## [Unreleased]

### Changed

- all: The TypeScript compilation target is now ES2018.
- @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

[#1026]: https://github.com/cosmos/cosmjs/issues/1026

### 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.

[#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 The structure we had before was outdated and trying to decode it led to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])

[#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]))

[#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/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

  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

  be calculated and passed to `SigningStargateClient` when calling any methods
  which submit transactions to the blockchain.
- @cosmjs/tendermint-rpc: Make `tendermint34.Header.lastBlockId` and
  `tendermint34.Block.lastCommit` optional to better handle the case of height 1
  where there is no previous block.
- @cosmjs/proto-signing: `makeAuthInfoBytes` now takes an array of pubkey
  sequence pairs in order to support different sequences for different signers.
- @cosmjs/cosmwasm-stargate: Upgraded client to support wasmd 0.18 backends.
  Other backends are not supported anymore. Update proto types from
  `cosmwasm.wasm.v1beta1.*` to `cosmwasm.wasm.v1.*`. `MsgStoreCode.source` and
  `MsgStoreCode.builder` were removed; `MsgInstantiateContract.initMsg` and
  `MsgMigrateContract.migrateMsg` were renamed to `msg`; `Code.{source,builder}`
  and `CodeDetails.{source,builder}` were removed; `isValidBuilder` was removed;

### Added

- @cosmjs/tendermint-rpc: `Tendermint34Client.blockSearch` and
  `Tendermint34Client.blockSearchAll` were added to allow searching blocks in
  Tendermint 0.34.9+ backends. This is a backport of [#815]. Note: Decoding

  functionality for @cosmjs/launchpad and @cosmjs/stargate.
- @cosmjs/amino: Split public key interfaces into `Pubkey`, `SinglePubkey` and
  `Secp256k1Pubkey` where `Pubkey` is a generalization of the old `PubKey` that
  supported nested pubkeys for multisig. `SinglePubkey` is the old `PubKey` in
  which the `value` is a base64 encoded string. And `Secp256k1Pubkey` is a
  single secp256k1 pubkey.
- @cosmjs/utils: The new `arrayContentStartsWith` works similar to

  `.timestamp` and `.signature` are now optional. They are unset when
  `blockIdFlag` is `BlockIdFlag.Absent`. The decoding into `CommitSignature` is
  only updated for the class `Tendermint34Client`, not for `Client`. Please
  migrate to the former.
- @cosmjs/launchpad: `rawSecp256k1PubkeyToAddress` was removed. Instead use
  `Bech32.encode(prefix, rawSecp256k1PubkeyToRawAddress(pubkeyRaw))` with
  `rawSecp256k1PubkeyToRawAddress` from @cosmjs/amino.
- @cosmjs/stargate: `parseRawLog` is now nested under the `logs` export.

  verified queries nested under `.verified`.
- @cosmjs/cosmwasm-stargate: `wasm` extension now has unverified queries at the
  root.
- @cosmjs/stargate: `StargateClient.getAccount` now uses an unverified query and
  `StargateClient.getAccountUnverified` has been removed.

  now passed via a `DirectSecp256k1HdWalletOptions` object.
- @cosmjs/stargate: `StargateClient.broadcastTx` now uses sync mode and then
  polls for the transaction before resolving. The timeout and poll interval can
  be configured.
- @cosmjs/cosmwasm-stargate: `CosmWasmClient.broadcastTx` now uses sync mode and
  then polls for the transaction before resolving. The timeout and poll interval
  can be configured.

  `gasWanted`, and `gasUsed` properties.
- @cosmjs/amino: `Secp256k1HdWallet.fromMnemonic` now accepts a
  `Secp256k1HdWalletOptions` argument which includes an array of `hdPaths`
  instead of a single `hdPath`. `Secp256k1HdWallet.generate` now also accepts
  options via this interface. This adds support for multiple accounts from the
  same mnemonic to `Secp256k1HdWallet`.
- @cosmjs/proto-signing: `DirectSecp256k1HdWallet.fromMnemonic` now accepts a
  `DirectSecp256k1HdWalletOptions` argument which includes an array of `hdPaths`
  instead of a single `hdPath`. `DirectSecp256k1HdWallet.generate` now also
  accepts options via this interface. This adds support for multiple accounts
  from the same mnemonic to `DirectSecp256k1HdWallet`.
- @cosmjs/tendermint-rpc: `ValidatorPubkey` is now a union of
  `ValidatorEd25519Pubkey` and the newly exported `ValidatorSecp256k1Pubkey`
  interface.
- @cosmjs/tendermint-rpc: `decodePubkey` now supports secp256k1 public keys.

  do not need a Tendermint RPC client and Stargate applications should use
  `Tendermint34Client`.

### Removed

- @cosmjs/stargate: `coinFromProto` helper has been removed as it is no longer
  needed after the `ts-proto` migration.

  serialize a `StdSignDoc`: `makeSignDoc` and `serializeSignDoc`.
- @cosmjs/launchpad: Let `OfflineSigner.sign` take an `StdSignDoc` instead of an
  encoded message and return a `SignResponse` that includes the document which

- @cosmjs/tendermint-rpc: Make `TxProof.proof.leafHash` non-optional because it
  is always set.
- @cosmjs/tendermint-rpc: Change type of `GenesisResponse.appState` to
  `Record<string, unknown> | undefined`.

  `getHeaderEventHeight` and `getBlockEventHeight` because they don't do
  anything else than accessing an object member.
- @cosmjs/tendermint-rpc: Add support for connecting to Tendermint RPC 0.34.

  `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.

  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.
