I tested with the new app_python3s using:
``` def ksr_onsend_route(): KSR.dbg("onsend handling - python script\n") return 1 ```
and I see in the logs:
``` 4(16667) DEBUG: PY8 {OPTIONS}: <core> [core/kemi.c:86]: sr_kemi_core_dbg(): onsend handling - python script ```
No other error messages, all looks fine. Have you had the time for more tests?
