6/6 Matcher changeTokenBalance accepts address strings In Waffle 4, you can mix and match both Wallet instances and just address strings in the parameters of the changeTokenBalance matcher.

5/6 Catch Solidity Custom Errors You can now assert your Smart Contract to revert with Custom Errors, checking the arguments as well.

4/6 Assert structs in event parameters Solidity Structs can be emitted as one of the parameters of an event. The updated emit.withArgs matcher is able to assert them as well.

3/6 Assert event argument by name Sometimes you want to test only some of the arguments of an event and don’t really care about the rest. Waffle 4 allows you to do that.

2/6 Chaining emit matchers Frequently, a single transaction can emit more than one blockchain event. In Waffle 4, you can assert many events on a single transaction.

1/6 Regular Expressions in revertedWith You can now use regular expressions in reason strings in the revertedWith matcher.
