I mean... Why would it be compatible with 1.x if 2 wasn't? There is an upgrade guide to upgrade from 1 to 2 and later. 3 has been out for a long time. Not sure

  IME most projects use semver to indicate possibly breaking changes that might require a manual fix or three, not a whole different project that requires 100% changes across the board and starting over from scratch. Even node itself doesn't just kill your projects with every major version. Judging by the other comments in this thread, and the blog post saying that "zero-install is disabled by default", I had kinda hoped 4 would be a reboot of Yarn v1 with modern conveniences. This does not appear to be the case. I'm still not sure whether it goes like "2.x -> 3.x -> 4.x are all in the same line, and upgrading from 2 to anything beyond that is easy" or if they are each as different from each other as 2 was from 1. That's the confusing part. (Like, did the 2.x line stabilize into 4.x, or are these just four separate projects altogether?) I think it would've been a lot clearer if they just named Yarn 2+ something entirely different, like Moment did with Luxon
