openHAB 3.4 Milestone discussion

Since my upgrade from M3 to M4 the systeminfo binding does not work anymore.
The thing is uninitialized with a HANDLER_MISSING_ERROR.

With M3 the binding reports:

2022-11-07 22:10:30.286 [DEBUG] [o.internal.handler.SysteminfoHandler] - Systeminfo implementation is instantiated!

2022-11-07 22:10:30.493 [DEBUG] [o.internal.handler.SysteminfoHandler] - Schedule one time update for low priority tasks.

With M4 it looks different:

These messages are new, not sure if related and where to look for the reason.
