madsmtm · 2026-02-02T23:04:34Z

Promote the following targets to Tier 2 without host tools:

aarch64-apple-tvos.
aarch64-apple-tvos-sim.
aarch64-apple-watchos.
aarch64-apple-watchos-sim.
aarch64-apple-visionos.
aarch64-apple-visionos-sim.

This implements MCP rust-lang/compiler-team#918. Fixes #151705.

Unsure how exactly I'd verify that this doesn't take too long? Do I need to run bors twice, once to populate the cache, and the second time to actually time it?

Previously, they could not be used without the standard library, which has no stable build mechanism. In preparation for the `build-std` project adding that support, JSON target specs are being proactively gated to ensure they remain unstable even if `build-std` is stabilized. Cargo now includes the `-Z json-target-spec` CLI flag to automatically pass `-Z unstable-options` to the compiler when needed.

[In search results, rank unstable items lower](rust-lang/rust#149460) - [Add new "hide deprecated items" setting in rustdoc](rust-lang/rust#151091) <a id="1.95-Compatibility-Notes"></a> ## Compatibility Notes - [Array coercions may now result in less inference constraints than before](rust-lang/rust#140283) - Importing `$crate` without renaming, i.e. `use $crate::{self};`, is now no longer permitted due to stricter error checking for `self` imports. - [const-eval: be more consistent in the behavior of padding during typed copies.](rust-lang/rust#148967) In very rare cases, this may cause compilation errors due to bytes from parts of a pointer ending up in the padding bytes of a `const` or `static`. - [A future-incompatibility warning lint `ambiguous_glob_imported_traits` is now reported when using an ambiguously glob imported trait](rust-lang/rust#149058) - [Check lifetime bounds of types mentioning only type parameters](rust-lang/rust#149389) - [Report more visibility-related ambiguous import errors](rust-lang/rust#149596) - [Deprecate `Eq::assert_receiver_is_total_eq` and emit future compatibility warnings on manual impls](rust-lang/rust#149978) - [powerpc64: Use the ELF ABI version set in target spec instead of guessing](rust-lang/rust#150468) (fixes the ELF ABI used by the OpenBSD target) - Matching on a `#[non_exhaustive]` enum [now reads the discriminant, even if the enum has only one variant](rust-lang/rust#150681). This can cause closures to capture values that they previously wouldn't. - `mut ref` and `mut ref mut` patterns, part of the unstable [Match Ergonomics 2024 RFC](rust-lang/rust#123076), were accidentally allowed on stable within struct pattern field shorthand. These patterns are now correctly feature-gated as unstable in this position. - [Add future-compatibility warning for derive helper attributes which conflict with built-in attributes](rust-lang/rust#151152) - [JSON target specs](https://doc.rust-lang.org/rustc/targets/custom.html) have been destabilized and now require `-Z unstable-options` to use. Previously, they could not be used without the standard library, which has no stable build mechanism. In preparation for the `build-std` project adding that support, JSON target specs are being proactively gated to ensure they remain unstable even if `build-std` is stabilized. Cargo now includes the `-Z json-target-spec` CLI flag to automatically pass `-Z unstable-options` to the compiler when needed. See [#150151](rust-lang/rust#150151), [#151534](rust-lang/rust#150151), and [rust-lang/cargo#16557](rust-lang/cargo#16557). - [The arguments of `#[feature]` attributes on invalid targets are now checked](rust-lang/rust#153764) <a id="1.95-Internal-Changes"></a> ## 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 tools. - [Update to LLVM 22](rust-lang/rust#150722) ### [`v1.94.1`](https://github.com/rust-lang/rust/blob/HEAD/RELEASES.md#Version-1941-2026-03-26) [Compare Source](rust-lang/rust@1.94.0...1.94.1) \=========================== <a id="1.94.1"></a> - [Fix `std::thread::spawn` on wasm32-wasip1-threads](rust-lang/rust#153634) - [Remove new methods added to `std::os::windows::fs::OpenOptionsExt`](rust-lang/rust#153491) The new methods were unstable, but the trait itself is not sealed and so cannot be extended with non-default methods. - [Clippy: fix ICE in `match_same_arms`](rust-lang/rust-clippy#16685) - [Cargo: update tar to 0.4.45](rust-lang/cargo#16769) This resolves CVE-2026-33055 and CVE-2026-33056. Users of crates.io are not affected.
