll use the store's lastCommitInfo. Otherwise, we fetch commitInfo from disk.
• (x/bank) #5531 Added missing amount event to MsgMultiSend, emitted for each output.
• (x/gov) #5622 Track any events emitted from a proposal's handler upon successful execution.

v0.37.7

v0.38.0

Release Notes

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.

Features

• (store) #5435 New iterator for paginated requests. Iterator limits DB reads to the range of the requested page.
• (x/evidence) #5240 Initial implementation of the x/evidence module.
• (cli) #5212 The q gov proposals command now supports pagination.
• (store) #4724 Multistore supports substore migrations upon load. New rootmulti.Store.LoadLatestVersionAndUpgrade method in
  Baseapp supports StoreLoader to enable various upgrade strategies. It no
  longer panics if the store to load contains substores that we didn't explicitly mount.
• #4972 A TxResponse with a corresponding code
  and tx hash will be returned for specific Tendermint errors:
  • CodeTxInMempoolCache
  • CodeMempoolIsFull
  • CodeTxTooLarge
• #3872 Implement a RESTful endpoint and cli command to decode transactions.
• (keys) #4754 Introduce new Keybase implementation that can
  leverage operating systems' built-in functionalities to securely store secrets. MacOS users may encounter
  the following issue with the go-keychain library. If
  you encounter this issue, you must upgrade your xcode command line tools to version >= 10.2. You can
  upgrade via: sudo rm -rf /Library/Developer/CommandLineTools; xcode-select --install. Verify the
  correct version via: pkgutil --pkg-info=com.apple.pkg.CLTools_Executables.
• #5355 Client commands accept a new --keyring-backend option through which users can specify which backend should be used
  by the new key store:
  • ...
