# CHANGELOG

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to
[Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

### Fixed

- @cosmjs/cosmwasm-stargate: Fix `ContractCodeHistory` decoding when msg contains non-printable ASCII ([#1320]).

[#1320]: https://github.com/cosmos/cosmjs/pull/1320

## [0.29.3] - 2022-10-25

### Added

- @cosmjs/tendermint-rpc: Add `HttpBatchClient`, which implements `RpcClient`,
  supporting batch RPC requests ([#1300]).
- @cosmjs/encoding: Add `lossy` parameter to `fromUtf8` allowing the use of a
  replacement charater instead of throwing.
- @cosmjs/stargate: Add structured `Events`s to `IndexTx.events` and
  `DeliverTxResponse.events`.
- @cosmjs/cosmwasm-stargate: Add structured `Events`s field to
  `SigningCosmWasmClient`s transaction execution methods.

### Fixed

- @cosmjs/stargate: Fix Amino JSON encoding of the unset case of
  `commission_rate` and `min_self_delegation` in
  `MsgEditValidator`/`AminoMsgEditValidator`.

## [0.29.2] - 2022-10-13

### Added

- @cosmjs/amino: Add `encodeEd25519Pubkey` analogue to the existing
  `encodeSecp256k1Pubkey`.
- @cosmjs/proto-signing: Add Ed25519 support to `encodePubkey` and
  `anyToSinglePubkey`. Export `anyToSinglePubkey`.
- @cosmjs/utils: Add `isDefined` which checks for `undefined` in a
  TypeScript-friendly way.
- @cosmjs/stargate: Add missing `{is,}MsgBeginRedelegateEncodeObject`,
  `{is,MsgCreateValidatorEncodeObject}` and `{is,MsgEditValidatorEncodeObject}`.

[#1300]: https://github.com/cosmos/cosmjs/pull/1300

### Fixed

- @cosmjs/cosmwasm-stargate: Use type `JsonObject = any` for smart query
  requests and messages (in `WasmExtension.wasm.queryContractSmart`,
  `CosmWasmClient.queryContractSmart`, `SigningCosmWasmClient.instantiate`,
  `SigningCosmWasmClient.migrate`, `SigningCosmWasmClient.execute`). This
  reverts the type change done in CosmJS 0.23.0. ([#1281], [#1284])
- @cosmjs/cosmwasm-stargate: `AminoMsgCreateValidator` and
  `createStakingAminoConverters` were fixed after testing both
  `MsgCreateValidator` and `MsgEditValidator` in sign mode direct and Amino JSON
  ([#1290]).

[#1281]: https://github.com/cosmos/cosmjs/pull/1281
[#1284]: https://github.com/cosmos/cosmjs/pull/1284

## [0.28.9] - 2022-06-21

This version replaces the 0.28.8 release which was erroneously tagged as 0.26.8
and released to npm under that wrong version. In order to avoid further
confusion we give up the .8 patch version. Users should install `^0.28.9` for
all `@cosmjs/*` packages to be safe. Users of `^0.26` should upgrade to a more
recent minor version if they run into trouble.

## [0.28.8] - 2022-06-21

- @cosmjs/tendermint-rpc: Fix decoding validator updates due to slashing
  ([#1177]).

  integer range.
- @cosmjs/cosmwasm-stargate, @cosmjs/stargate, @cosmjs/proto-signing: Upgrade
  protobufjs to 6.11.

### Fixed

- @cosmjs/tendermint-rpc: Fix block results validator update decoder. ([#1151])

[#1151]: https://github.com/cosmos/cosmjs/issues/1151

## [0.28.4] - 2022-04-15

### Added

- @cosmjs/math: Add `Decimal.zero` and `Decimal.one` ([#1110]).

## [0.28.3] - 2022-04-11

### Added

- @cosmjs/encoding: Add missing export: `normalizeBech32`.

