For me, life’s too short to get worked up over tiny changes to the AirPods Pro firmware. They’re earbuds, not essential productivity software where knowing what changed can be essential for work. While I always prefer detailed release notes, speaking as someone who reads a LOT of them from a wide range of developers, the vast majority aren’t in the slightest bit useful or interesting. And that’s with software where you can actually see what’s happening, not firmware embedded in a tiny pair of earbuds. I have no problem assuming these changes are ones that few, if any, will notice. And without having noticed anything, I don’t care when the update installs.
In fact, the update seems to fix problems that some people had with disconnects.
