   Changelog:
   # What's in 1.23.0 stable

   New year, new Rust! For our first improvement today, we now avoid
   some unnecessary copies in certain situations. We've seen memory
   usage of using rustc to drop 5-10% with this change; it may be
   different with your programs.

   The documentation team has been on a long journey to move rustdoc
   to use CommonMark. Previously, rustdoc never guaranteed which
   markdown rendering engine it used, but we're finally committing to
   CommonMark. As part of this release, we render the documentation
   with our previous renderer, Hoedown, but also render it with a
   CommonMark compliant renderer, and warn if there are any differences.
   There should be a way for you to modify the syntax you use to render
   correctly under both; we're not aware of any situations where this
   is impossible. Docs team member Guillaume Gomez has written a blog
   post showing some common differences and how to solve them. In a
   future release, we will switch to using the CommonMark renderer by
   default. This warning landed in nightly in May of last year, and
   has been on by default since October of last year, so many crates
   have already fixed any issues that they've found.

   In other documentation news, historically, Cargo's docs have been
   a bit strange. Rather than being on doc.rust-lang.org, they've been
   at doc.crates.io. With this release, that's changing. You can now
   find Cargo's docs at doc.rust-lang.org/cargo. Additionally, they've
   been converted to the same format as our other long-form documentation.
   We'll be adding a redirect from doc.crates.io to this page, and
   you can expect to see more improvements and updates to Cargo's docs
   throughout the year.

   See the detailed release notes for more.

   ## Library stabilizations

   As of Rust 1.0, a trait named AsciiExt existed to provide ASCII
   related functionality on u8, char, [u8], and str. To use it, you'd
   write code like this:

   use std::ascii::AsciiExt;

   let ascii = 'a';
   let non_ascii = '❤';
   let int_ascii = 97;

   assert!(ascii.is_ascii());
   assert!(!non_ascii.is_ascii());
   assert!(int_ascii.is_ascii());

   In Rust 1.23, these methods are now defined directly on those types,
   and so you no longer need to import the trait. Thanks to our
   stability guarantees, this trait still exists, so if you'd like to
   still support Rust versions before Rust 1.23, you can do this:

   #[allow(unused_imports)]
   use std::ascii::AsciiExt;

   ...to suppress the related warning. Once you drop support for older
   Rusts, you can remove both lines, and everything will continue to
   work.

   Additionally, a few new APIs were stabilized this release:

       The various std::sync::atomic types now implement From their
       non-atomic types. For example, let x = AtomicBool::from(true);.
       () now implements FromIterator<()>; check the PR for a neat
       use-case.  RwLock<T> has had its Send restriction lifted

   See the detailed release notes for more.

   ## Cargo features

   cargo check can now check your unit tests.

   cargo uninstall can now uninstall more than one package in one
   command.
