v1.4.0

Compare Source

Added

• cosmwasm-std: Implement Not for Uint{64,128,256} (#​1799).
• cosmwasm-std: Add iterators for Coins (#​1806).
• cosmwasm-std: Make abs_diff const for Uint{256,512} and
  Int{64,128,256,512}. It is now const for all integer types.
• cosmwasm-std: Implement TryFrom<Decimal256> for Decimal (#​1832)
• cosmwasm-std: Add StdAck. (#​1512)
• cosmwasm-std: Add new imports db_next_{key, value} for iterating storage
  keys / values only and make Storage::{range_keys, range_values} more
  efficient. This requires the cosmwasm_1_4 feature to be enabled. (#​1834)
• cosmwasm-std: Add
  DistributionQuery::{DelegationRewards, DelegationTotalRewards, DelegatorValidators}.
  This requires the cosmwasm_1_4 feature to be enabled. (#​1788)

Changed

• cosmwasm-vm: Avoid using loupe for getting the Module size in the file
  system cache to prepare for the Wasmer 3 upgrade.
• cosmwasm-vm: When enabling print_debug the debug logs are now printed to
  STDERR instead of STDOUT by default (#​1667).
• cosmwasm-vm: Add Instance::set_debug_handler/unset_debug_handler to allow
  customizing the handling of debug messages emitted by the contract (#​1667).
• cosmwasm-vm: Upgrade Wasmer to version 4.1. (#​1674, #​1693, #​1701,
  #​1793)
• cosmwasm-check: Update clap dependency to version 4 (#​1677)
• cosmwasm-vm: Use wasmparser for initial validation instead of parity-wasm
  (#​1786)
• cosmwasm-std: Make constructors Decimal{,256}::{percent,permille,bps} const
• cosmwasm-std: Use new db_next_key import to make skip and nth
  implementation of range iterators more efficient. This requires the
  cosmwasm_1_4 feature to be enabled. (#​1838)

v1.3.3

Compare Source

Added

• cosmwasm-std: Implement into_empty for QuerierWrapper, Deps and
  DepsMut.

v1.3.2

Compare Source

Fixed

• cosmwasm-std: Export CoinFromStrError, CoinsError and DivisionError

v1.3.1

Compare Source

Fixed

• cosmwasm-std: Export DelegatorWithdrawAddressResponse,
  DenomMetadataResponse and AllDenomMetadataResponse which were added in
  1.3.0 (#​1795).

Changed

• cosmwasm-std: Query responses are now exported, even if the corresponding
  cargo feature is not enabled (#​1795).

v1.3.0

Compare Source

Fixed

• cosmwasm-vm: Add missing cache stats increment when calling pin.

Added

• cosmwasm-std: Implement BankQuery::AllDenomMetadata to allow querying all
  the denom metadata and BankQuery::DenomMetadata to query a specific one. In
  order to use this query in a contract, the cosmwasm_1_3 feature needs to be
  enabled for the cosmwasm_std dependency. This makes the contract
  incompatible with chains running anything lower than CosmWasm 1.3.0.
  (#​1647)
• cosmwasm-std: Add DistributionQuery::DelegatorWithdrawAddress. Also needs
  the cosmwasm_1_3 feature (see above). (#​1593)
• cosmwasm-std: Add DistributionMsg::FundCommunityPool. Also needs the
  cosmwasm_1_3 feature (see above). (#​1747)
• cosmwasm-std: Add FromStr impl for Coin. (#​1684)
• cosmwasm-std: Add Coins helper to handle multiple coins. (#​1687)
• cosmwasm-vm: Add Cache::save_wasm_unchecked to save Wasm blobs that have
  been checked before. This is useful for state-sync where we know the Wasm code
  was checked when it was first uploaded. (#​1635)
• cosmwasm-vm: Allow sign extension Wasm opcodes in static validation. This
  allows contracts to be compiled with Rust 1.70.0 and above. (#​1727)
• cosmwasm-std: Add trait functions Storage::range_keys and
  Storage::range_values. The default implementations just use
  Storage::range. Later this can be implemented more efficiently. (#​1748)
• cosmwasm-std: Add Int64, Int128, Int256 and Int512 signed integer
  types. (#​1718)

Changed

• cosmwasm-vm: Add checks for table section of Wasm blob (#​1631).
• cosmwasm-vm: Limit number of imports during static validation (#​1629).
• cosmwasm-vm: Add target (triple + CPU features) into the module cache
  directory to avoid using modules compiled for a different system. Bump
  MODULE_SERIALIZATION_VERSION to "v6". (#​1664)
• cosmwasm-vm: Add .wasm extension to stored wasm files (#​1686).

Deprecated

• cosmwasm-storage: All exports are deprecated because this crate will be
  removed with CosmWasm 2.0 (#​1596).

v1.2.7

Compare Source

Added

• cosmwasm-std: Add << and <<= implementation for Uint{64,128,256,512}
  types. (#​1723)
• cosmwasm-std: Add Timestamp::{plus,minus}_{minutes, hours, days}. (#​1729)
• cosmwasm-std: Add Decimal::bps and Decimal256::bps to create a decimal
  from a basis point value (#​1715).

