This one comes to mind after seeing this question.
Historically almost every bump of Android API version warrants a new tag, but when Android 4.0.3 dawned as a "minor" version of Android 4.0 but comes with API15 instead of API14, there's no designated tag for it. I assume this is because that the lifespan of API14 is too short (2 months) to be of use to discussion, thus 4.0-ice-cream-sandwich remains.
Now, minus the preview period, Android 7.0 (API24) has a lifespan even shorter than that of API14, then gave way to Android 7.1 (API25). In this sense Android 7.1 is definitely the way to go in future discussions. Should we create this tag and make 7.0-nougat a synonym to it, or the other way round?
