Fixed
- Fixed maintenance services logging failures during shutdown or leadership loss when a driver returned a socket or SQL error instead of the cancellation reason. Genuine query timeouts and database failures are still reported. PR #1577.
- Fixed a cancelled job that was retried being cancelled again when the client checked for cancellation requests, which it does while polling and after its notification stream reconnects. Retrying a job now clears its earlier attempt's cancellation request, like River for Go. PR #1564.
