CHANGELOG.md

<!--
Guiding Principles:

Changelogs are for humans, not machines.
There should be an entry for every single version.
The same types of changes should be grouped.
Versions and sections should be linkable.
The latest version comes first.
The release date of each version is displayed.
Mention whether you follow Semantic Versioning.

Usage:

Change log entries are to be added to the Unreleased section under the
appropriate stanza (see below). Each entry is required to include a tag and
the Github issue reference in the following format:

* (<tag>) \#<issue-number> message

The tag should consist of where the change is being made ex. (x/staking), (store)
The issue numbers will later be link-ified during the release process so you do
not have to worry about including a link manually, but you can if you wish.

Types of changes (Stanzas):

"Features" for new features.
"Improvements" for changes in existing functionality.
"Deprecated" for soon-to-be removed features.
"Bug Fixes" for any bug fixes.
"Client Breaking" for breaking Protobuf, gRPC and REST routes used by end-users.
"CLI Breaking" for breaking CLI commands.
"API Breaking" for breaking exported APIs used by developers building on SDK.
"State Machine Breaking" for any changes that result in a different AppState given same genesisState and txList.

    * `api.Server#Start` now accepts a `context.Context`. The caller is responsible for ensuring that the context is canceled such that the API server can gracefully exit. The caller does not need to stop the server.
    * To start the gRPC server you must first create the server via `NewGRPCServer`, after which you can start the gRPC server via `StartGRPCServer` which accepts a `context.Context`. The caller is responsible for ensuring that the context is canceled such that the gRPC server can gracefully exit. The caller does not need to stop the server.
    * Rename `WaitForQuitSignals` to `ListenForQuitSignals`. Note, this function is no longer blocking. Thus the caller is expected to provide a `context.CancelFunc` which indicates that when a signal is caught, that any spawned processes can gracefully exit.

* (crypto/keyring) [#13734](https://github.com/cosmos/cosmos-sdk/pull/13834) The keyring's `Sign` method now takes a new `signMode` argument. It is only used if the signing key is a Ledger hardware device. You can set it to 0 in all other cases.
* (snapshots) [14048](https://github.com/cosmos/cosmos-sdk/pull/14048) Move the Snapshot package to the store package. This is done in an effort group all storage related logic under one package.

### CLI Breaking Changes

* (all) The migration of modules to [AutoCLI](https://docs.cosmos.network/main/core/autocli) led to no changes in UX but a [small change in CLI outputs](https://github.com/cosmos/cosmos-sdk/issues/16651) where results can be nested.
* (all) Query pagination flags have been renamed with the migration to AutoCLI:
    * `--reverse` -> `--page-reverse`
    * `--offset` -> `--page-offset`
    * `--limit` -> `--page-limit`
    * `--count-total` -> `--page-count-total`
* (cli) [#17184](https://github.com/cosmos/cosmos-sdk/pull/17184) All json keys returned by the `status` command are now snake case instead of pascal case.
* (server) [#17177](https://github.com/cosmos/cosmos-sdk/pull/17177) Remove `iavl-lazy-loading` configuration.
* (x/gov) [#16987](https://github.com/cosmos/cosmos-sdk/pull/16987) In `<appd> query gov proposals` the proposal status flag have renamed from `--status` to `--proposal-status`. Additonally, that flags now uses the ENUM values: `PROPOSAL_STATUS_DEPOSIT_PERIOD`, `PROPOSAL_STATUS_VOTING_PERIOD`, `PROPOSAL_STATUS_PASSED`, `PROPOSAL_STATUS_REJECTED`, `PROPOSAL_STATUS_FAILED`.
* (x/bank) [#16899](https://github.com/cosmos/cosmos-sdk/pull/16899) With the migration to AutoCLI some bank commands have been split in two: 
    * Use `total-supply` (or `total`) for querying the total supply and `total-supply-of` for querying the supply of a specific denom. 
    * Use `denoms-metadata` for querying all denom metadata and `denom-metadata` for querying a specific denom metadata.
* (rosetta) [#16276](https://github.com/cosmos/cosmos-sdk/issues/16276) Rosetta migration to standalone repo.
* (cli) [#15826](https://github.com/cosmos/cosmos-sdk/pull/15826) Remove `<appd> q account` command. Use `<appd> q auth account` instead.

