### [`v4.3.0`](https://togithub.com/chaijs/chai/releases/tag/4.3.0): / 2021-02-04
[Compare Source](https://togithub.com/chaijs/chai/compare/4.2.0...4.3.0)
This is a minor release.
Not many changes have got in since the last release but this one contains a very important change ([#1257](https://togithub.com/chaijs/chai/issues/1257)) which will allow `jest` users to get better diffs. From this release onwards, `jest` users will be able to see which operator was used in their diffs. [The `operator` is a property of the `AssertionError` thrown when assertions fail](https://nodejs.org/api/assert.html#assert_assert_deepstrictequal_actual_expected_message). This flag indicates what kind of comparison was made.
This is also an important change for plugin maintainers. Plugin maintainers will now have access to the `operator` ` flag, which they can have access to through an `util`method called`getOperator\`.
Thanks to all the amazing people that contributed to this release.

- Allow `contain.oneOf` to take an array of possible values ([@voliva](https://togithub.com/voliva))
