I upgraded from v9.5 to v9.8 this morning without apparent issue. A project I was working on yesterday that was working fine under the previous version is now behaving oddly. The only change (other than clean project and re-compile) was changing the target SDK from 26 to 28. It is a complex project with many moving parts: MQTT client, Bluetooth printer, BT serial barcode scanner (SPP not HID), a remote display device (done via IP/Socket to another B4A app running on the remote display device). The remote display connects and displays properly. And while the barcode scanner is attempted to re-connect every couple of seconds (it is not usually on) the printer is only connected to in a print attempt which I haven't even tried yet.
Running the app in debug mode on v9.5 was decidedly slower than in release mode, but in v9.8 it is now so slow as to be unusable. At some point during the startup the app will just freeze and then eventually exit without any messages (no log messages, filtered or unfiltered). I then figured I'd try in release mode with bridgelogging enabled, and while it does run without self-terminating, I'm seeing a Bluetooth error message spammed into the unfiltered logs (I apologize for the length but I don't know what may be relevant):
The "BluetoothManagerCallback" message is repeating every half-second or less while the app is running, and I am quite confident my barcode scanner re-attempt connect is firing only every 2 seconds. Perhaps there is a dependent library that I failed to update when I updated the B4A?
