This week's crate is cargo-asm, a cargo subcommand to show the resulting assembly of a function. Useful for performance work.
Thanks to Jay Oster for the suggestion!

Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:
No RFCs were approved last week.
Every week the team announces the 'final comment period' for RFCs and key PRs which are reaching a decision. Express your opinions now.
No RFCs are currently in the final comment period.
- [disposition: merge] Tracking issue for
- [disposition: merge] impl
- [disposition: merge] Implement PartialOrd and Ord for SocketAddr*
- [disposition: merge] Stabilize AtomicN::fetch_min and AtomicN::fetch_max
- [disposition: merge] Resolve overflow behavior for RangeFrom
- [disposition: merge] impl Step for char (make
- [disposition: merge] Stabilize core::panic::Location::caller
