Changed

• cosmwasm-std: Deprecate abort feature. The panic handler is now always enabled (#2384).

Fixed

• cosmwasm-vm: Fix CWA-2025-003.

Added

• cosmwasm-std: Implement From<Uint64> for u{64,128}, From<Uint128> for u128, From<Int64> for i{64,128}, and From<Int128> for i128 (#2268)
• cosmwasm-std: Implement Uint128::from_{be,le}_bytes and Uint64::from_{be,le}_bytes. (#2269)

Fixed

• cosmwasm-vm: Fix CWA-2025-002.

Added

• cosmwasm-std: Add from_msgpack, to_msgpack_vec and to_msgpack_binary. These functions are meant to be used similarly to their JSON counterparts. MessagePack is a more compact, binary encoding. (#2118)
• cosmwasm-std: Add IbcMsg::{PayPacketFee, PayPacketFeeAsync} and IbcQuery::FeeEnabledChannel to allow contracts to incentivize IBC packets using IBC Fees. (#2196)
• cosmwasm-vm: Add Config that allows to configure the limits for static Wasm validation. (#2220)

• cosmwasm-vm: Add Cache::store_code

Changed

• cosmwasm-std: Binary, HexBinary and Checksum are now encoded as binary blobs when used together with a "compact" serde encoding. A compact encoding is an encoding that returns false from is_human_readable. This is to make these types more efficient when used together with the new MessagePack encoding. (#2118)

• cosmwasm-std: Let mock_env return a contract address that is valid bech32 and uses the same bech32 prefix as MockApi; Change MOCK_CONTRACT_ADDR value to match the contract address from mock_env. (#2211)

• cosmwasm-vm: Let mock_env return a contract address that is valid bech32 and uses the same bech32 prefix as MockApi; Change MOCK_CONTRACT_ADDR value to match the contract address from mock_env. (#2211)

• cosmwasm-derive: Automatically detect whether the package is a dependency or the primary package, only expanding entrypoints for the primary package. This effectively deprecates the usage of the library feature pattern.

  Note: This feature does NOT interact well with workspaces due to a cargo bug. If you have multiple contracts in a workspace, you might still want to use the library feature (#2246)

• cosmwasm-std: Deprecate BankQuery::AllBalances and IbcQuery::ListChannels. Both are inherently problematic to use because the returned entries are unbounded. (#2247)

• cosmwasm-vm: Upgrade Wasmer to 4.3.7; Bump MODULE_SERIALIZATION_VERSION to "v20". (#2255)

• cosmwasm-vm: Effectively remove the cranelift feature. It still exists but is only a no-op for semver compatibility. It will now unconditionally use the singlepass compiler. (#2260)

• cosmwasm-vm: Automatically derive cache version from function hashes and the Wasmer version (#2250)

• cosmwasm-vm: Add Cache::store_code

Fixed

• cosmwasm-vm: Add bls12_381_aggregate_g1, bls12_381_aggregate_g2, bls12_381_pairing_equality, bls12_381_hash_to_g1, and bls12_381_hash_to_g2 to enable BLS12-381 curve operations, such as verifying pairing equalities (#2106)
• cosmwasm-std: Add IBC Callbacks support, including two new entrypoints ibc_source_callback and ibc_destination_callback, as well as the IbcCallbackRequest type. (#2025)
