-### v1.19.1
-
-  - Fix `Process.waitall` / `Process.detach` under the `URing` selector: when `io_uring`'s `waitid` reported an error (e.g. `ECHILD` when there are no more children), the `process_wait` hook raised instead of returning the error as a `Process::Status`, so callers that expect `waitpid` to *report* "no more children" rather than raise would fail.