## [0.28.2] - 2022-04-07

### Added

- @cosmjs/encoding: Create `normalizeBech32`.
- @cosmjs/stargate: Added support for `MsgCreateVestingAccount` ([#1074]).
  Please note that Amino JSON signing is currently not available for this type

[#1074]: https://github.com/cosmos/cosmjs/issues/1074
[#1115]: https://github.com/cosmos/cosmjs/issues/1115

## [0.28.1] - 2022-03-30

### Added

- @cosmjs/stargate: Added the ability to specify a custom account parser for
  `StargateClient`

### Fixed

- @cosmjs/proto-signing: Add missing runtime dependencies @cosmjs/encoding and
  @cosmjs/utils.
- @cosmjs/tendermint-rpc: Add missing runtime dependency @cosmjs/utils.

## [0.28.0] - 2022-03-17

### Changed

- all: The TypeScript compilation target is now ES2018.
- @cosmjs/crypto: Add `Secp256k1.uncompressPubkey`.
- @cosmjs/crypto: Replace hashing implementations with @noble/hashes ([#960]).
- @cosmjs/faucet: Set default value of `FAUCET_GAS_LIMIT` to 100_000 to better
  support Cosmos SDK 0.45 chains.
- @cosmjs/stargate: The `AminoTypes` now always requires an argument of type
  `AminoTypesOptions`. This is an object with a required `prefix` field. Before
  the prefix defaulted to "cosmos" but this is almost never the right choice for
  CosmJS users that need to add Amino types manually. ([#989])
- @cosmjs/cosmwasm-stargate: `height`, `gasWanted` and `gasUsed` have been added
  to all result types of `SigningCosmWasmClient`
- @cosmjs/stargate: `MsgSend` and `Coin` are now parts of
  `defaultRegistryTypes`. ([#994])
- @cosmjs/proto-signing: `Registry`'s constructor can now override default
  types. ([#994])
- @cosmjs/tendermint-rpc: The property `evidence` in the interface `Block` is
  now non-optional. ([#1011])
- @cosmjs/stargate: Added the following message types to stargate's
  `defaultRegistryTypes`: ([#1026])
  - cosmos.authz.v1beta1.MsgGrant
  - cosmos.authz.v1beta1.MsgExec
  - cosmos.authz.v1beta1.MsgRevoke
  - cosmos.feegrant.v1beta1.MsgGrantAllowance
  - cosmos.feegrant.v1beta1.MsgRevokeAllowance
- @cosmjs/stargate: In `AminoTypes` the uniqueness of the Amino type identifier
  is checked in `fromAmino` now instead of the constructor. This only affects
  you if multiple different protobuf type URLs map to the same Amino type
  identifier which should not be the case anyways.
- @cosmjs/stargate: Added support for slashing queries ([#927])
- @cosmjs/ledger-amino: Renamed `LaunchpadLedger` to `LedgerConnector` ([#955])
- @cosmjs/encoding: Created `toBech32()` and `fromBech32()`. Class Bech32 is now
  deprecated and should not longer be used. ([#1053])
- @cosmjs/crypto: Use a custom BIP-39 implementation to reduce external
  dependencies. This should also reduce the bundle size as only the English
  wordlist is shipped. ([#966])
- @cosmjs/cli: Rename binary `cosmwasm-cli` to `cosmjs-cli` ([#1033]).
- @cosmjs/stargate: Added Authz queries. ([#1080]).
- @cosmjs/stargate & @cosmjs/cosmwasm-stargate: Removed default types from
  AminoTypes. ([#1079])
- @cosmjs/cosmwasm-stargate: getCodes() automatically loops through all
  pagination pages now. ([#1077])
- @cosmjs/stargate & @cosmjs/cosmwasm-stargate: Timeout Errors shows more
  relevant information about the timeout. ([#1066])

[#1080]: https://github.com/cosmos/cosmjs/issues/1080

### Removed

- @cosmjs/crypto: Remove the SHA1 implementation (`Sha1` and `sha1`) as it is
  not used in the Cosmos tech stack and not implemented in the hashing lib we
  want to migrate to ([#1003]). Also it has known weaknesses.
- @cosmjs/launchpad: Package was removed as no support for Cosmos SDK 0.37-0.39
  is needed anymore ([#947]).

