On September 16, 2020, Apple released version 14 of both iOS and iPadOS, along with updated versions of tvOS and watch OS. Today, Information Systems & Computing (ISC) approved iOS and iPadOS 14.0.1 for general use.
ISC and other Penn constituents have tested iOS 14 and iPadOS 14 extensively. They have not discovered any compatibility issues with various University systems and many current University apps, including the apps and services listed here:

Microsoft released the first Surface Go tablet in August 2018. Its small size, 1.15-pound weight, and relatively low price were of interest to many at the University. ISC testing revealed that the Surface Go's low-end Intel Pentium Gold 4415Y processor made it relatively slow in an era when almost all new tablets and notebooks are fast. This slowness would typically have disqualified it from significant interest at the University.

With the advent of macOS 10.15 Catalina (expected to release sometime in early fall 2019), Apple will be removing support for all 32-bit applications. Apple has been warning about this for a few years now and has gotten increasingly aggressive at informing users who run macOS 10.14 Mojave that they have dated applications that won't work in the future.

This blog entry will detail one person's efforts to clean his system of 32-bit applications (or at least become aware of the applications that will be an issue).
