9.0.0

Added

  • Added support for RewardsHandling to the execution engine testing crate
  • Added support for minimum_delegation_rate to the execution engine testing crate

7.0.1

Added

  • Provide from_chainspec_path and max_associated_keys helper methods on ChainspecConfig.
  • Provide functions for converting from ChainspecConfig to EngineConfig.
  • Provide try_exec method on WasmTestBuilder for fallible contract execution.
  • Provide PRODUCTION_CHAINSPEC_PATH: a lazy static defining the path to the production chainspec.toml file.

7.0.0

Added

  • Provide calculate_refund_amount on WasmTestBuilder.
  • Provide upgrade_with_upgrade_request_and_config on WasmTestBuilder.

6.0.0

Changed

  • Update casper-execution-engine dependency.
  • Handle evict items in the WasmTestBuilder when advancing eras or calling step.

5.0.0

Added

  • Add WasmTestBuilder::get_execution_journals method for returning execution journals for all test runs.
  • Add support to load values from a given Chainspec.
  • Add static and constants that represent Casper-mainnet chainspec values. These values will change as new ProtocolVersions are added. The current values reflect ones used in the 1.5.0 ProtocolVersion.
  • Add WasmTestBuilder::advance_era, WasmTestBuilder::advance_eras_by, and WasmTestBuilder::advance_eras_by_default_auction_delay to advance chain and run auction contract in test environment.

Changed

  • WasmTestBuilder::get_transforms is deprecated in favor of WasmTestBuilder::get_execution_journals.
  • deploy_hash field is now defaulted to a random value rather than zeros in DeployItemBuilder.

4.0.0

Changed

  • Update dependencies (in particular casper-types to v2.0.0 due to additional Key variant, requiring a major version bump here).

3.1.1

Changed

  • Update chainspec values used in PRODUCTION_RUN_GENESIS_REQUEST to match those of Mainnet protocol version 1.4.15.

  • Add support for commit_prune of casper-execution-engine.

3.0.0

Changed

  • Version bump only to match major version bump of casper-execution-engine dependency.

2.3.0 [YANKED]

Added

  • Add ChainspecConfig to support parsing a chainspec.

2.2.0

Added
