We will look at the difference between Options and Transients, in what situations plugin developers should use one over the other, and why one is not superior to the other. We will will also explore how Theme Mods fit in there and how they could change your theme development approach. This will lead us to dive into the concept of “notoptions” in WordPress, and — if we have time left — Site Options, User Options, and User Settings.
