iTunes 12.8 work w/original Airplay v1 devices?
I'm about to upgrade to iTunes 12.8 on my iMac BUT wonder if my older Airplay v1 devices will still be able to receive streaming audio. I have an older Airport express hooked up to an outdoor stereo, Apple TV 3 for receiving/outputting digital audio on my main entertainment system and an JBL Airplay speaker. I'm concerned that if I upgrade I'll lose streaming ability to all these devices. Thanks for any advice.
iMac (21.5-inch, Late 2013), macOS High Sierra (10.13.5), LOTS of Apple devices
