Rust 1.21
For those curious about getting involved with Rust, note that right now is an ideal time. :) This last quarter of the year is reserved for "the impl period", a collection of all-out heads-down sprints designed to make sure that none of the remaining milestones from our 2017 roadmap get left behind. There are currently 37 working groups in a variety of disciplines, some more involved than others and some more popular than others, but mentorship is offered to all who'd like to contribute!See our most recent newsletter for the impl period here: https://internals.rust-lang.org/t/the-impl-period-newsletter...
