Changelog

All notable changes to this project will be documented in this file. The format is based on Keep a Changelog.

Unreleased

Changed

  • Remove filesystem I/O functionality from the std feature, and gated this behind a new feature std-fs-io which depends upon std.

4.0.1

Added

  • Add a new SyncHandling enum, which allows a node to opt out of historical sync.

Changed

  • Update k256 to version 0.13.1.

Removed

  • Remove ExecutionResult::successful_transfers.

Security

3.0.0

Added

  • Add new bytesrepr::Error::NotRepresentable error variant that represents values that are not representable by the serialization format.
  • Add new Key::Unbond key variant under which the new unbonding information (to support redelegation) is written.
  • Add new Key::ChainspecRegistry key variant under which the ChainspecRegistry is written.
  • Add new Key::ChecksumRegistry key variant under which a registry of checksums for a given block is written. There are two checksums in the registry, one for the execution results and the other for the approvals of all deploys in the block.
  • Add new StoredValue::Unbonding variant to support redelegating.
  • Add a new type WithdrawPurses which is meant to represent UnbondingPurses as they exist in current live networks.

Changed

  • Extend UnbondingPurse to take a new field new_validator which represents the validator to whom tokens will be re-delegated.
  • Increase DICTIONARY_ITEM_KEY_MAX_LENGTH to 128.
  • Change prefix of formatted string representation of ContractPackageHash from "contract-package-wasm" to "contract-package-". Parsing from the old format is still supported.
  • Apply #[non_exhaustive] to error enums.
  • Change Debug output of DeployHash to hex-encoded string rather than a list of integers.

Fixed

  • Fix some integer casts, where failure is now detected and reported via new error variant NotRepresentable.

2.0.0

Fixed

  • Republish v1.6.0 as v2.0.0 due to missed breaking change in API (addition of new variant to Key).

1.6.0 [YANKED]

Added

  • Extend asymmetric key functionality, available via feature std (moved from casper-nodes crate).
  • Provide Timestamp and TimeDiff types for time operations, with extended functionality available via feature std (moved from casper-nodes crate).
  • Provide test-only functionality, in particular a seedable RNG TestRng which outputs its seed on test failure. Available via a new feature testing.
  • Add new Key::EraSummary key variant under which the era summary info is written on each switch block execution.

Deprecated

  • Deprecate gens feature: its functionality is included in the new testing feature.

1.5.0

Added

  • Provide types and functionality to support improved access control inside execution engine.
  • Provide CLTyped impl for ContractPackage to allow it to be passed into contracts.

Fixed

  • Limit parsing of CLTyped objects to a maximum of 50 types deep.

1.4.6 - 2021-12-29

Changed

  • Disable checksummed-hex encoding, but leave checksummed-hex decoding in place.

1.4.5 - 2021-12-06

Added

  • Add function to auction::MintProvider trait to support minting into an existing purse.

Changed

  • Change checksummed hex implementation to use 32 byte rather than 64 byte blake2b digests.

[1.4.4] - 2021-11-18

Fixed

  • Revert the accidental change to the std feature causing a broken build when this feature is enabled.

1.4.3 - 2021-11-17 [YANKED]

1.4.2 - 2021-11-13 [YANKED]

Added

  • Add checksummed hex encoding following a scheme similar to EIP-55.

1.4.1 - 2021-10-23

No changes.

1.4.0 - 2021-10-21 [YANKED]

Added

  • Add json-schema feature, disabled by default, to enable many types to be used to produce JSON-schema data.
  • Add implicit datasize feature, disabled by default, to enable many types to derive the DataSize trait.
  • Add StoredValue types to this crate.

Changed

  • Support building and testing using stable Rust.
  • Allow longer hex string to be presented in json files. Current maximum is increased from 100 to 150 characters.
  • Improve documentation and Debug impls for ApiError.

Deprecated

  • Feature std is deprecated as it is now a no-op, since there is no benefit to linking the std lib via this crate.

1.3.0 - 2021-07-19

Changed

  • Restrict summarization when JSON pretty-printing to contiguous long hex strings.
  • Update pinned version of Rust to nightly-2021-06-17.

Removed

1.2.0 - 2021-05-27

Changed

  • Change to Apache 2.0 license.
  • Return a Result from the constructor of SecretKey rather than potentially panicking.
  • Improve Key error reporting and tests.
