This isn't really true though. Rust has integrated versioning and it cordons things off between editions. If you're within the same edition, you get updates without breaking changes. Even if you aren't in the same edition, you can grab specific compiler versions. Granted, in these circumstances you won't get security updates, but you have to be very out of date for that to be a problem.
I wrote an app using brand new Rust features for work 2 years ago. Despite upgrading the compiler version several times, I never needed to make a single code change. It is still being used daily as well.
Just checked it out, this thing looks sick. But it also looks ugly as shit. Is it as ugly as it looks in person? Specifically not a fan of the RGB LED ring thing on the back?