### API Breaking Changes

* (x/auth/ante) [#11985](https://github.com/cosmos/cosmos-sdk/pull/11985) The `MempoolFeeDecorator` has been removed. Instead, the `DeductFeeDecorator` takes a new argument of type `TxFeeChecker`, to define custom fee models. If `nil` is passed to this `TxFeeChecker` argument, then it will default to `checkTxFeeWithValidatorMinGasPrices`, which is the exact same behavior as the old `MempoolFeeDecorator` (i.e. checking fees against validator's own min gas price).
* (x/auth/ante) [#11985](https://github.com/cosmos/cosmos-sdk/pull/11985) The `ExtensionOptionsDecorator` takes an argument of type `ExtensionOptionChecker`. For backwards-compatibility, you can pass `nil`, which defaults to the old behavior of rejecting all tx extensions.
* (crypto/keyring) [#11932](https://github.com/cosmos/cosmos-sdk/pull/11932) Remove `Unsafe*` interfaces from keyring package. Please use interface casting if you wish to access those unsafe functions.

Aliases are kept in the SDK's root `types` package, however, it is encouraged to utilize the new `math` module. As a result, the `Int#ToDec` API has been removed.
* (grpc) [#11642](https://github.com/cosmos/cosmos-sdk/pull/11642) The `RegisterTendermintService` method in the `tmservice` package now requires a `abciQueryFn` query function parameter.

    * Return:
    _`keyring.Record, error` in `SaveOfflineKey`, `SaveLedgerKey`, `SaveMultiSig`, `Key` and `KeyByAddress`.
    _`keyring.Record` instead of `Info` in `NewMnemonic` and `List`.
    * Remove `algo` argument from :
        * `SaveOfflineKey`
    * Take `keyring.Record` instead of `Info` as first argument in:
        * `MkConsKeyOutput`
        * `MkValKeyOutput`
        * `MkAccKeyOutput`

* [#8849](https://github.com/cosmos/cosmos-sdk/pull/8849) Upgrade module no longer supports time based upgrades.
* [#7477](https://github.com/cosmos/cosmos-sdk/pull/7477) Changed Bech32 Public Key serialization in the client facing functionality (CLI, MsgServer, QueryServer):
    * updated the keyring display structure (it uses protobuf JSON serialization) - the output is more verbose.
    * Renamed `MarshalAny` and `UnmarshalAny` to `MarshalInterface` and `UnmarshalInterface` respectively. These functions must take an interface as parameter (not a concrete type nor `Any` object). Underneath they use `Any` wrapping for correct protobuf serialization.

    * `ValidatorI` interface update: `GetConsPubKey` renamed to `TmConsPubKey` (this is to clarify the return type: consensus public key must be a tendermint key); `TmConsPubKey`, `GetConsAddr` methods return error.
    * `Validator` updated according to the `ValidatorI` changes described above.
    * `ToTmValidator` function: added `error` to return values.
    * `Validator.ConsensusPubkey` type changed from `string` to `codectypes.Any`.

* [#9401](https://github.com/cosmos/cosmos-sdk/pull/9401) Fixes incorrect export of IBC identifier sequences. Previously, the next identifier sequence for clients/connections/channels was not set during genesis export. This resulted in the next identifiers being generated on the new chain to reuse old identifiers (the sequences began again from 0).
* [#9408](https://github.com/cosmos/cosmos-sdk/pull/9408) Update simapp to use correct default broadcast mode.
* [#9513](https://github.com/cosmos/cosmos-sdk/pull/9513) Fixes testnet CLI command. Testnet now updates the supply in genesis. Previously, when using add-genesis-account and testnet together, inconsistent genesis files would be produced, as only add-genesis-account was updating the supply.

## [v0.40.0](https://github.com/cosmos/cosmos-sdk/releases/tag/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](https://github.com/cosmos/cosmos-sdk/blob/v0.40.0/RELEASE_NOTES.md) to make
sure you are aware of any relevant breaking changes.

