I also wanted to followup on a suggestion for change in recommended testing strategy; [pre-release testing strategy · Issue #16 · rust-lang/release-team · GitHub](https://github.com/rust-lang/release-team/issues/16) is now tracking that discussion, so please engage there if you have opinions. Thanks!
