I believe WSL 1 is abandonware so WSL 2 is just WSL so to answer your question, it's WSL 2 1.0.0 lol
WSL2 is much better than WSL1 at solving my problems. But that sucks it has become worse for you :/
Maybe they just shouldn't be calling it a linux system or an os but just an application server. Do that and the missing finctionality suddenly isn't a problem because it's not implied in the first place. I never would have made this complaint about tomcat or whatever.
This seems like a case where they should have picked a different naming scheme rather than numbers like WSL-A and WSL-B or something.
