[`str::from_utf8_unchecked_mut`] (https://doc.rust-lang.org/stable/core/str/fn.from_utf8_unchecked_mut.html) Cargo ----- - [Introduced a new `CARGO_MANIFEST_PATH` environment variable, similar to `CARGO_MANIFEST_DIR` but pointing directly to the manifest file.] (rust-lang/cargo#14404) - [Added `package.autolib` to the manifest, allowing `[lib]` auto-discovery to be disabled.] (rust-lang/cargo#14591) - [Declare support level for each crate in Cargo's Charter / crate docs.] (rust-lang/cargo#14600) - [Declare new Intentional Artifacts as 'small' changes.] (rust-lang/cargo#14599) Rustdoc ------- - [The sidebar / hamburger menu table of contents now includes the `# headers` from the main item's doc comment] (rust-lang/rust#120736). This is similar to a third-party feature provided by the rustdoc-search-enhancements browser extension. Compatibility Notes ------------------- - [Warn against function pointers using unsupported ABI strings.] (rust-lang/rust#128784) - [Check well-formedness of the source type's signature in fn pointer casts.] (rust-lang/rust#129021) This partly closes a soundness hole that comes when casting a function item to function pointer - [Use equality instead of subtyping when resolving type dependent paths.] (rust-lang/rust#129073) - Linking on macOS now correctly includes Rust's default deployment target. Due to a linker bug, you might have to pass `MACOSX_DEPLOYMENT_TARGET` or fix your `#[link]` attributes to point to the correct frameworks. See <rust-lang/rust#129369>. - [Rust will now correctly raise an error for `repr(Rust)` written on non-`struct`/`enum`/`union` items, since it previous did not have any effect.] (rust-lang/rust#129422) - The future incompatibility lint `deprecated_cfg_attr_crate_type_name` [has been made into a hard error] (rust-lang/rust#129670). It was used to deny usage of `#![crate_type]` and `#![crate_name]` attributes in `#![cfg_attr]`, which required a hack in the compiler to be able to change the used crate type and crate name after cfg expansion. Users can use `--crate-type` instead of `#![cfg_attr(..., crate_type = "...")]` and `--crate-name` instead of `#![cfg_attr(..., crate_name = "...")]` when running `rustc`/`cargo rustc` on the command line. Use of those two attributes outside of `#![cfg_attr]` continue to be fully supported. - Until now, paths into the sysroot were always prefixed with `/rustc/$hash` in diagnostics, codegen, backtrace, e.g. ``` thread 'main' panicked at 'hello world', map-panic.rs:2:50 stack backtrace: 0: std::panicking::begin_panic at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/std/src/panicking.rs:616:12 1: map_panic::main::{{closure}} at ./map-panic.rs:2:50 2: core::option::Option<T>::map at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/option.rs:929:29 3: map_panic::main at ./map-panic.rs:2:30 4: core::ops::function::FnOnce::call_once at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/ops/function.rs:248:5 note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace. ``` [RFC 3127 said] (https://rust-lang.github.io/rfcs/3127-trim-paths.html#changing-handling-of-sysroot-path-in-rustc) > We want to change this behaviour such that, when `rust-src` source files can be discovered, the virtual path is discarded and therefore the local path will be embedded, unless there is a `--remap-path-prefix` that causes this local path to be remapped in the usual way. [#129687](rust-lang/rust#129687) implements this behaviour, when `rust-src` is present at compile time, `rustc` replaces `/rustc/$hash` with a real path into the local `rust-src` component with best effort. To sanitize this, users must explicitly supply `--remap-path-prefix=<path to rust-src>=foo` or not have the `rust-src` component installed. - The allow-by-default `missing_docs` lint used to disable itself when invoked through `rustc --test`/`cargo test`, resulting in `#[expect(missing_docs)]` emitting false positives due to the expectation being wrongly unfulfilled. This behavior [has now been removed] (rust-lang/rust#130025), which allows `#[expect(missing_docs)]` to be fulfilled in all scenarios, but will also report new `missing_docs` diagnostics for publicly reachable `#[cfg(test)]` items, [integration test] (https://doc.rust-lang.org/cargo/reference/cargo-targets.html#integration-tests) crate-level documentation, and publicly reachable items in integration tests. - [The `armv8r-none-eabihf` target now uses the Armv8-R required set of floating-point features.] (rust-lang/rust#130295) - [Fix a soundness bug where rustc wouldn't detect unconstrained higher-ranked lifetimes in a `dyn Trait`'s associated types that occur due to supertraits.] (rust-lang/rust#130367) - [Update the minimum external LLVM version to 18.] (rust-lang/rust#130487) - [Remove `aarch64-fuchsia` and `x86_64-fuchsia` target aliases in favor of `aarch64-unknown-fuchsia` and `x86_64-unknown-fuchsia` respectively.] (rust-lang/rust#130657) - [The ABI-level exception class of a Rust panic is now encoded with native-endian bytes, so it is legible in hex dumps.] (rust-lang/rust#130897) - [Visual Studio 2013 is no longer supported for MSVC targets.] (rust-lang/rust#131070) - [The sysroot no longer contains the `std` dynamic library in its top-level `lib/` dir.] (rust-lang/rust#131188)

