`./configure` is the recommended way to programatically generate a `config.toml`. `make` is not
recommended (we suggest using `x.py` directly), but it is supported and we try not to break it
unnecessarily.

Version 1.71.0 (2023-07-13)
==========================
<a id="1.71.0-Language"></a>
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/)
<a id="1.71.0-Compiler"></a>
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.
<a id="1.71.0-Libraries"></a>
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.

<a id="1.71.0-Compatibility-Notes"></a>
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.

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
