Not many changes have got in since the last release but this one contains a very important change (#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. 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 operatorflag, which they can have access to through anutilmethod calledgetOperator`.
Thanks to all the amazing people that contributed to this release.
