v0.38.0

Version 0.38.0

The release adds no_std compatible canonical serialization/deserialization. Along with it, all crates were updated to be no_std compatible. The whole repository is now WASM and RiscV compatible.

Added

• #586: Added default_asset method to the ContractIdExt trait implementation, to mirror the default method on AssetId in the Sway std lib.

Changed

Breaking

• #578: Support no_std environments for fuel-crypto, falling back to a pure-Rust crypto implementation.
• #582: Make fuel-vm and fuel-tx crates compatible with no_std + alloc. This includes reworking all error handling that used std::io::Error, replacing some std::collection::{HashMap, HashSet} with hashbrown::{HashMap, HashSet} and many changes to feature-gating of APIs.
• #587: Replace thiserror dependency with derive_more, so that core::fmt::Display is implemented without the std feature. Removes std::io::Error trait impls from the affected types.
• #588: Re-worked the size calculation of the canonical serialization/deserialization.

Removed

• #588: Removed SerializedSize and SerializedFixedSize traits. Removed support for SIZE_NO_DYNAMIC and SIZE_STATIC. Removed enum attributes from derive macro for Serialize and Deserialize traits.

What's Changed

• no_std fuel-crypto by @Dentosal in #578
• Add default_asset method by @SwayStar123 in #586
• no_std support for fuel-tx and fuel-vm by @Dentosal in #582
• Replace thiserror with derive_more::Display by @Dentosal in #587
• Follow-up for canonical se/de after an additional round of review by @xgreenx in #588
• Release 0.38.0 by @Dentosal in #590

New Contributors

• @SwayStar123 made their first contribution in #586

Full Changelog: v0.37.0...v0.38.0

v0.37.0

Version 0.37.0

Breaking

• #573: Added base_asset_id as a required field to FeeParameters. base_asset_id is used to supply the ID of the base asset.
• #554: Removed debug feature from the fuel-vm. The debugger is always available and becomes active after calling any set_* method.
• #537: Use dependent cost for k256, s256, mcpi, scwq, swwq opcodes.
  These opcodes charged inadequately low costs in comparison to the amount of work.
  This change should make all transactions that used these opcodes much more expensive than before.
• #533: Use custom serialization for fuel-types to allow no_std compilation.

What's Changed

• Use dependent cost for missed opcodes by @xgreenx in #537
• Update CI RUST_VERSION to 1.72.0 by @bvrooman in #575
• Remove debug feature from fuel-vm and use debugger by default. by @xgreenx in #554
• fix: Fixed length input for BMT node_sum by @bvrooman in #574
• Use custom derive ser/de instead of std::io by @Dentosal in #533
• feat: Impl fmt::Display for canonical Error by @bvrooman in #580
• fix: Organize ConsensusParameters gas costs in alphabetical order by @bvrooman in #581
• feat: Configurable Base Asset ID by @bvrooman in #573
• Upgrade to version 0.37.0 by @bvrooman in #583

v0.35.4

Version 0.35.4

Fixed

• #548: Bumped dalek to 2.0.0 to fix security vulnerability.

What's Changed

• Bump dalek version to deal with security vulnerability by @MitchTurner in #548

Full Changelog: v0.35.3...v0.35.4

v0.36.1

Version 0.36.1

Changed

• #546: Improve debug formatting of instruction in panic receipts.

Fixed

• #547: Bump ed25519-dalek to 2.0.0 to deal with RustSec Advisory
• #524: Fix a crash in CCP instruction when overflowing contract bounds. Fix a bug in CCP where overflowing contract bounds in a different way would not actually copy the contract bytes, but just zeroes out the section. Fix a bug in LDC where it would revert the transaction when the contract bounds were exceeded, when it's just supposed to fill the rest of the bytes with zeroes.

What's Changed

• Instruction debug fmt improvements by @Dentosal in #546
• Fix a crash in CCP and zero-filling issues in CCP and LDC by @Dentosal in #524
• Bump dalek version because of RustSec Advisory by @MitchTurner in #547

v0.36.0

Version 0.36.0

Changed

• #525: The $hp register is no longer restored to it's previous value when returning from a call, making it possible to return heap-allocated types from CALL.
• #535: Add better test coverage for TR and TRO.

