It’s very easy to number versions (e.g.,version 1, version 2, version 2.0) – it’s linear and you could place decimal points for smaller versions.
However, it’s boring. That’s why the likes of Microsoft, Android, WordPress (and a lot more) dub their versions or releases around a theme.
Let me introduce to you song titles from Gallagher Brothers’ bands (Oasis, Beady Eye, Noel Gallagher’s High Flying Birds).
But with a twist – to give it state-of-the-art, 21st century, electronic and digital age treatment (I won’t put an “e” or “i” as prefix nor remove any vowel before “r”), I will capitalize the letter of the second word found in a compound word. In case of two-word song title, I will compound them with the same capitalization (e.g., ChampagneSupernova).
HopScotch 3 is “WonderWall”.
