# 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]

### Added

- @cosmjs/stargate: Add support for different account types in `accountFromAny`
  and `StargateClient`. Added vesting accounts `BaseVestingAccount`,
  `ContinuousVestingAccount`, `DelayedVestingAccount` and
  `PeriodicVestingAccount`.

### Changed

- @cosmjs/cosmwasm-stargate: Codec adapted to support wasmd 0.16. Older versions
  of wasmd are not supported anymore.
- @cosmjs/stargate: Let `AuthExtension.account` and
  `AuthExtension.unverified.account` return an account of type `Any`. This makes
  the caller responsible for decoding the type.
- @cosmjs/stargate: Remove `accountFromProto` in favour of `accountFromAny`.
- @cosmjs/tendermint-rpc: The fields `CommitSignature.validatorAddress`,
  `.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.

## [0.24.0] - 2021-03-11

- @cosmjs/cosmwasm: This package is now deprecated. The same functionality is
  now available in @cosmjs/cosmwasm-launchpad.
- @cosmjs/cosmwasm: `logs` is no longer exported. Use `logs` from
  @cosmjs/launchpad instead.

  keypair.
- @cosmjs/launchpad: `OfflineSigner` type’s `sign` method renamed `signAmino`
  and `SignResponse` type renamed `AminoSignResponse`.
- @cosmjs/launchpad: `Secp256k1HdWallet.sign` method renamed `signAmino`.
- @cosmjs/launchpad: Add `CosmosClient.getTx` method for searching by ID and
  remove such functionality from `CosmosClient.searchTx`.

  `.signerAddress`.
- @cosmjs/proto-signing: Add new package for handling transaction signing with
  protobuf encoding.
- @cosmjs/proto-signing: Expose `DirectSignResponse` interface.
- @cosmjs/stargate: Add new package for Cosmos SDK Stargate support.
- @cosmjs/tendermint-rpc: Make `Client.detectVersion` private and let it return
  a version instead of a client.

  `Client.create` for creating a Tendermint client given an RPC client and an
  optional adaptor.
- @cosmjs/tendermint-rpc: Add an optional adaptor argument to `Client.connect`
  which allows skipping the auto-detection.
- @cosmjs/tendermint-rpc: Remove export `v0_33` in favour of `adaptor33` and
  `adaptor34`. Export the `Adaptor` type.
- @cosmjs/tendermint-rpc: Export `DateTime` class.
- @cosmjs/tendermint-rpc: Remove types `QueryString`, `Base64String`,
  `HexString`, `IntegerString` and `IpPortString`. Use `string` instead.
- @cosmjs/tendermint-rpc: Remove types `BlockHash`, `TxBytes` and `TxHash`. Use
  `Uint8Array` instead.

### Added

- @cosmjs/launchpad: Export distribution module msg types
  `MsgFundCommunityPool`, `MsgSetWithdrawAddress`, `MsgWithdrawDelegatorReward`,
  `MsgWithdrawValidatorCommission` and type checker helper functions.
- @cosmjs/utils: Added `assertDefinedAndNotNull`.
- @cosmjs/tendermint-rpc: The new `Tendermint34Client` is a copy of the old
  `Client` but without the automatic version detection. Its usage is encouraged
  over `Client` if you connect to a Tendermint 0.34 backend.

### Changed

- @cosmjs/encoding: Change return type of `fromRfc3339` from `ReadonlyDate` to
  `Date` as the caller becomes the owner of the object and can safely mutate it
  in any way.

- @cosmjs/cosmwasm: Rename `FeeTable` type to `CosmWasmFeeTable`.
- @cosmjs/cosmwasm: `SigningCosmWasmClient` constructor now takes optional
  arguments `gasPrice` and `gasLimits` instead of `customFees` for easier
  customization.
- @cosmjs/cosmwasm: Rename `SigningCosmWasmClient.signAndPost` method to
  `.signAndBroadcast`.
- @cosmjs/cosmwasm: Use stricter type `Record<string, unknown>` for smart query,

- @cosmjs/demo-staking: Remove package and supporting scripts.
- @cosmjs/encoding: Add `limit` parameter to `Bech32.encode` and `.decode`. The
  new default limit for decoding is infinity (was 90 before). Set it to 90 to
  create a strict decoder.

