This release includes new features and multiple optimizations that give a general performance improvement.

The new features include:

• Execution tracing support has been added for JS/TS integration tests, previously this was only available for Solidity tests. Tracing support is available through the --verbosity option and its -v shorthands. For more details see the execution traces docs.
• Inline configuration per test is now available in Solidity tests (see our inline config docs)
