My current best guess is that when they selected the change-set to support Bluetooth, they unintentional dropped the package type blocking change-set.
So KT3 (and KOA2) only for 5.8.10
It will be interesting to learn what happens to 5.8.11

There have been times in the past when it seemed like the Keystone Cops are running Lab126.
Don't let your new KOA2 be caught by an unintended OTA update until you are sure you are ready for it.
