cosmwasm-derive

Fixed

• cosmwasm-schema: Using QueryResponses with a QueryMsg containing a unit-like variant will no longer crash. The different variant types in Rust are:

  enum QueryMsg {
      UnitLike,
      Tuple(),
      Struct {},
  }
  

  It's still recommended to only use struct variants, even if there are no fields.

Changed

• cosmwasm-schema: It is no longer necessary to specify serde or schemars as a dependency in order to make cosmwasm-schema macros work.

Added

• cosmwasm-std: Implement PartialEq for Binary and u8 arrays.
• cosmwasm-std: Add Uint{64,128,256,512}::one.
• cosmwasm-std: Add Uint{64,128,256,512}::abs_diff and Decimal{,256}::abs_diff (#1334).
• cosmwasm-std: Implement From<Decimal> for Decimal256.
• cosmwasm-std: Implement Rem/RemAssign for Decimal/Decimal256.
• cosmwasm-std: Implement checked_add/_sub/_div/_rem for Decimal/Decimal256.
• cosmwasm-std: Implement pow/saturating_pow for Decimal/Decimal256.
• cosmwasm-std: Implement ceil/floor for Decimal/Decimal256.
• cosmwasm-std: Implement PartialEq for reference on one side and owned value on the other for all Uint and Decimal types
• cosmwasm-std: Implement saturating_add/sub/mul for Decimal/Decimal256.
• cosmwasm-std: Implement BankQuery::Supply to allow querying the total supply of a native token. In order to use this query in a contract, the cosmwasm_1_1 feature needs to be enabled for the cosmwasm_std dependency. This makes the contract incompatible with chains running CosmWasm 1.0. (#1356)
• cosmwasm-std: Implement MIN const value for all Uint and Decimal types
• cosmwasm-std: Implement checked_div_euclid for Uint256/Uint512
• cosmwasm-std: Add QuerierWrapper::query_wasm_contract_info - this is just a convenience helper for querying WasmQuery::ContractInfo.
• cosmwasm-check: This is a new binary package that allows running various CosmWasm compatibility checks on compiled .wasm files. See https://crates.io/crates/cosmwasm-check for usage info.

Changed

• cosmwasm-vm/cosmwasm-profiler: Upgrade Wasmer to 2.3.0.
• cosmwasm-std: Enable the abort feature by default. This provides more helpful panic messages via a custom panic handler.
• cosmwasm-std: Make Decimal{,256}::DECIMAL_PLACES a public u32 value.
• cosmwasm-crypto: Bumped k256 0.10.4 -> 0.11 and digest 0.9 -> 0.10 (#1374).
• cosmwasm-vm: Rename features to capabilities, including
  1. features_from_csv to capabilities_from_csv;
  2. CacheOptions::supported_features to CacheOptions::available_capabilities;
  3. MockInstanceOptions::supported_features to MockInstanceOptions::available_capabilities
  4. Instance::required_features to Instance::required_capabilities
  5. AnalysisReport::required_features to AnalysisReport::required_capabilities.

Deprecated

• cosmwasm-vm: The check_contract example was deprecated. Please use the new crate cosmwasm-check instead (#1371).

Added

• cosmwasm-std: Export DelegationResponse (#1301).
• cosmwasm-std: When the new abort feature is enabled, cosmwasm-std installs a panic handler that aborts the contract and passes the panic message to the host. The abort feature can only be used when deploying to chains that implement the import. For this reason, it's not yet enabled by default. (#1299)
• cosmwasm-vm: A new import abort is created to abort contract execution when requested by the contract. (#1299)
• cosmwasm-std: Add new ibc3 feature that allows to use IBC-Go V3 features, like version negotiation and exposing relayer address to the contract. Requires a compatible wasmd runtime (v0.27.0+) (#1302)