[#947]: https://github.com/cosmos/cosmjs/issues/947
[#1003]: https://github.com/cosmos/cosmjs/issues/1003

## [0.27.1] - 2022-01-26

### Added

- @cosmjs/cosmwasm-stargate: Add `fromBinary`/`toBinary` to convert between
  JavaScript objects and the JSON representation of `cosmwasm_std::Binary`
  (base64).
- @cosmjs/cosmwasm-stargate: Export `WasmExtension` and `setupWasmExtension`.
- @cosmjs/ledger-amino: Added `LedgerSigner.showAddress` and
  `LaunchpadLedger.showAddress` to show the user's address in the Ledger screen.

### Changed

- @cosmjs/stargate: The error messages for missing types in `AminoTypes` now
  contain the type that was searched for ([#990]).
- @cosmjs/tendermint-rpc: Change the `Evidence` type to `any` and avoid decoding
  it. The structure we had before was outdated and trying to decode it led to
  exceptions at runtime when a block with actual values was encountered.
  ([#980])

[#990]: https://github.com/cosmos/cosmjs/pull/990
[#980]: https://github.com/cosmos/cosmjs/issues/980

## [0.27.0] - 2022-01-10

### Added

- @cosmjs/tendermint-rpc: Add `hash` field to `BroadcastTxAsyncResponse`
  ([#938]).
- @cosmjs/stargate: Add `denomMetadata` and `denomsMetadata` to `BankExtension`
  ([#932]).
- @cosmjs/stargate: Merge `DeliverTxFailure` and `DeliverTxSuccess` into a
  single `DeliverTxResponse` ([#878], [#949]). Add `assertIsDeliverTxFailure`.
- @cosmjs/stargate: Created initial `MintExtension`.
- @cosmjs/stargate: Created `types.Dec` decoder function
  `decodeCosmosSdkDecFromProto`.
- @cosmjs/amino: Added `StdTx`, `isStdTx` and `makeStdTx` and removed them from
  @cosmjs/launchpad. They are re-exported in @cosmjs/launchpad for backwards
  compatibility.
- @cosmjs/stargate: Add `GasPrice.toString`.
- @cosmjs/faucet: Added a new functionality to faucet: Each address is only
  allowed to get credits once every 24h to prevent draining. ([#962]))

[#878]: https://github.com/cosmos/cosmjs/issues/878
[#949]: https://github.com/cosmos/cosmjs/issues/949

### Fixed

- @cosmjs/tendermint-rpc: Add missing `BlockSearchResponse` case to `Response`.

### Changed

- @cosmjs/stargate: Remove verified queries from `AuthExtension` and
  `BankExtension` as well as `StargateClient.getAccountVerified` because the
  storage layout is not stable across multiple Cosmos SDK releases. Verified
  queries remain available in the `IbcExtension` because for IBC the storage
  layout is standardized. Such queries can still be implemented in CosmJS caller
  code that only needs to support one backend. ([#865])
- @cosmjs/tendermint-rpc: Remove default URL from `HttpClient` and
  `WebsocketClient` constructors ([#897]).
- all: Upgrade cosmjs-types to 0.4. This includes the types of the Cosmos SDK
  0.44 modules x/authz and x/feegrant. It causes a few breaking changes by
  adding fields to interfaces as well as changing `Date` to a `Timestamp`
  object. ([#928])
- @cosmjs/stargate and @cosmjs/cosmwasm-stargate: Add simulation support
  ([#931]).
- @cosmjs/cosmwasm-stargate: Rename `BroadcastTx{Success,Failure}` to
  `DeliverTx{Success,Failure}`, `BroadcastTxResponse` to `DeliverTxResponse`,
  `isBroadcastTx{Success,Failure}` to `isDeliverTx{Success,Failure}` and
  `assertIsBroadcastTxSuccess` to `assertIsDeliverTxSuccess`. ([#946])
- @cosmjs/tendermint-rpc: Remove `Tendermint33Client` and related symbols.
- @cosmjs/cosmwasm-stargate: Add support for wasmd 0.21. This changes the AMINO
  JSON representation of `Msg{Execute,Instantiate,Migrate}Contract.msg` from
  base64 strings to JSON objects. ([#948])
- @cosmjs/cli: Replace `colors` dependency with `chalk` (see
  https://snyk.io/blog/open-source-npm-packages-colors-faker/)