### Client Breaking Changes

* **CLI**
    * (client/keys) [#5889](https://github.com/cosmos/cosmos-sdk/pull/5889) remove `keys update` command.
    * (x/auth) [#5844](https://github.com/cosmos/cosmos-sdk/pull/5844) `tx sign` command now returns an error when signing is attempted with offline/multisig keys.
    * (x/auth) [#6108](https://github.com/cosmos/cosmos-sdk/pull/6108) `tx sign` command's `--validate-signatures` flag is migrated into a `tx validate-signatures` standalone command.
    * (x/auth) [#7788](https://github.com/cosmos/cosmos-sdk/pull/7788) Remove `tx auth` subcommands, all auth subcommands exist as `tx <subcommand>`
    * (x/genutil) [#6651](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/7697) Rename flag name "--time" to "--upgrade-time", "--info" to "--upgrade-info", to keep it consistent with help message.
* **REST / Queriers**
    * (api) [#6426](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/5702) The `x/auth` querier route has changed from `"acc"` to `"auth"`.
    * (x/bank) [#5572](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/5952) Remove CLI and REST handlers for querying `x/evidence` parameters.
    * (x/gov) [#6295](https://github.com/cosmos/cosmos-sdk/pull/6295) Fix typo in querying governance params.
* **General**
    * (baseapp) [#6384](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/issues/5783) Unify all coins representations on JSON client requests for governance proposals.
    * (crypto) [#7419](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/6390) Proofs of empty stores are no longer supported.
    * (store/types) [#5730](https://github.com/cosmos/cosmos-sdk/pull/5730) store.types.Cp() is removed in favour of types.CopyBytes().
    * (x/auth) [#6054](https://github.com/cosmos/cosmos-sdk/pull/6054) Remove custom JSON marshaling for base accounts as multsigs cannot be bech32 decoded.
    * (x/auth/vesting) [#6859](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/issues/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](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/7518) [#7584](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/5865) The `SimulationResponse` returned from tx simulation is now JSON encoded instead of Amino binary.
    * (client) [#6290](https://github.com/cosmos/cosmos-sdk/pull/6290) `CLIContext` is renamed to `Context`. `Context` and all related methods have been moved from package context to client.
    * (client) [#6525](https://github.com/cosmos/cosmos-sdk/pull/6525) Removed support for `indent` in JSON responses. Clients should consider piping to an external tool such as `jq`.
    * (client) [#8107](https://github.com/cosmos/cosmos-sdk/pull/8107) Renamed `PrintOutput` and `PrintOutputLegacy`
    methods of the `context.Client` object to `PrintProto` and `PrintObjectLegacy`.
    * (client/flags) [#6632](https://github.com/cosmos/cosmos-sdk/pull/6632) Remove NewCompletionCmd(), the function is now available in tendermint.
    * (client/input) [#5904](https://github.com/cosmos/cosmos-sdk/pull/5904) Removal of unnecessary `GetCheckPassword`, `PrintPrefixed` functions.
    * (client/keys) [#5889](https://github.com/cosmos/cosmos-sdk/pull/5889) Rename `NewKeyBaseFromDir()` -> `NewLegacyKeyBaseFromDir()`.
    * (client/keys) [#5820](https://github.com/cosmos/cosmos-sdk/pull/5820/) Removed method CloseDB from Keybase interface.
    * (client/rpc) [#6290](https://github.com/cosmos/cosmos-sdk/pull/6290) `client` package and subdirs reorganization.
    * (client/lcd) [#6290](https://github.com/cosmos/cosmos-sdk/pull/6290) `CliCtx` of struct `RestServer` in package client/lcd has been renamed to `ClientCtx`.
    * (codec) [#6330](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/issues/6780) Move ledger code to its own package.
    * (crypto/types/multisig) [#6373](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/5880) Merge `crypto/keys/mintkey` into `crypto`.
    * (crypto/hd) [#5904](https://github.com/cosmos/cosmos-sdk/pull/5904) `crypto/keys/hd` moved to `crypto/hd`.
    * (crypto/keyring):
    _ [#5866](https://github.com/cosmos/cosmos-sdk/pull/5866) Rename `crypto/keys/` to `crypto/keyring/`.
    _ [#5904](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/tree/master/crypto/keyring/doc.go) for more
    information on how to implement the new `Keyring` interface. \* [#5858](https://github.com/cosmos/cosmos-sdk/pull/5858) Make Keyring store keys by name and address's hexbytes representation.
    * (export) [#5952](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/5803) The `store.CommitMultiStore` interface now includes the new `snapshots.Snapshotter` interface as well.
    * (types) [#5579](https://github.com/cosmos/cosmos-sdk/pull/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](https://github.com/cosmos/cosmos-sdk/pull/5533) Refactored `AppModuleBasic` and `AppModuleGenesis`
    to now accept a `codec.JSONMarshaler` for modular serialization of genesis state.
    * (types/rest) [#5779](https://github.com/cosmos/cosmos-sdk/pull/5779) Drop unused Parse{Int64OrReturnBadRequest,QueryParamBool}() functions.
* **Modules**
    * (modules) [#7243](https://github.com/cosmos/cosmos-sdk/pull/7243) Rename `RegisterCodec` to `RegisterLegacyAminoCodec` and `codec.New()` is now renamed to `codec.NewLegacyAmino()`
    * (modules) [#6564](https://github.com/cosmos/cosmos-sdk/pull/6564) Constant `DefaultParamspace` is removed from all modules, use ModuleName instead.
    * (modules) [#5989](https://github.com/cosmos/cosmos-sdk/pull/5989) `AppModuleBasic.GetTxCmd` now takes a single `CLIContext` parameter.
    * (modules) [#5664](https://github.com/cosmos/cosmos-sdk/pull/5664) Remove amino `Codec` from simulation `StoreDecoder`, which now returns a function closure in order to unmarshal the key-value pairs.
    * (modules) [#5555](https://github.com/cosmos/cosmos-sdk/pull/5555) Move `x/auth/client/utils/` types and functions to `x/auth/client/`.
    * (modules) [#5572](https://github.com/cosmos/cosmos-sdk/pull/5572) Move account balance logic and APIs from `x/auth` to `x/bank`.
    * (modules) [#6326](https://github.com/cosmos/cosmos-sdk/pull/6326) `AppModuleBasic.GetQueryCmd` now takes a single `client.Context` parameter.

