All notable changes to the tracing interface will be documented in this file.

## [Unreleased]

### Modified types

- `GasChangeReason` has been extended with the following reasons which will be enabled only post-Verkle. There shouldn't be any gas changes with those reasons prior to the fork.
- `GasChangeWitnessContractCollisionCheck` flags the event of adding to the witness when checking for contract address collision.

## [v1.14.4]

This release contained only minor extensions to the tracing interface.

### Modified types

- `GasChangeReason` has been extended with the following reasons that will only be active post-Verkle.
- `GasChangeWitnessContractInit` flags the event of adding to the witness during the contract creation initialization step.
- `GasChangeWitnessContractCreation` flags the event of adding to the witness during the contract creation finalization step.
- `GasChangeWitnessCodeChunk` flags the event of adding one or more contract code chunks to the witness.

## [v1.14.3]

There have been minor backwards-compatible changes to the tracing interface to explicitly mark the execution of **system** contracts. As of now the only system call updates the parent beacon block root as per [EIP-4788](https://eips.ethereum.org/EIPS/eip-4788). Other system calls are being considered for the future hardfork.

- `CaptureState` -> `OnOpcode(pc uint64, op byte, gas, cost uint64, scope tracing.OpContext, rData []byte, depth int, err error)`. `op` is of type `byte` which can be cast to `vm.OpCode` when necessary. A `*vm.ScopeContext` is not passed anymore. It is replaced by `tracing.OpContext` which offers access to the memory, stack and current contract.
- `CaptureFault` -> `OnFault(pc uint64, op byte, gas, cost uint64, scope tracing.OpContext, depth int, err error)`. Similar to above.