Changed

• cosmwasm-std: Coin uses shorter Coin { 123 "ucosm" } format for Debug
  (#​1704)

v1.2.6

Compare Source

Changed

• cosmwasm-vm: Bumped module serialization version from v4 to v5 to invalidate
  potentially corrupted caches caused by Rust update. https://github.com/CosmWasm/wasmvm/issues/426sues/426 for more information. (#​1708)

v1.2.5

Compare Source

Added

• cosmwasm-std: Implement PartialEq for Addr == &Addr and &Addr == Addr as
  well as Event == &Event and &Event == Event (#​1672).
• cosmwasm-std: Add #[must_use] annotations to Uint64, Uint128, Uint256,
  Uint512, Decimal and Decimal256 math operations (#​1678)

Deprecated

• cosmwasm-std: The PartialEq implementations between Addr and &str/String
  are deprecated because they are not considered to be safe. In almost all cases
  you want to convert both sides of the equation to Addr first. If you really
  want to do a string comparison, use Addr::as_str() explicitly. (#​1671)

v1.2.4

Compare Source

Fixed

• cosmwasm-vm: Add call depths limit

v1.2.3

Compare Source

• cosmwasm-vm: Use saturating increments for Stats fields to ensure we don't
  run into overflow issues.

v1.2.2

Compare Source

Added

• cosmwasm-std: Add an IBC querier implementation to testing::MockQuerier
  (#​1620, #​1624).
• cosmwasm-std: Add #[must_use] annotations to Timestamp math functions.

Fixed

• all: Fix backtraces feature for newer versions of Rust. This still requires
  Rust nightly (#​1613).
• cosmwasm-std: Add missing export CheckedMultiplyFractionError (#​1608).

v1.2.1

Compare Source

Added

• cosmwasm-std: Add Decimal{,256}::to_uint_floor and ::to_uint_ceil for
  efficient and explicit decimal to uint conversion (#​1603).

Fixed

• cosmwasm-std: Make fields of WeightedVoteOption public to allow constructing
  it (#​1597).

Changed

• cosmwasm-std: Improve readability of Debug output for Decimal and
  Decimal256 (#​1600).

v1.2.0

Compare Source

Added

• cosmwasm-std: Add GovMsg::VoteWeighted. In order to use this in a contract,
  the cosmwasm_1_2 feature needs to be enabled for the cosmwasm_std
  dependency. This makes the contract incompatible with chains running versions
  of CosmWasm earlier than 1.2.0 (#​1481).
• cosmwasm-std: Add instantiate2_address which allows calculating the
  predictable addresses for MsgInstantiateContract2 (#​1437, #​1554).
• cosmwasm-std: Add WasmMsg::Instantiate2 (requires cosmwasm_1_2, see
  GovMsg::VoteWeighted above) to instantiate contracts at a predictable
  address (#​1436, #​1554)).
• cosmwasm-schema: In contracts, cosmwasm schema will now output a separate
  JSON Schema file for each entrypoint in the raw subdirectory (#​1478,
  #​1533).
• cosmwasm-std: Upgrade serde-json-wasm dependency to 0.5.0 which adds map
  support to to_vec/to_binary and friends.
• cosmwasm-std: Implement AsRef<[u8]> for Binary and HexBinary (#​1550).
• cosmwasm-std: Allow constructing SupplyResponse via a Default
  implementation (#​1552, #​1560).
• cosmwasm-std: Add Never type which cannot be instantiated. This can be used
  as the error type for ibc_packet_receive or ibc_packet_ack to gain
  confidence that the implementations never errors and the transaction does not
  get reverted. (#​1513)
• cosmwasm-std: Add new WasmQuery::CodeInfo to get the checksum of a code ID
  (#​1561).
• cosmwasm-vm: Add Cache::remove_wasm to remove obsolete Wasm blobs and their
  compiled modules.
• cosmwasm-std: Implement fraction multiplication and division. Assists with
  Uint & Decimal arithmetic and exposes methods for flooring/ceiling result
  (#​1485, #​1566).

Changed

• cosmwasm-vm: Avoid exposing OS specific file system errors in order to test
  cosmwasm-vm on Windows. This gives us confidence for integrating cosmwasm-vm
  in a libwasmvm build on Windows. This change is likely to be consensus
  breaking as error messages change. (#​1406)
• cosmwasm-vm: Use Display representation for embedding Wasmer
  InstantiationErrors (#​1508).

Fixed

• cosmwasm-schema: Nested QueryMsg with generics is now supported by the
  QueryResponses macro (#​1516).
• cosmwasm-schema: A nested QueryMsg no longer causes runtime errors if it
  contains doc comments.
• cosmwasm-std/cosmwasm-vm: Increase length limit for address conversion in
  MockApi to support addresses longer than 54 bytes (#​1529).
