Don't include current rustc version string in feature removed help The version string is difficult to properly normalize out, and removing it isn't a huge deal (the user can query version info easily through `rustc --version` or `cargo --version`). The normalization options were all non-ideal (see https://github.com/rust-lang/rust/pull/142940#issuecomment-2998518450): - Per-test version string normalization is nasty to maintain, and we need to maintain `n` copies of it. See rust-lang/rust#142930 where the regex wasn't robust against different release channels. - Centralized compiletest normalization (with a directive opt-out) is also not ideal, because `cfg(version(..))` tests can't have those accidentally normalized out (and you'd have to remember to opt-out). r? `@workingjubilee` (discussed in rust-lang/rust#142940)
