 - Jest’s feature `--detect-leaks` has been broken for Node 12 and newer - this has been fixed in Jest 25.
 - As announced in the blog post for Jest 24, Jest’s code base has been rewritten in TypeScript - this work was completed in Jest 24.3. So if you use any of Jest’s individual parts, you should get great IDE integration. Looking forward, we really want to make Jest mocks play nicer with type systems, and we’d love the community’s help with this. Please chime in [here](https://github.com/facebook/jest/issues/7832) with ideas and send PRs! We’ll also be investigating moving the typings for using Jest as a test runner from DefinitelyTyped into Jest itself.
 - The `jest-diff` package now exports functions like `diffLinesUnified` and `diffStringsUnified` which have configuration options, so other applications can format differences in a custom way. For more information and code examples, see its new `README.md` file in the Jest repository or on package repositories.
-- Thanks to community member [Wei An Yen](https://github.com/WeiAnAn), Jest will no longer highlight passing asymmetric matchers in expectation errors. This has been a long-standing pain point with asmmetric matchers and we're very happy it's finally solved.

 - For the second year running, Jest won the Highest Satisfaction award from [State of JS](https://2019.stateofjs.com/awards/). We are incredibly grateful for the support from the community, and hope we can build on this momentum to make 2020 even better!
