I first thought it was some kind of extrapolation like... at the rate features are currently being added, Markdown will land in ~2032 with iOS 26... just noticed about the new version numbering, I missed that news!
(Wait, I am.)
It’s a silly game to play. Firefox did something similar. Their versioning moved famously slow, then all the sudden they started releasing major versions every other week until their version numbering was compatible to Chrome’s version.
