I always wondered what’s keeping packages back from having wheels ready the day a release drops, or way before even?
I imagine often it’s just another parameter in a CI somewhere, where things mostly “just work” because backward-incompatible breakages have become much rarer.
It's usually a question of having the resources (usually developers to debug issues). IIRC pretty much all Windows wheels are maintained by one guy, Christoph Gohlke, he was a godsend when I worked on a Windows laptop. I owe that guy many beers.
I've never seen a better illustration of xkcd 2347 than Christoph Gohlke. I tried to find a donation link to send him small thank yous but couldn't find one.
