v0.59.0

Version 0.59.0

Added

• 871: Add expiration policy that prevent a transaction to be inserted after a given block height.
• 870: Add 3 new ZK-related opcodes: eadd (ecAdd on EVM), emul (ecMul on EVM), epar (ecPairing on EVM)
• 875: Updated wasm-bindgen to 0.2.97

Fixed

• 860: Fixed missing fuzzing coverage report in CI.

Breaking

• 863: Changed StorageRead::read to load a serialized value starting from a offset. The function returns an optional value equal to the number of bytes read when defined, or none if the offset specified in input is outside the boundaries of the serialized value read.
• 868: Fixed error message when having a nonexistent contract in inputs. Instead of saying "contract was in inputs, but doesn't exist", the message was just "contract not in inputs". Now there's a separate error for that.
• 837: Change diff function to get VM instance diff to a rollback_to that allow to fetch changes to make self -> previous state. However, this support the new memory management that allow memory to grow between instances instead of fixed memory size.

Changed

• 847: Changed interpreter::blockchain::load_contract_code and interpreter::blockchain::code_copy to use the new version of StorageRead::read where the contract is loaded into a buffer starting from an offset. The contract is copied directly into the portion of memory starting at the destination address, rather than having to be copied indirectly after being fetched from storage.