  `FAUCET_GAS_PRICE` and now only accepts one token. Environmental variable
  `FAUCET_GAS` renamed to `FAUCET_GAS_LIMIT`.

  `ticker` (unit token). Environmental variables specifying credit amounts now
  need to use uppercase denom.
- @cosmjs/launchpad: Rename `FeeTable` type to `CosmosFeeTable` and export a new
  more generic type `FeeTable`.
- @cosmjs/launchpad: Add new class `GasPrice`, new helper type `GasLimits` and
  new helper function `buildFeeTable` for easier handling of gas prices and
  fees.
- @cosmjs/launchpad: Rename `CosmosClient.postTx` method to `.broadcastTx`.
- @cosmjs/launchpad: `SigningCosmosClient` constructor now takes optional
  arguments `gasPrice` and `gasLimits` instead of `customFees` for easier

  `.signAndBroadcast`.
- @cosmjs/launchpad: Rename `PostTx`-related types to `BroadcastTxResult`,
  `BroadcastTxSuccess` and `BroadcastTxFailure` respectively, as well as helper
  functions `isBroadcastTxFailure`, `isBroadcastTxSuccess` and
  `assertIsBroadcastTxSuccess`.
- @cosmjs/launchpad: Export `isSearchByIdQuery`, `isSearchByHeightQuery`,
  `isSearchBySentFromOrToQuery` and `isSearchByTagsQuery`.
- @cosmjs/launchpad: Change type of `TxsResponse.logs` and
  `BroadcastTxsResponse.logs` to `unknown[]`.
- @cosmjs/launchpad: Export `StdSignDoc` and create helpers to make and
  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
  was signed.
- @cosmjs/launchpad: Remove `PrehashType` and the prehash type argument in
  `OfflineSigner.sign` because the signer now needs to know how to serialize an
  `StdSignDoc`.
- @cosmjs/launchpad: Remove `makeSignBytes` in favour of `makeSignDoc` and
  `serializeSignDoc`.
- @cosmjs/launchpad: Create `WrappedTx`, `WrappedStdTx` and `isWrappedStdTx` to
  better represent the Amino tx interface. Deprecate `CosmosSdkTx`, which is an
  alias for `WrappedStdTx`.
- @cosmjs/launchpad: Add `makeStdTx` to create an `StdTx`.
- @cosmjs/launchpad: Rename `Secp256k1Wallet` to `Secp256k1HdWallet`. Later on,
  we'll use `Secp256k1Wallet` for single key wallets.
- @cosmjs/launchpad-ledger: Add package supporting Ledger device integration for
  Launchpad. Two new classes are provided: `LedgerSigner` (for most use cases)
  and `LaunchpadLedger` for more fine-grained access.
- @cosmjs/math: Add `.multiply` method to `Decimal` class.
- @cosmjs/math: Deprecate `Uint32.fromBigEndianBytes` in favour of
  `Uint32.fromBytes`, which supports both big and little endian.

  `Uint64.fromBytes`, which supports both big and little endian.
- @cosmjs/math: Add `Uint32.fromString`.
- @cosmjs/tendermint-rpc: Make `BroadcastTxCommitResponse.height` non-optional.
- @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`.
- @cosmjs/tendermint-rpc: Remove obsolete `TxData.tags` and make `TxData.events`
  non-optional. Rename `Tag` to `Attribute`.
- @cosmjs/tendermint-rpc: Remove obsolete `BlockResultsResponse.beginBlock` and
  `.beginBlock`. The new `.beginBlockEvents` and `.endBlockEvents` now parse the
  events correctly.
- @cosmjs/tendermint-rpc: Remove trivial helpers `getTxEventHeight`,
  `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.
- @cosmjs/tendermint-rpc: Make `TxEvent.index` optional and deprecate it because
  it is not set anymore in Tendermint 0.34.

- @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`.

  `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.
