Version 1.71.0 (2023-07-13)
==========================

Language
--------

- [Stabilize `raw-dylib`, `link_ordinal`, `import_name_type` and `-Cdlltool`.](https://github.com/rust-lang/rust/pull/109677/)
- [Uplift `clippy::{drop,forget}_{ref,copy}` lints.](https://github.com/rust-lang/rust/pull/109732/)
- [Type inference is more conservative around constrained vars.](https://github.com/rust-lang/rust/pull/110100/)
- [Use fulfillment to check `Drop` impl compatibility](https://github.com/rust-lang/rust/pull/110577/)

Compiler
--------

- [Evaluate place expression in `PlaceMention`](https://github.com/rust-lang/rust/pull/104844/),
  making `let _ =` patterns more consistent with respect to the borrow checker.
- [Add `--print deployment-target` flag for Apple targets.](https://github.com/rust-lang/rust/pull/105354/)
- [Stabilize `extern "C-unwind"` and friends.](https://github.com/rust-lang/rust/pull/106075/)
  The existing `extern "C"` etc. may change behavior for cross-language unwinding in a future release.
- [Update the version of musl used on `*-linux-musl` targets to 1.2.3](https://github.com/rust-lang/rust/pull/107129/),
  enabling [time64](https://musl.libc.org/time64.html) on 32-bit systems.
- [Stabilize `debugger_visualizer`](https://github.com/rust-lang/rust/pull/108668/)
  for embedding metadata like Microsoft's Natvis.
- [Enable flatten-format-args by default.](https://github.com/rust-lang/rust/pull/109999/)
- [Make `Self` respect tuple constructor privacy.](https://github.com/rust-lang/rust/pull/111245/)
- [Improve niche placement by trying two strategies and picking the better result.](https://github.com/rust-lang/rust/pull/108106/)
- [Use `apple-m1` as the target CPU for `aarch64-apple-darwin`.](https://github.com/rust-lang/rust/pull/109899/)
- [Add Tier 3 support for the `x86_64h-apple-darwin` target.](https://github.com/rust-lang/rust/pull/108795/)
- [Promote `loongarch64-unknown-linux-gnu` to Tier 2 with host tools.](https://github.com/rust-lang/rust/pull/110936/)

Refer to Rust's [platform support page][platform-support-doc]
for more information on Rust's tiered platform support.

Libraries
---------
- [Rework handling of recursive panics.](https://github.com/rust-lang/rust/pull/110975/)
  Additional panics are allowed while unwinding, as long as they are caught before escaping
  a `Drop` implementation, but panicking within a panic hook is now an immediate abort.
- [Loosen `From<&[T]> for Box<[T]>` bound to `T: Clone`.](https://github.com/rust-lang/rust/pull/103406/)
- [Remove unnecessary `T: Send` bound](https://github.com/rust-lang/rust/pull/111134/)
  in `Error for mpsc::SendError<T>` and `TrySendError<T>`.
- [Fix docs for `alloc::realloc`](https://github.com/rust-lang/rust/pull/108630/)
  to match `Layout` requirements that the size must not exceed `isize::MAX`.
- [Document `const {}` syntax for `std::thread_local`.](https://github.com/rust-lang/rust/pull/110620/)
  This syntax was stabilized in Rust 1.59, but not previously mentioned in release notes.

- [Support strikethrough with single tildes.](https://github.com/rust-lang/rust/pull/111152/) (`~~old~~` vs. `~new~`)

Misc
----

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

- [Remove structural match from `TypeId`.](https://github.com/rust-lang/rust/pull/103291/)
  Code that uses a constant `TypeId` in a pattern will potentially be broken.
  Known cases have already been fixed -- in particular, users of the `log`
  crate's `kv_unstable` feature should update to `log v0.4.18` or later.
- [Add a `sysroot` crate to represent the standard library crates.](https://github.com/rust-lang/rust/pull/108865/)
  This does not affect stable users, but may require adjustment in tools that build their own standard library.
- [Cargo optimizes its usage under `rustup`.](https://github.com/rust-lang/cargo/pull/11917/) When
  Cargo detects it will run `rustc` pointing to a rustup proxy, it'll try bypassing the proxy and
  use the underlying binary directly. There are assumptions around the interaction with rustup and
  `RUSTUP_TOOLCHAIN`. However, it's not expected to affect normal users.
- [When querying a package, Cargo tries only the original name, all hyphens, and all underscores to
  handle misspellings.](https://github.com/rust-lang/cargo/pull/12083/) Previously, Cargo tried each
  combination of hyphens and underscores, causing excessive requests to crates.io.
- Cargo now [disallows `RUSTUP_HOME`](https://github.com/rust-lang/cargo/pull/12101/) and
  [`RUSTUP_TOOLCHAIN`](https://github.com/rust-lang/cargo/pull/12107/) in the `[env]` configuration
  table. This is considered to be not a use case Cargo would like to support, since it will likely
  cause problems or lead to confusion.
