I'm indeed excited about those! There have been releases where ARM (maybe I was using armv7 rather than aarch64 then, but I'm on aarch64 now) was totally broken, and now I know that won't happen on 1.49 or beyond. Min const generics...I'm not sure I'll find much use for it until const_evaluatable_checked happens, but I'm glad to see progress. Stable backtraces will mean I can stop using the deprecated failure crate without giving up my quality diagnostics.
