Prepared by he@ in wip/rust188.
Changes:
1.88
Language
Stabilize #![feature(let_chains)] in the 2024 edition. This feature allows &&-chaining let statements inside if and while, allowing intermixture with boolean expressions. The patterns inside the let sub-expressions can be irrefutable or refutable.
Stabilize #![feature(naked_functions)]. Naked functions allow writing functions with no compiler-generated epilogue and prologue, allowing full control over the generated assembly for a particular function.
Stabilize #![feature(cfg_boolean_literals)]. This allows using boolean literals as cfg predicates, e.g. #[cfg(true)] and #[cfg(false)].
Fully de-stabilize the #[bench] attribute. Usage of #[bench] without #![feature(custom_test_frameworks)] already triggered a deny-by-default future-incompatibility lint since Rust 1.77, but will now become a hard error.
Add warn-by-default dangerous_implicit_autorefs lint against implicit autoref of raw pointer dereference. The lint will be bumped to deny-by-default in the next version of Rust.
Add invalid_null_arguments lint to prevent invalid usage of null pointers. This lint is uplifted from clippy::invalid_null_ptr_usage.
Change trait impl candidate preference for builtin impls and trivial where-clauses.
Check types of generic const parameter defaults
Compiler
Stabilize -Cdwarf-version for selecting the version of DWARF debug information to generate.
Platform Support
Demote i686-pc-windows-gnu to Tier 2.
Refer to Rust’s platform support page for more information on Rust’s tiered platform support.
Libraries
Remove backticks from #[should_panic] test failure message.
Guarantee that [T; N]::from_fn is generated in order of increasing indices., for those passing it a stateful closure.
The libtest flag --nocapture is deprecated in favor of the more consistent --no-capture flag.
Guarantee that {float}::NAN is a quiet NaN.
Stabilized APIs
Cell::update
impl Default for *const T
impl Default for *mut T
HashMap::extract_if
HashSet::extract_if
proc_macro::Span::line
proc_macro::Span::column
proc_macro::Span::start
proc_macro::Span::end
proc_macro::Span::file
proc_macro::Span::local_file
These previously stable APIs are now stable in const contexts:
NonNull<T>::replace
<*mut T>::replace
std::ptr::swap_nonoverlapping
Cell::{replace, get, get_mut, from_mut, as_slice_of_cells}
Cargo
Stabilize automatic garbage collection.
use zlib-rs for gzip compression in rust code
Rustdoc
Doctests can be ignored based on target names using ignore-* attributes.
Stabilize the --test-runtool and --test-runtool-arg CLI options to specify a program (like qemu) and its arguments to run a doctest.
Compatibility Notes
Finish 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.
Fully de-stabilize the #[bench] attribute. Usage of #[bench] without #![feature(custom_test_frameworks)] already triggered a deny-by-default future-incompatibility lint since Rust 1.77, but will now become a hard error.
Fix borrow checking some always-true patterns. The borrow checker was overly permissive in some cases, allowing programs that shouldn’t have compiled.
Update the minimum external LLVM to 19.
Make it a hard error to use a vector type with a non-Rust ABI without enabling the required target feature.
1.87
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
Platform Support
Remove i586-pc-windows-msvc target
Refer to Rust’s platform support page for more information on Rust’s tiered platform support.
Libraries

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 (rust-lang/stdarch#1714, rust-lang/stdarch#1716, rust-lang/stdarch#1717)

3. `malformed_diagnostic_attributes`: malformed attribute syntax or
options
4. `malformed_diagnostic_format_literals`: malformed format string
literal

doesn't support that, like aarch64-unknown-linux-gnu. Direct usage of
these unsupported ABI strings by declaring or defining functions was
already rejected, so this is only a change for consistency.

