Upstream changes:

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/)

  (https://github.com/rust-lang/rust/pull/107941/)

Compiler
--------

  in more cases after optimization, subject to change.]

  (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)

- [`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/)

Internal Changes
----------------

These changes do not affect any public interfaces of Rust, but they represent
significant improvements to the performance or internals of rustc and related
tools.

- [Move `format_args!()` into AST (and expand it during AST lowering)]
  (https://github.com/rust-lang/rust/pull/106745/)