## [0.26.6] - 2022-01-10

### Changed

- @cosmjs/cli: Replace `colors` dependency with `chalk` (see
  https://snyk.io/blog/open-source-npm-packages-colors-faker/)

## [0.26.5] - 2021-11-20

### Added

- @cosmjs/amino: The `coin` and `coins` helpers now support both `number` and
  `string` as input types for the amount. This is useful if your values exceed
  the safe integer range.

### Fixed

- @cosmjs/tendermint-rpc: Fix undefined `this` in `decodeBroadcastTxAsync` and
  `broadcastTxAsync` ([#937]).

[#937]: https://github.com/cosmos/cosmjs/pull/937

## [0.26.4] - 2021-10-28

### Fixed

- @cosmjs/cosmwasm-stargate: Fix response error handling for smart queries.

## [0.26.3] - 2021-10-25

### Added

- @cosmjs/ledger-amino: Add support for using forks of the Cosmos Ledger app by
  adding the fields `LaunchpadLedgerOptions.ledgerAppName` and
  `.minLedgerAppVersion`.

### Deprecated

- @cosmjs/stargate: The verified queries from `AuthExtension` and
  `BankExtension` as well as `StargateClient.getAccountVerified` are deprecated
  and will be removed in 0.27 ([#910]).

[#910]: https://github.com/cosmos/cosmjs/pull/910

## [0.26.2] - 2021-10-12

### Fixed

- @cosmjs/stargate: remove extra space in messageTimeout registry.
- @cosmjs/cosmwasm-stargate: Fix Amino JSON representation of
  `MsgInstantiateContract`, `MsgMigrateContract` and `MsgExecuteContract` to
  match the wasmd expectation. This was broken since the wasmd upgrade to
  Stargate such that no Ledger signing was possible for those message types in
  the meantime.

## [0.26.1] - 2021-09-30

### Added

- @cosmjs/amino: `decodeBech32Pubkey` and `decodeAminoPubkey` now support
  decoding multisig public keys ([#882]).

### Fixed

- @cosmjs/stargate: Add missing pagination key arguments to query types in
  `GovExtension`.

[#882]: https://github.com/cosmos/cosmjs/issues/882

## [0.26.0] - 2021-08-24

### Added

- @cosmjs/tendermint-rpc: `Tendermint34Client.blockSearch` and

- @cosmjs/tendermint-rpc: `Tendermint33Client` has been added to provide support
  for Tendermint v0.33.
- @cosmjs/tendermint-rpc: Exports relating to `Tendermint33Client` are now
  available under `tendermint33`.
- @cosmjs/proto-signing and @cosmjs/stargate: Create a Stargate-ready
  `parseCoins` that replaces the `parseCoins` re-export from `@cosmjs/amino`.
- @cosmjs/cosmwasm-stargate: Export `isValidBuilder`, which is a clone of
  `isValidBuilder` from @cosmjs/cosmwasm-launchpad.
- @cosmjs/cosmwasm-stargate: Copy symbols `Code`, `CodeDetails`, `Contract`,
  `ContractCodeHistoryEntry` and `JsonObject` from @cosmjs/cosmwasm-launchpad
  and remove dependency on @cosmjs/cosmwasm-launchpad.
- @cosmjs/faucet: Add new configuration variable `FAUCET_PATH_PATTERN` to
  configure the HD path of the faucet accounts ([#832]).
- @cosmjs/cosmwasm-stargate: Add field `ibcPortId` to `Contract` ([#836]).
- @cosmjs/stargate: Add `GovExtension` for query client.
- @cosmjs/stargate: Add support for `MsgDeposit`, `MsgSubmitProposal` and
  `MsgVote`.

