Unreleased (node 1.5.4)

7.0.0

Added

  • Add chainspec option core.allow_unrestricted_transfers that, if enabled, allows token transfers between any two peers. Disabling this option makes sense only for private chains.
  • Add chainspec option core.allow_auction_bids that, if enabled, allows auction entrypoints delegate and add_bid to operate. Disabling this option makes sense only for private chains.
  • Add chainspec option core.compute_rewards that, if enabled, computes rewards for each era. Disabling this option makes sense only for private chains.
  • Add chainspec option core.refund_handling that specifies how payment refunds are handled.
  • Add chainspec option core.fee_handling that specifies how transaction fees are handled.
  • Add chainspec option core.administrators that, if set, contains list of administrator accounts. This option makes sense only for private chains.
  • Add support for a new FFI function enable_contract_version for enabling a specific version of a contract.

Changed

  • current stack height is written to stderr in case Trap(Unreachable) error is encountered during Wasm execution.
  • Tweak upgrade logic transforming withdraw purses to early exit if possible.
  • Lower the default gas costs of opcodes.
    • Set the cost for branching opcodes to 35,000 (br, br_if, br_table).
    • Set the cost for call opcodes to 68,000 (call, call_indirect).
  • Default value for round seigniorage rate is halved to 7/175070816 due to reduction in block times, to maintain current seigniorage rate (per unit of time).
  • Refund ratio is changed from 0% to 99%.

6.0.0

Changed

  • Default value for max_stack_height is increased to 500.
  • Replace usage of parity-wasm and wasmi with Casper forks casper-wasm and casper-wasmi respectively.

Fixed

  • Fix incorrect handling of unbonding purses for validators that were also evicted in that era.
  • Fix issue with one-time code used for migrating data to support redelegations.

Security

  • Fix unbounded memory allocation issue while parsing Wasm.

5.0.0

Added

  • Add a new entry point redelegate to the Auction system contract which allows users to redelegate to another validator without having to unbond. The function signature for the entrypoint is: redelegate(delegator: PublicKey, validator: PublicKey, amount: U512, new_validator: PublicKey)
  • Add a new type ChainspecRegistry which contains the hashes of the chainspec.toml and will optionally contain the hashes for accounts.toml and global_state.toml.
  • Add ability to enable strict args checking when executing a contract; i.e. that all non-optional args are provided and of the correct CLType.

Changed

  • Fix some integer casts.
  • Change both genesis and upgrade functions to write ChainspecRegistry under the fixed Key::ChainspecRegistry.
  • Lift the temporary limit of the size of individual values stored in global state.
  • Providing incorrect Wasm for execution will cause the default 2.5CSPR to be charged.
  • Update the default control_flow opcode cost from 440 to 440_000.

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 the following constant values to match settings in production chainspec:
    • DEFAULT_RET_VALUE_SIZE_WEIGHT
    • DEFAULT_CONTROL_FLOW_CALL_OPCODE
    • DEFAULT_CONTROL_FLOW_CALL_INDIRECT_OPCODE
    • DEFAULT_GAS_PER_BYTE_COST
    • DEFAULT_ADD_BID_COST
    • DEFAULT_WITHDRAW_BID_COST
    • DEFAULT_DELEGATE_COST
    • DEFAULT_UNDELEGATE_COST
    • DEFAULT_MAX_STACK_HEIGHT

3.1.0

Added

  • Add commit_prune functionality to support pruning of entries in global storage.

Changed

  • Update to use casper-wasm-utils; a patched fork of the archived wasm-utils.

3.0.0

Changed

  • Implement more precise control over opcode costs that lowers the gas cost.
  • Increase cost of withdraw_bid and undelegate auction entry points to 2.5CSPR.

2.0.1

Security

  • Implement checks before preprocessing Wasm to avoid potential OOM when initializing table section.
  • Implement checks before preprocessing Wasm to avoid references to undeclared functions or globals.
  • Implement checks before preprocessing Wasm to avoid possibility to import internal host functions.

2.0.0 - 2022-05-11

Changed

  • Change contract runtime to allow caching global state changes during execution of a single block, also avoiding writing interstitial data to global state.

1.5.0 - 2022-04-05

Changed

  • Temporarily limit the size of individual values stored in global state.

Security

  • amount argument is now required for transactions wanting to send tokens using account's main purse. It is now an upper limit on all tokens being transferred within the transaction.
  • Significant rework around the responsibilities of the executor, runtime and runtime context objects, with a focus on removing alternate execution paths where unintended escalation of privilege was possible.
  • Attenuate the main purse URef to remove WRITE permissions by default when returned via ret or passed as a runtime argument.
  • Fix a potential panic during Wasm preprocessing.
  • get_era_validators performs a query rather than execution.

1.4.4 - 2021-12-29

Changed

  • No longer checksum-hex encode hash digest and address types.

1.4.3 - 2021-12-06

Changed

  • Auction contract now handles minting into an existing purse.
  • Default maximum stack size in WasmConfig changed to 188.
  • Default behavior of LMDB changed to use NO_READAHEAD

Fixed

  • Fix a case where an unlocked and partially unbonded genesis validator with smaller stake incorrectly occupies slot for a non-genesis validator with higher stake.

1.4.2 - 2021-11-11

Changed

  • Execution transforms are returned in their insertion order.

Removed

  • Removed SystemContractCache as it was not being used anymore

1.4.0 - 2021-10-04

Added

  • Added genesis validation step to ensure there are more genesis validators than validator slots.
  • Added a support for passing a public key as a target argument in native transfers.
  • Added a max_associated_keys configuration option for a hard limit of associated keys under accounts.

Changed

  • Documented storage module and children.
  • Reduced visibility to pub(crate) in several areas, allowing some dead code to be noticed and pruned.
  • Support building and testing using stable Rust.
  • Increase price of create_purse to 2.5CSPR.
  • Increase price of native transfer to 100 million motes (0.1 CSPR).
  • Improve doc comments to clarify behavior of the bidding functionality.
  • Document core and shared modules and their children.
  • Change parameters to LmdbEnvironment's constructor enabling manual flushing to disk.

Fixed

  • Fix a case where user could potentially supply a refund purse as a payment purse.

1.3.0 - 2021-07-19

Changed

  • Update pinned version of Rust to nightly-2021-06-17.

1.2.0 - 2021-05-27

Added

  • Add validation that the delegated amount of each genesis account is non-zero.
  • Add activate-bid client contract.
  • Add a check in Mint::transfer that the source has Read permissions.

Changed

  • Change to Apache 2.0 license.
  • Remove the strict expectation that minor and patch protocol versions must always increase by 1.

Removed

  • Remove RootNotFound error struct.
