Version 1.69.0 (2023-04-20)
==========================

Language
--------

- [Deriving built-in traits on packed structs works with `Copy` fields.](https://github.com/rust-lang/rust/pull/104429/)
- [Stabilize the `cmpxchg16b` target feature on x86 and x86_64.](https://github.com/rust-lang/rust/pull/106774/)
- [Improve analysis of trait bounds for associated types.](https://github.com/rust-lang/rust/pull/103695/)
- [Allow associated types to be used as union fields.](https://github.com/rust-lang/rust/pull/106938/)
- [Allow `Self: Autotrait` bounds on dyn-safe trait methods.](https://github.com/rust-lang/rust/pull/107082/)
- [Treat `str` as containing `[u8]` for auto trait purposes.](https://github.com/rust-lang/rust/pull/107941/)

Compiler
--------

- [Upgrade `*-pc-windows-gnu` on CI to mingw-w64 v10 and GCC 12.2.](https://github.com/rust-lang/rust/pull/100178/)
- [Rework min_choice algorithm of member constraints.](https://github.com/rust-lang/rust/pull/105300/)
- [Support `true` and `false` as boolean flags in compiler arguments.](https://github.com/rust-lang/rust/pull/107043/)
- [Default `repr(C)` enums to `c_int` size.](https://github.com/rust-lang/rust/pull/107592/)

Libraries
---------

- [Implement the unstable `DispatchFromDyn` for cell types, allowing downstream experimentation with custom method receivers.](https://github.com/rust-lang/rust/pull/97373/)
- [Document that `fmt::Arguments::as_str()` may return `Some(_)` in more cases after optimization, subject to change.](https://github.com/rust-lang/rust/pull/106823/)
- [Implement `AsFd` and `AsRawFd` for `Rc`.](https://github.com/rust-lang/rust/pull/107317/)

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

- [`CStr::from_bytes_until_nul`](https://doc.rust-lang.org/stable/core/ffi/struct.CStr.html#method.from_bytes_until_nul)
- [`core::ffi::FromBytesUntilNulError`](https://doc.rust-lang.org/stable/core/ffi/struct.FromBytesUntilNulError.html)

These APIs are now stable in const contexts:

- [`SocketAddr::new`](https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.new)
- [`SocketAddr::ip`](https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.ip)
- [`SocketAddr::port`](https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.port)
- [`SocketAddr::is_ipv4`](https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.is_ipv4)
- [`SocketAddr::is_ipv6`](https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.is_ipv6)
- [`SocketAddrV4::new`](https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV4.html#method.new)
- [`SocketAddrV4::ip`](https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV4.html#method.ip)
- [`SocketAddrV4::port`](https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV4.html#method.port)
- [`SocketAddrV6::new`](https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV6.html#method.new)
- [`SocketAddrV6::ip`](https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV6.html#method.ip)
- [`SocketAddrV6::port`](https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV6.html#method.port)
- [`SocketAddrV6::flowinfo`](https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV6.html#method.flowinfo)
- [`SocketAddrV6::scope_id`](https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV6.html#method.scope_id)

Cargo
-----

- [Cargo now suggests `cargo fix` or `cargo clippy --fix` when compilation warnings are auto-fixable.](https://github.com/rust-lang/cargo/pull/11558/)
- [Cargo now suggests `cargo add` if you try to install a library crate.](https://github.com/rust-lang/cargo/pull/11410/)
- [Cargo now sets the `CARGO_BIN_NAME` environment variable also for binary examples.](https://github.com/rust-lang/cargo/pull/11705/)

Rustdoc
-----

- [Vertically compact trait bound formatting.](https://github.com/rust-lang/rust/pull/102842/)
- [Only include stable lints in `rustdoc::all` group.](https://github.com/rust-lang/rust/pull/106316/)
- [Compute maximum Levenshtein distance based on the query.](https://github.com/rust-lang/rust/pull/107141/)
- [Remove inconsistently-present sidebar tooltips.](https://github.com/rust-lang/rust/pull/107490/)
- [Search by macro when query ends with `!`.](https://github.com/rust-lang/rust/pull/108143/)

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

- [The `rust-analysis` component from `rustup` now only contains a warning placeholder.](https://github.com/rust-lang/rust/pull/101841/) This was primarily intended for RLS, and the corresponding `-Zsave-analysis` flag has been removed from the compiler as well.
- [Unaligned references to packed fields are now a hard error.](https://github.com/rust-lang/rust/pull/102513/) This has been a warning since 1.53, and denied by default with a future-compatibility warning since 1.62.
- [Update the minimum external LLVM to 14.](https://github.com/rust-lang/rust/pull/107573/)
- [Cargo now emits errors on invalid characters in a registry token.](https://github.com/rust-lang/cargo/pull/11600/)
- [When `default-features` is set to false of a workspace dependency, and an inherited dependency of a member has `default-features = true`, Cargo will enable default features of that dependency.](https://github.com/rust-lang/cargo/pull/11409/)
- [Cargo denies `CARGO_HOME` in the `[env]` configuration table. Cargo itself doesn't pick up this value, but recursive calls to cargo would, which was not intended.](https://github.com/rust-lang/cargo/pull/11644/)
- [Debuginfo for build dependencies is now off if not explicitly set. This is expected to improve the overall build time.](https://github.com/rust-lang/cargo/pull/11252/)