This is similar to a third-party feature provided by the rustdoc-search-enhancements browser extension. <a id="1.83.0-Compatibility-Notes"></a> ## Compatibility Notes - [Warn against function pointers using unsupported ABI strings.](rust-lang/rust#128784) - [Check well-formedness of the source type's signature in fn pointer casts.](rust-lang/rust#129021) This partly closes a soundness hole that comes when casting a function item to function pointer - [Use equality instead of subtyping when resolving type dependent paths.](rust-lang/rust#129073) - Linking on macOS now correctly includes Rust's default deployment target. Due to a linker bug, you might have to pass `MACOSX_DEPLOYMENT_TARGET` or fix your `#[link]` attributes to point to the correct frameworks. See [#​129369](rust-lang/rust#129369). - [Rust will now correctly raise an error for `repr(Rust)` written on non-`struct`/`enum`/`union` items, since it previous did not have any effect.](rust-lang/rust#129422) - The future incompatibility lint `deprecated_cfg_attr_crate_type_name` [has been made into a hard error](rust-lang/rust#129670). It was used to deny usage of `#![crate_type]` and `#![crate_name]` attributes in `#![cfg_attr]`, which required a hack in the compiler to be able to change the used crate type and crate name after cfg expansion. Users can use `--crate-type` instead of `#![cfg_attr(..., crate_type = "...")]` and `--crate-name` instead of `#![cfg_attr(..., crate_name = "...")]` when running `rustc`/`cargo rustc` on the command line. Use of those two attributes outside of `#![cfg_attr]` continue to be fully supported. - Until now, paths into the sysroot were always prefixed with `/rustc/$hash` in diagnostics, codegen, backtrace, e.g. thread 'main' panicked at 'hello world', map-panic.rs:2:50 stack backtrace: 0: std::panicking::begin_panic at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/std/src/panicking.rs:616:12 1: map_panic::main::{{closure}} at ./map-panic.rs:2:50 2: core::option::Option<T>::map at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/option.rs:929:29 3: map_panic::main at ./map-panic.rs:2:30 4: core::ops::function::FnOnce::call_once at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/ops/function.rs:248:5 note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace. [RFC 3127 said](https://rust-lang.github.io/rfcs/3127-trim-paths.html#changing-handling-of-sysroot-path-in-rustc) > We want to change this behaviour such that, when `rust-src` source files can be discovered, the virtual path is discarded and therefore the local path will be embedded, unless there is a `--remap-path-prefix` that causes this local path to be remapped in the usual way. [#​129687](rust-lang/rust#129687) implements this behaviour, when `rust-src` is present at compile time, `rustc` replaces `/rustc/$hash` with a real path into the local `rust-src` component with best effort. To sanitize this, users must explicitly supply `--remap-path-prefix=<path to rust-src>=foo` or not have the `rust-src` component installed. - The allow-by-default `missing_docs` lint used to disable itself when invoked through `rustc --test`/`cargo test`, resulting in `#[expect(missing_docs)]` emitting false positives due to the expectation being wrongly unfulfilled. This behavior [has now been removed](rust-lang/rust#130025), which allows `#[expect(missing_docs)]` to be fulfilled in all scenarios, but will also report new `missing_docs` diagnostics for publicly reachable `#[cfg(test)]` items, [integration test](https://doc.rust-lang.org/cargo/reference/cargo-targets.html#integration-tests) crate-level documentation, and publicly reachable items in integration tests. - [The `armv8r-none-eabihf` target now uses the Armv8-R required set of floating-point features.](rust-lang/rust#130295) - [Fix a soundness bug where rustc wouldn't detect unconstrained higher-ranked lifetimes in a `dyn Trait`'s associated types that occur due to supertraits.](rust-lang/rust#130367) - [Update the minimum external LLVM version to 18.](rust-lang/rust#130487) - [Remove `aarch64-fuchsia` and `x86_64-fuchsia` target aliases in favor of `aarch64-unknown-fuchsia` and `x86_64-unknown-fuchsia` respectively.](rust-lang/rust#130657) - [The ABI-level exception class of a Rust panic is now encoded with native-endian bytes, so it is legible in hex dumps.](rust-lang/rust#130897) - [Visual Studio 2013 is no longer supported for MSVC targets.](rust-lang/rust#131070) - [The sysroot no longer contains the `std` dynamic library in its top-level `lib/` dir.](rust-lang/rust#131188) </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.
