Does Instapaper still support iOS 3.1.3?
Today: Yes. In the near future: No. There are a number of great features that I want to use in iOS 4 and 5, and compatibility with iOS 3.1.3 is starting to become an expensive burden. My code is quickly filling with special cases and duplicate implementations, and this will hinder Instapaper’s feature development, maintenance, and stability until I can eliminate 3.1.3 compatibility. My quality assurance would also improve since my testing-device count would be greatly reduced. So in one of the next releases, I’m raising the minimum to iOS 4.0. This will drop compatibility for the original iPhone and first-generation iPod Touch, all of which are now at least three years old and represent only 0.48% of Instapaper’s customers. And in the not-too-distant future, possibly as soon as next spring, I intend to raise the minimum to iOS 5 because it has tons of great UIKit improvements and opportunities for me to delete lots of hacky legacy code. iOS 5 excludes the iPhone 3G and second-generatio
