Stabilized APIs
---------------

- [`impl<T: Send> Sync for mpsc::Sender<T>`](https://doc.rust-lang.org/stable/std/sync/mpsc/struct.Sender.html#impl-Sync-for-Sender%3CT%3E)
- [`impl TryFrom<&OsStr> for &str`](https://doc.rust-lang.org/stable/std/primitive.str.html#impl-TryFrom%3C%26'a+OsStr%3E-for-%26'a+str)
- [`String::leak`](https://doc.rust-lang.org/stable/alloc/string/struct.String.html#method.leak)

These APIs are now stable in const contexts:

- [`CStr::from_bytes_with_nul`](https://doc.rust-lang.org/stable/std/ffi/struct.CStr.html#method.from_bytes_with_nul)
- [`CStr::to_bytes`](https://doc.rust-lang.org/stable/std/ffi/struct.CStr.html#method.to_bytes)
- [`CStr::to_bytes_with_nul`](https://doc.rust-lang.org/stable/std/ffi/struct.CStr.html#method.to_bytes_with_nul)
- [`CStr::to_str`](https://doc.rust-lang.org/stable/std/ffi/struct.CStr.html#method.to_str)

Cargo
-----

- Enable `-Zdoctest-in-workspace` by default. When running each documentation
  test, the working directory is set to the root directory of the package the
  test belongs to.
  [docs](https://doc.rust-lang.org/nightly/cargo/commands/cargo-test.html#working-directory-of-tests)
  [#12221](https://github.com/rust-lang/cargo/pull/12221)
  [#12288](https://github.com/rust-lang/cargo/pull/12288)
- Add support of the "default" keyword to reset previously set `build.jobs`
  parallelism back to the default.

Compatibility Notes
-------------------

- [Alter `Display` for `Ipv6Addr` for IPv4-compatible addresses](https://github.com/rust-lang/rust/pull/112606/)
- Cargo changed feature name validation check to a hard error. The warning was
  added in Rust 1.49. These extended characters aren't allowed on crates.io, so
  this should only impact users of other registries, or people who don't publish
  to a registry.
