This isn't so much a request for help, but just more of a thought mixed with a beg:
As far as I can find, this SO answer is the best documentation of all the version names that R has had since v2.14. I'm concerned that this isn't very stable solution as no one is really curating it, and I do think there should be a better way of documenting this.
There was also this blog post which had the really cool idea of adding the actual Peanuts comics being referenced, but it hasn't been updated in a few years.
Does anyone have an idea on how as a community we can do a better job preserving R's version naming?
