I just (finally) upgraded to Catalina last week and the 8.10.2 bindist works just fine (you have to fiddle with xattr after unzipping, there's an issue on gitlab that has the right command in there). If you're going to Mojave then there's 0 issues. Big Sur I haven't tried yet.

I didn't notice any performance regressions, but I also haven't paid close attention.
