### Features
- `[@jest/core]` Instrument significant lifecycle events with [`performance.mark()`](https://nodejs.org/docs/latest-v16.x/api/perf_hooks.html#performancemarkname-options) ([#13859]((https://github.com/facebook/jest/pull/13859)))

### Fixes
- ### Fixes

- `[expect, @jest/expect]` Provide type of `actual` as a generic argument to `Matchers` to allow better-typed extensions ([#13848](https://github.com/facebook/jest/pull/13848))
- `[jest-circus]` Added explicit mention of test failing because `done()` is not being called in error message ([#13847](https://github.com/facebook/jest/pull/13847))