[#832]: https://github.com/cosmos/cosmjs/issues/832
[#836]: https://github.com/cosmos/cosmjs/issues/836

- @cosmjs/cli: Now supports HTTPs URLs for `--init` code sources.
- @cosmjs/cli: Now supports adding code directly via `--code`.
- @cosmjs/cosmwasm: Rename `CosmWasmClient.getNonce` method to `.getSequence`.
- @cosmjs/cosmwasm: Remove `RestClient` class in favour of new modular
  `LcdClient` class from @cosmjs/sdk38.
- @cosmjs/cosmwasm: Add `SigningCosmWasmClient.signAndPost` as a mid-level
  abstraction between `SigningCosmWasmClient.upload`/`.instantiate`/`.execute`
  and `.postTx`.
- @cosmjs/cosmwasm: Use `*PostTx*` types and helpers from @cosmjs/sdk38. Remove
  exported `PostTxResult`.
- @cosmjs/cosmwasm: `ContractDetails` was removed in favour of just `Contract`.
  The missing `init_msg` is now available via the contract's code history (see
  `getContractCodeHistory`).
- @cosmjs/cosmwasm: Remove `SigningCallback` in favour of the `OfflineSigner`
  interface.
- @cosmjs/sdk38: Rename `CosmosClient.getNonce` method to `.getSequence`.
- @cosmjs/sdk38: Remove `RestClient` class in favour of new modular `LcdClient`
  class.
- @cosmjs/sdk38: Remove `Pen` type in favour of `OfflineSigner` and remove
  `Secp256k1Pen` class in favour of `Secp256k1Wallet` which takes an
  `OfflineSigner` instead of a `SigningCallback`.
- @cosmjs/sdk38: Rename `CosmosSdkAccount` to `BaseAccount` and export the type.
- @cosmjs/sdk38: `BaseAccount` now uses `number | string` as the type for
  `account_number` and `sequence`. The new helpers `uint64ToNumber` and
  `uint64ToString` allow you to normalize the mixed input.
- @cosmjs/sdk38: `BaseAccount` now uses `string | PubKey | null` as the type for
  `public_key`. The new helper `normalizePubkey` allows you to normalize the
  mixed input.
- @cosmjs/math: Add missing integer check to `Uint64.fromNumber`. Before
  `Uint64.fromNumber(1.1)` produced some result.
- @cosmjs/sdk38: Add `SigningCosmosClient.signAndPost` as a mid-level
  abstraction between `SigningCosmosClient.sendTokens` and `.postTx`.
- @cosmjs/sdk38: Export `PostTxFailure`/`PostTxSuccess` and type checkers
  `isPostTxFailure`/`isPostTxSuccess`; export `assertIsPostTxSuccess`.
- @cosmjs/sdk38: `Secp256k1Wallet`s can now be generated randomly with
  `Secp256k1Wallet.generate(n)` where `n` is 12, 15, 18, 21 or 24 mnemonic
  words.
- @cosmjs/sdk38: The new `Secp256k1Wallet.serialize` and `.deserialize` allow
  encrypted serialization of the wallet.
- @cosmjs/sdk38: Remove the obsolete `upload`, `init`, `exec` properties from
  `FeeTable`. @cosmjs/cosmwasm has its own `FeeTable` with those properties.
- @cosmjs/sdk38: Rename package to @cosmjs/launchpad.
