1.87.0 May 15, 2025 New Release 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:
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 (rust-lang/stdarch#1714, rust-lang/stdarch#1716, rust-lang/stdarch#1717)
Undeprecate env::home_dir
Denote ControlFlow as #[must_use]
Macros such as assert_eq! and vec! now support const {...} expressions

1.86.0 Apr 13, 2025 New Release Language:
Stabilize upcasting trait objects to supertraits.
Allow safe functions to be marked with the #[target_feature] attribute.
The missing_abi lint now warns-by-default.
Rust now lints about double negations, to catch cases that might have intended to be a prefix decrement operator (--x) as written in other languages. This was previously a clippy lint, clippy::double_neg, and is now available directly in Rust as double_negations.
More pointers are now detected as definitely not-null based on their alignment in const eval.
Empty repr() attribute applied to invalid items are now correctly rejected.
Inner attributes #![test] and #![rustfmt::skip] are no longer accepted in more places than intended.
Compiler:
Debug-assert that raw pointers are non-null on access.
Change -O to mean -C opt-level=3 instead of -C opt-level=2 to match Cargo's defaults.
Fix emission of overflowing_literals under certain macro environments.
Platform Support:
Replace i686-unknown-redox target with i586-unknown-redox.
Increase baseline CPU of i686-unknown-hurd-gnu to Pentium 4.
New tier 3 targets:
{aarch64-unknown,x86_64-pc}-nto-qnx710_iosock. For supporting Neutrino QNX 7.1 with io-socket network stack.
{aarch64-unknown,x86_64-pc}-nto-qnx800. For supporting Neutrino QNX 8.0 (no_std-only).
{x86_64,i686}-win7-windows-gnu. Intended for backwards compatibility with Windows 7. {x86_64,i686}-win7-windows-msvc are the Windows MSVC counterparts that already exist as Tier 3 targets.
amdgcn-amd-amdhsa.
x86_64-pc-cygwin.
{mips,mipsel}-mti-none-elf. Initial bare-metal support.
m68k-unknown-none-elf.
armv7a-nuttx-{eabi,eabihf}, aarch64-unknown-nuttx, and thumbv7a-nuttx-{eabi,eabihf}.
Refer to Rust's platform support page for more information on Rust's tiered platform support.
Libraries:
The type of FromBytesWithNulError in CStr::from_bytes_with_nul(bytes: &[u8]) -> Result<&Self, FromBytesWithNulError> was changed from an opaque struct to an enum, allowing users to examine why the conversion fa
1.85.1 Mar 18, 2025 New Release Language:
Stabilize &mut, *mut, &Cell, and *const Cell in const.
Allow creating references to statics in const initializers.
Implement raw lifetimes and labels ('r#ident).
Define behavior when atomic and non-atomic reads race.
Non-exhaustive structs may now be empty.
Disallow implicit coercions from places of type !
const extern functions can now be defined for other calling conventions.
Stabilize expr_2021 macro fragment specifier in all editions.
The non_local_definitions lint now fires on less code and warns by default.
Compiler:
Deprecate unsound -Csoft-float flag.
Add many new tier 3 targets:
aarch64_unknown_nto_qnx700
arm64e-apple-tvos
armv7-rtems-eabihf
loongarch64-unknown-linux-ohos
riscv32-wrs-vxworks and riscv64-wrs-vxworks
riscv32{e|em|emc}-unknown-none-elf
x86_64-unknown-hurd-gnu
x86_64-unknown-trusty
Refer to Rust's platform support page for more information on Rust's tiered platform support.
Libraries:
Implement PartialEq for ExitCode.
Document that catch_unwind can deal with foreign exceptions without UB, although the exact behavior is unspecified.
Implement Default for HashMap/HashSet iterators that don't already have it.
Bump Unicode to version 16.0.0.
Change documentation of ptr::add/sub to not claim equivalence with offset..
