If you noticed that there aren’t many major changes that have been spotted in the iOS 12.3 beta, it’s because the next software update is looking fairly incremental. Besides the additional support for new Apple services, iOS 12.3 will likely be a fairly minor update that primarily introduces under-the-hood changes and tweaks.
For example, the Wallet transaction history was slightly tweaked in beta 2 and an Accessibility bug was patched in beta 3. But while new additions to iOS 12.3 have been fairly sparse over the past few betas, it’s likely that Apple will continue to refine the features it has added. We expect Apple to continue adding smaller features until the final version of iOS 12.3 is released sometime in May.
