Version 1.87.0 (2025-05-15)
==========================

Language
--------
- [Stabilize `asm_goto` feature](https://github.com/rust-lang/rust/pull/133870)
- [Allow parsing open beginning ranges (`..EXPR`) after unary operators `!`, `-`, and `*`](https://github.com/rust-lang/rust/pull/134900).
- [Don't require method impls for methods with `Self: Sized` bounds in `impl`s for unsized types](https://github.com/rust-lang/rust/pull/135480)
- [Stabilize `feature(precise_capturing_in_traits)` allowing `use<...>` bounds on return position `impl Trait` in `trait`s](https://github.com/rust-lang/rust/pull/138128)


Compiler
--------
- [x86: make SSE2 required for i686 targets and use it to pass SIMD types](https://github.com/rust-lang/rust/pull/135408)


Platform Support
- [Remove `i586-pc-windows-msvc` target](https://github.com/rust-lang/rust/pull/137957)

Libraries
---------
- [Stabilize the anonymous pipe API](https://github.com/rust-lang/rust/issues/127154)

Cargo
-----
- [Add terminal integration via ANSI OSC 9;4 sequences](https://github.com/rust-lang/cargo/pull/14615/)
- [chore: bump openssl to v3](https://github.com/rust-lang/cargo/pull/15232/)
- [feat(package): add --exclude-lockfile flag](https://github.com/rust-lang/cargo/pull/15234/)


Compatibility Notes
- [Rust now raises an error for macro invocations inside the `#![crate_name]` attribute](https://github.com/rust-lang/rust/pull/127581)
- [Unstable fields are now always considered to be inhabited](https://github.com/rust-lang/rust/pull/133889)
- [Macro arguments of unary operators followed by open beginning ranges may now be matched differently](https://github.com/rust-lang/rust/pull/134900)
- [Make `Debug` impl of raw pointers print metadata if present](https://github.com/rust-lang/rust/pull/135080)
- [Warn against function pointers using unsupported ABI strings in dependencies](https://github.com/rust-lang/rust/pull/135767)
- [Associated types on `dyn` types are no longer deduplicated](https://github.com/rust-lang/rust/pull/136458)
- [Forbid attributes on `..` inside of struct patterns (`let Struct { #[attribute] .. }) =`](https://github.com/rust-lang/rust/pull/136490)
- [Make `ptr_cast_add_auto_to_object` lint into hard error](https://github.com/rust-lang/rust/pull/136764)
- 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](https://github.com/rust-lang/rust/pull/136932)
- [Turn order dependent trait objects future incompat warning into a hard error](https://github.com/rust-lang/rust/pull/136968)
- [Denote `ControlFlow` as `#[must_use]`](https://github.com/rust-lang/rust/pull/137449)
- [Windows: The standard library no longer links `advapi32`, except on win7.](https://github.com/rust-lang/rust/pull/138233) 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.](https://github.com/rust-lang/rust/pull/138844)
- [Start changing the internal representation of pasted tokens](https://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.
- [Don't allow flattened format_args in const.](https://github.com/rust-lang/rust/pull/139624)


Internal Changes
