- A new `--prefix` flag added into kubectl logs which prepends each log line with information about it's source (pod name and container name) ([#76471](https://github.com/kubernetes/kubernetes/pull/76471), [@m1kola](https://github.com/m1kola))

    // Pretend the comparator can compare anything. If it turns out it can't
    // compare a and b, we should get a CCE or NPE on the subsequent line. Only methods
    // that are spec'd to throw CCE and NPE should call this.

    Comparator<@Nullable Object> unsafeComparator = (Comparator<@Nullable Object>) comparator;