Breaking

• #514: Add ChainId and GasCosts to ConsensusParameters.
  Break down ConsensusParameters into sub-structs to match usage. Change signatures of functions to ask for
  necessary fields only.
• #532: The TRO instruction now reverts when attempting to send zero coins to an output. Panic reason of this TransferZeroCoins, and TR was changed to use the same panic reason as well.

Fixed

• #511: Changes multiple panic reasons to be more accurate, and internally refactors instruction fetch logic to be less error-prone.

• #529 #534: Enforcing async WASM initialization for all NPM wrapper packages.

v0.35.1

Release v0.35.1

The minor release to trigger publishing of the fuel-asm and fuel-types to npm.

Added

• #499: The wasm_bindgen support of fuel-asm and fuel-types.
  Each new release also publish a typescript analog of the fuel-asm and fuel-types crates to the npm.

What's Changed

• The wasm_bindgen support of fuel-asm and fuel-types by @xgreenx in #499
• Release v0.35.1 by @xgreenx in #517
• Fixing NPM-publish workflow by @arboleya in #519

Full Changelog: v0.35.0...v0.35.1

v0.35.0

Release v0.35.0

The release mostly fixes funding during the audit and integration with the bridge. But the release also contains some new features like:

• Asynchronous predicate estimation/verification.
• Multi-asset support per contract.
• Support Secp256r1 signature recovery and Ed25519 verificaiton.

Added

• #486: Adds ed25519 signature verification and secp256r1 signature recovery to fuel-crypto, and corresponding opcodes ED19 and ECR1 to fuel-vm.

• #500: Introduced ParallelExecutor trait
  and made available async versions of verify and estimate predicates.
  Updated tests to test for both parallel and sequential execution.
  Fixed a bug in transaction/check_predicate_owners.

Breaking

• #506: Added new Mint and Burn variants to Receipt enum.
  It affects serialization and deserialization with new variants.

Changed

Breaking

• #506: The mint and burn
  opcodes accept a new $rB register. It is a sub-identifier used to generate an
  AssetId by this rule.
  This feature allows having multi-asset per one contract. It is a huge breaking change, and
  after this point, ContractId can't be equal to AssetId.

  The conversion like AssetId::from(*contract_id) is no longer valid. Instead, the ContractId implements the ContractIdExt trait:

  /// Trait extends the functionality of the `ContractId` type.
  pub trait ContractIdExt {
      /// Creates an `AssetId` from the `ContractId` and `sub_id`.
      fn asset_id(&self, sub_id: &Bytes32) -> AssetId;
  }

• #506: The mint and burn
  opcodes affect the receipts_root of the Script transaction.

Removed

Breaking

• #486: Removes apparently unused Keystore and Signer traits from fuel-crypto. Also renames ECR opcode to ECK1.

Fixed

• #500: Fixed a bug where MessageCoinPredicate wasn't checked for in check_predicate_owners.

Breaking

• #502: The algorithm used by the
  binary Merkle tree for generating Merkle proofs has been updated to remove
  the leaf data from the proof set. This change allows BMT proofs to conform
  to the format expected by the Solidity contracts used for verifying proofs.

• #503: Use correct amount of gas in call
  receipts when limited by cgas. Before this change, the Receipt::Call could show an incorrect value for the gas limit.

• #504: The CROO and CSIZ opcodes require
  the existence of corresponding ContractId in the transaction's
  inputs(the same behavior as for the CROO opcode).

• #504: The size of the contract
  was incorrectly padded. It affects the end of the call frame in the memory,
  making it not 8 bytes align. Also, it affects the cost of the contract
  call(in some cases, we charged less in some more).

• #504: The charging for DependentCost
  was done incorrectly, devaluing the dep_per_unit part. After the fixing of
  this, the execution should become much more expensive.

• #505: The data field of the Receipt
  is not part of the canonical serialization and deserialization anymore. The SDK should use the
  Receipt type instead of OpaqueReceipt. The Receipt.raw_payload will be removed for the
  fuel-core 0.20. The data field is optional now. The SDK should update serialization and
  deserialization for MessageOut, LogData, and ReturnData receipts.

• #505: The len field of the Receipt
  is not padded anymore and represents an initial value.

All changes:
