There is some code optimisation for iPhone 7 and 8, possibly. IPSW used to be 4.01 GB and now it is 4.00 GB. Minor, but I'm interested to know what might have happened and if that brings any noticeable positive improvement to these devices.

Every build will be slightly different in size due to code and asset changes.

Yes. I noticed that the last few releases for iPhone 7/ 8 have all been 4.01 GB but this one is 0.01 GB less so caught my eye and I wonder if changes produce a noticeable impact. 10 MB reduction ought to make something better! :D

Every time I change the eSim / sim label name under cellular it eventually changes back to primary and secondary. My secondary is a physical sim.

this has been happening since iOS 13. Rather annoying, sent bug to Apple and of course nothing.

anyone else notice this?

Code optimization for performance typically produces larger binaries, not smaller. Removing dead/unused code will lead to smaller binaries.

It appears I might have used the term 'code optimisation' loosely? I meant to say dead/ unused code might have been removed. Is that not optimisation?
