     Clippy has a number of exciting new lints: https://github.com/rust-lang/rust-clippy/blob/master/CHANGELOG.md#new-lints

     For example, you can now enable #![warn(clippy::manual_let_else)] to tell you about some situations where you could use the recently introduced let-else syntax.

     The integer types now have (integer) logarithm methods: ilog, ilog10, ilog2. (And zero-checking versions: checked_ilog, checked_ilog10, and checked_ilog2.)

     ilog2 is implemented using leading_zeros(), so is very efficient.

     All of these methods usable in const context too.

     std::sync::mpsc has a new implementation, based on crossbeam-channel.

     The old implementation had some issues and was hard to maintain. The new implementation fixes some small but long-standing bugs and has better performance.

     (The public interface remains unchanged.)

     A must_use attribute on async functions now does what you expect.

     #[must_use]
     async fn hey() -> Thing { … }

     Now, #[must_use] applies to `Thing`, instead of to the `impl Future<Output=Thing>` (which wasn't very useful).
