<summary>Recommended update for rust, rust1.87</summary>
<description>This update for rust, rust1.87 fixes the following issues:
Version 1.87.0 (2025-05-15)
==========================
Language
--------
- Stabilize asm_goto feature
- Allow parsing open beginning ranges (..EXPR) after unary operators !, -, and *.
- Don't require method impls for methods with Self: Sized bounds in impls for unsized types
- Stabilize feature(precise_capturing_in_traits) allowing use<...> bounds on return position impl Trait in traits
Compiler
--------
- x86: make SSE2 required for i686 targets and use it to pass SIMD types
Libraries
---------
- Stabilize the anonymous pipe API
- Add support for unbounded left/right shift operations
- Print pointer metadata in Debug impl of raw pointers
- Vec::with_capacity guarantees it allocates with the amount requested, even if Vec::capacity returns a different number.
- Most std::arch intrinsics which don't take pointer arguments can now be called from safe code if the caller has the appropriate target features already enabled
- Undeprecate env::home_dir
- Denote ControlFlow as #[must_use]
- Macros such as assert_eq! and vec! now support const {...} expressions

Cargo
-----
- Add terminal integration via ANSI OSC 9;4 sequences
- chore: bump openssl to v3
- feat(package): add --exclude-lockfile flag
Compatibility Notes
- Rust now raises an error for macro invocations inside the #![crate_name] attribute
- Unstable fields are now always considered to be inhabited
- Macro arguments of unary operators followed by open beginning ranges may now be matched differently
- Make Debug impl of raw pointers print metadata if present
- Warn against function pointers using unsupported ABI strings in dependencies
- Associated types on dyn types are no longer deduplicated
- Forbid attributes on .. inside of struct patterns (let Struct { #[attribute] .. }) =
- Make ptr_cast_add_auto_to_object lint into hard error
- Many std::arch intrinsics are now safe to call in some contexts, there may now be new unused_unsafe warnings in existing codebases.
- Limit width and precision formatting options to 16 bits on all targets
- Turn order dependent trait objects future incompat warning into a hard error
- Denote ControlFlow as #[must_use
- Windows: The standard library no longer links advapi32, except on win7. Code such as C libraries that were relying on this assumption may need to explicitly link advapi32.
- Proc macros can no longer observe expanded cfg(true) attributes.
- Start changing the internal representation of pasted tokens. Certain invalid declarative macros that were previously accepted in obscure circumstances are now correctly rejected by the compiler. Use of a tt fragment specifier can often fix these macros.
- Don't allow flattened format_args in const.
