  <summary>Recommended update for rust, rust1.67</summary>
  <description>This update for rust, rust1.67 fixes the following issues:

Rust is shipped in version 1.67.0.

Changes in rust1.67:

Version 1.67.0 (2023-01-26)
==========================

Language
--------

- Make `Sized` predicates coinductive, allowing cycles.
- #[must_use]` annotations on `async fn` also affect the `Future::Output`.
- Elaborate supertrait obligations when deducing closure signatures.
- Invalid literals are no longer an error under `cfg(FALSE)`.
- Unreserve braced enum variants in value namespace.

Compiler
--------

- Enable varargs support for calling conventions other than `C` or `cdecl`.
- Add new MIR constant propagation based on dataflow analysis.
- Optimize field ordering by grouping m\*2^n-sized fields with equivalently aligned ones.
- Stabilize native library modifier `verbatim`.

Added and removed targets:

- Remove tier 3 `linuxkernel` targets
  Refer to Rust's platform support page for more information on Rust's tiered platform support.

Libraries
---------

- Merge `crossbeam-channel` into `std::sync::mpsc`.
- Fix inconsistent rounding of 0.5 when formatted to 0 decimal places.
- Derive `Eq` and `Hash` for `ControlFlow`.
- Don't build `compiler_builtins` with `-C panic=abort`.

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

- {integer}::checked_ilog
- {integer}::checked_ilog2
- {integer}::checked_ilog10
- {integer}::ilog
- {integer}::ilog2
- {integer}::ilog10
- NonZeroU*::ilog2
- NonZeroU*::ilog10
- NonZero*::BITS

These APIs are now stable in const contexts:

- char::from_u32
- char::from_digit
- char::to_digit
- core::char::from_u32
- core::char::from_digit

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

- The layout of `repr(Rust)` types now groups m\*2^n-sized fields with
  equivalently aligned ones.
  This is intended to be an optimization, but it is also known to increase type
  sizes in a few cases for the placement of enum tags. As a reminder, the layout
  of `repr(Rust)` types is an implementation detail, subject to change.
- 0.5 now rounds to 0 when formatted to 0 decimal places.
  This makes it consistent with the rest of floating point formatting that
  rounds ties toward even digits.
- Chains of `&amp;&amp;` and `||` will now drop temporaries from their sub-expressions in
  evaluation order, left-to-right.
  Previously, it was "twisted" such that the _first_ expression dropped its
  temporaries _last_, after all of the other expressions dropped in order.
- Underscore suffixes on string literals are now a hard error.
  This has been a future-compatibility warning since 1.20.0.
- Stop passing `-export-dynamic` to `wasm-ld`.
- main` is now mangled as `__main_void` on `wasm32-wasi`.
- Cargo now emits an error if there are multiple registries in the configuration
   with the same index URL.