Doctests are now tested when cross-compiling. Just like other tests, it

## Language
- [Stabilize `#![feature(let_chains)]` in the 2024
edition.](https://redirect.github.com/rust-lang/rust/pull/132833)
This feature allows `&&`-chaining `let` statements inside `if` and
`while`, allowing intermixture with boolean expressions. The patterns
inside the `let` sub-expressions can be irrefutable or refutable.
- [Stabilize
`#![feature(naked_functions)]`.](https://redirect.github.com/rust-lang/rust/pull/134213)
Naked functions allow writing functions with no compiler-generated
epilogue and prologue, allowing full control over the generated assembly
for a particular function.
- [Stabilize
`#![feature(cfg_boolean_literals)]`.](https://redirect.github.com/rust-lang/rust/pull/138632)
This allows using boolean literals as `cfg` predicates, e.g.
`#[cfg(true)]` and `#[cfg(false)]`.
- [Fully de-stabilize the `#[bench]`
attribute](https://redirect.github.com/rust-lang/rust/pull/134273).
Usage of `#[bench]` without `#![feature(custom_test_frameworks)]`
already triggered a deny-by-default future-incompatibility lint since
Rust 1.77, but will now become a hard error.
- [Add warn-by-default `dangerous_implicit_autorefs` lint against
implicit autoref of raw pointer
dereference.](https://redirect.github.com/rust-lang/rust/pull/123239)
The lint [will be bumped to

## Compatibility Notes
- [Finish changing the internal representation of pasted
tokens](https://redirect.github.com/rust-lang/rust/pull/124141). 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.
- [Fully de-stabilize the `#[bench]`
attribute](https://redirect.github.com/rust-lang/rust/pull/134273).
Usage of `#[bench]` without `#![feature(custom_test_frameworks)]`
already triggered a deny-by-default future-incompatibility lint since
Rust 1.77, but will now become a hard error.
- [Fix borrow checking some always-true
patterns.](https://redirect.github.com/rust-lang/rust/pull/139042)
The borrow checker was overly permissive in some cases, allowing
programs that shouldn't have compiled.

## Cargo
- [When merging, replace rather than combine configuration keys that
refer to a program path and its
arguments.](https://redirect.github.com/rust-lang/cargo/pull/15066/)
- [Error if both `--package` and `--workspace` are passed but the
requested package is
missing.](https://redirect.github.com/rust-lang/cargo/pull/15071/) This
was previously silently ignored, which was considered a bug since
missing packages should be reported.
- [Deprecate the token argument in `cargo login` to avoid shell history
leaks.](https://redirect.github.com/rust-lang/cargo/pull/15057/)
- [Simplify the implementation of `SourceID`
comparisons.](https://redirect.github.com/rust-lang/cargo/pull/14980/)
This may potentially change behavior if the canonicalized URL compares
differently in alternative registries.
<a id="1.86.0-Rustdoc"></a>
## Rustdoc
- [Add a sans-serif font
setting.](https://redirect.github.com/rust-lang/rust/pull/133636)
<a id="1.86.0-Compatibility-Notes"></a>
## Compatibility Notes
- [The `wasm_c_abi` future compatibility warning is now a hard
error.](https://redirect.github.com/rust-lang/rust/pull/133951)
Users of `wasm-bindgen` should upgrade to at least version 0.2.89,
otherwise compilation will fail.
- [Remove long-deprecated no-op attributes `#![no_start]` and
`#![crate_id]`.](https://redirect.github.com/rust-lang/rust/pull/134300)
- [The future incompatibility lint `cenum_impl_drop_cast` has been made
into a hard
error.](https://redirect.github.com/rust-lang/rust/pull/135964) This
means it is now an error to cast a field-less enum to an integer if the
enum implements `Drop`.
- [SSE2 is now required for "i686" 32-bit x86 hard-float targets;
disabling it causes a warning that will become a hard error
eventually.](https://redirect.github.com/rust-lang/rust/pull/137037)
To compile for pre-SSE2 32-bit x86, use a "i586" target instead.
<a id="1.86.0-Internal-Changes"></a>
## 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.
- [Build the rustc on AArch64 Linux with ThinLTO +
PGO.](https://redirect.github.com/rust-lang/rust/pull/133807)
The ARM 64-bit compiler (AArch64) on Linux is now optimized with ThinLTO
and PGO, similar to the optimizations we have already performed for the
x86-64 compiler on Linux. This should make it up to 30% faster.
