That’s the case with every software updates. Upgrading just means that you jumped to the newer version. Like upgrading to the newest Firefox won’t give everyone the same benefit instantly, but its an upgrade in version nonetheless (as an analogy to Rust version).
That’s exactly the communicated meaning I was concerned an oblivious reader might get. You can use an updated Rust compiler 10 years in the future while your crate is still on 2015/2018/2021 edition. Editions are NOT software versions.
I think you misunderstand the point here. The upgrade in this case means a plus in version number, that’s what is said here. I was not implying that older versions of Rust Editions get obsolete.