    * (modules) [#6734](https://github.com/cosmos/cosmos-sdk/issues/6834) Add `TxEncodingConfig` parameter to `AppModuleBasic.ValidateGenesis` command to support JSON tx decoding in `genutil`.
    * (modules) [#7764](https://github.com/cosmos/cosmos-sdk/pull/7764) Added module initialization options:
        * `server/types.AppExporter` requires extra argument: `AppOptions`.
        * `server.AddCommands` requires extra argument: `addStartFlags types.ModuleInitFlags`
        * `x/crisis.NewAppModule` has a new attribute: `skipGenesisInvariants`. [PR](https://github.com/cosmos/cosmos-sdk/pull/7764)
    * (types) [#6327](https://github.com/cosmos/cosmos-sdk/pull/6327) `sdk.Msg` now inherits `proto.Message`, as a result all `sdk.Msg` types now use pointer semantics.
    * (types) [#7032](https://github.com/cosmos/cosmos-sdk/pull/7032) All types ending with `ID` (e.g. `ProposalID`) now end with `Id` (e.g. `ProposalId`), to match default Protobuf generated format. Also see [#7033](https://github.com/cosmos/cosmos-sdk/pull/7033) for more details.
    * (x/auth) [#6029](https://github.com/cosmos/cosmos-sdk/pull/6029) Module accounts have been moved from `x/supply` to `x/auth`.
    * (x/auth) [#6443](https://github.com/cosmos/cosmos-sdk/issues/6443) Move `FeeTx` and `TxWithMemo` interfaces from `x/auth/ante` to `types`.
    * (x/auth) [#7006](https://github.com/cosmos/cosmos-sdk/pull/7006) All `AccountRetriever` methods now take `client.Context` as a parameter instead of as a struct member.
    * (x/auth) [#6270](https://github.com/cosmos/cosmos-sdk/pull/6270) The passphrase argument has been removed from the signature of the following functions and methods: `BuildAndSign`, ` MakeSignature`, ` SignStdTx`, `TxBuilder.BuildAndSign`, `TxBuilder.Sign`, `TxBuilder.SignStdTx`
    * (x/auth) [#6428](https://github.com/cosmos/cosmos-sdk/issues/6428):
        * `NewAnteHandler` and `NewSigVerificationDecorator` both now take a `SignModeHandler` parameter.
        * `SignatureVerificationGasConsumer` now has the signature: `func(meter sdk.GasMeter, sig signing.SignatureV2, params types.Params) error`.
        * The `SigVerifiableTx` interface now has a `GetSignaturesV2() ([]signing.SignatureV2, error)` method and no longer has the `GetSignBytes` method.
    * (x/auth/tx) [#8106](https://github.com/cosmos/cosmos-sdk/pull/8106) change related to missing append functionality in
    client transaction signing
        * added `overwriteSig` argument to `x/auth/client.SignTx` and `client/tx.Sign` functions.
        * removed `x/auth/tx.go:wrapper.GetSignatures`. The `wrapper` provides `TxBuilder` functionality, and it's a private
      structure. That function was not used at all and it's not exposed through the `TxBuilder` interface.
    * (x/bank) [#7327](https://github.com/cosmos/cosmos-sdk/pull/7327) AddCoins and SubtractCoins no longer return a resultingValue and will only return an error.
    * (x/capability) [#7918](https://github.com/cosmos/cosmos-sdk/pull/7918) Add x/capability safety checks:
        * All outward facing APIs will now check that capability is not nil and name is not empty before performing any state-machine changes
        * `SetIndex` has been renamed to `InitializeIndex`
    * (x/evidence) [#7251](https://github.com/cosmos/cosmos-sdk/pull/7251) New evidence types and light client evidence handling. The module function names changed.
    * (x/evidence) [#5952](https://github.com/cosmos/cosmos-sdk/pull/5952) Remove APIs for getting and setting `x/evidence` parameters. `BaseApp` now uses a `ParamStore` to manage Tendermint consensus parameters which is managed via the `x/params` `Substore` type.
    * (x/gov) [#6147](https://github.com/cosmos/cosmos-sdk/pull/6147) The `Content` field on `Proposal` and `MsgSubmitProposal`
    is now `Any` in concordance with [ADR 019](docs/architecture/adr-019-protobuf-state-encoding.md) and `GetContent` should now

