 ### Features
 
+- `[jest-runtime]` Support `import.meta.filename` and `import.meta.dirname` (available from [Node 20.11](https://nodejs.org/en/blog/release/v20.11.0))
 - `[jest-circus, jest-cli, jest-config]` Add `waitNextEventLoopTurnForUnhandledRejectionEvents` flag to minimise performance impact of correct detection of unhandled promise rejections introduced in [#14315](https://github.com/jestjs/jest/pull/14315) ([#14681](https://github.com/jestjs/jest/pull/14681))
 - `[jest-circus]` Add a `waitBeforeRetry` option to `jest.retryTimes` ([#14738](https://github.com/jestjs/jest/pull/14738))
 - `[jest-circus, jest-jasmine2]` Allow `setupFilesAfterEnv` to export an async function ([#10962](https://github.com/jestjs/jest/issues/10962))
