Apple today rolled out the iOS/iPadOS 18.5 Developer Preview Beta 2 update (internal version number: 22F5053f) to iPhone and iPad users, 12 days after the last Beta/RC release.
For now, iOS 18.5 and iPadOS 18.5 are relatively minor updates that introduce only a few new design changes, provide more options for restoring the mail app to its previous design, including removing contact photos, and make AppleCare information easier to find.
