Why would I update all the time? There is no easy way to go back, and I never encountered an appleTV update which improved performance. Since the original. I use the my Apple TV device to stream. Apple always wants more. The “last” updates on older devices always the worst. Once fine, they struggle to run. Oh, time to throw it out. Legacy support? Oh too expensive… Open the hardware for devices out of support…Oh wee can’t do that. Most of us are stuck to some degree in the “ecosystem” in 2023. Where is the “focus” upgrade to have apple leave us alone, till we feel like risking an upgrade?
Security updates are a good thing
New stuff is always being rolled out. New revised codecs, changes to networking, support for new and improved technologies.
Improved code, fixes to issues (we all know software issues are part and parcel with modern life).
New features, like new HomeKit stuff, FaceTime, and more.