    _ Types of `int16` in the `Params` type are now of type `int32`.
    _ Every reference of `crypto.Pubkey` in context of a `Validator` is now of type string. `GetPubKeyFromBech32` must be used to get the `crypto.Pubkey`.
    _ The `Keeper` constructor now takes a `codec.Marshaler` instead of a concrete Amino codec. This exact type
    provided is specified by `ModuleCdc`.

    pagination.
    * (x/staking) [#8178](https://github.com/cosmos/cosmos-sdk/pull/8178) Update default historical header number for stargate
* **General**
    * (crypto) [#7987](https://github.com/cosmos/cosmos-sdk/pull/7987) Fix the inconsistency of CryptoCdc, only use
    `codec/legacy.Cdc`.
    * (logging) [#8072](https://github.com/cosmos/cosmos-sdk/pull/8072) Refactor logging:
    _ Use [zerolog](https://github.com/rs/zerolog) over Tendermint's go-kit logging wrapper.
    _ Introduce Tendermint's `--log_format=plain|json` flag. Using format `json` allows for emitting structured JSON
    logs which can be consumed by an external logging facility (e.g. Loggly). Both formats log to STDERR. \* The existing `--log_level` flag and it's default value now solely relates to the global logging
    level (e.g. `info`, `debug`, etc...) instead of `<module>:<level>`.
