Yes. I start the updates withing 10 minutes of finding that they've been released. Always.
I'm pretty sure that hciconfig is just a tool to identify the bluetooth module that's installed on a device. As such, and especially if it's been deprecated, it's not of much interest to me. But I'll be very pleased if it turns out that I can use my earbuds again after another update or two.
EDIT: That "important fix" in the bluez package was what probably broke it for me. The timing is about right.
Hoping for a quick fix.
