 - **A refreshed Docker Runner**: to support new languages better and fix concurrency issues, we [rewrote the Docker Runner](https://github.com/testground/testground/pull/1407#issuecomment-1203853804). In our tests, **false negatives went from 40% to <1%.**
 - **Benchmarking and stability improvements:** we've implemented tooling and [fixes](https://github.com/testground/testground/pull/1421) that help with CI [testing](https://github.com/libp2p/test-plans/pulls?q=is%3Apr+is%3Amerged+merged%3A%3E%3D2022-01-01). Some of this work will soon become part of the Testground Stability Dashboard and custom CI actions.
