Libraries---------- [Bump Unicode to version 15.1.0, regenerate tables](https://github.com/rust-lang/rust/pull/120777/)- [Make align_offset, align_to well-behaved in all cases](https://github.com/rust-lang/rust/pull/121201/)- [PartialEq, PartialOrd: document expectations for transitive chains](https://github.com/rust-lang/rust/pull/115386/)- [Optimize away poison guards when std is built with panic=abort](https://github.com/rust-lang/rust/pull/100603/)- [Replace pthread `RwLock` with custom implementation](https://github.com/rust-lang/rust/pull/110211/)- [Implement unwind safety for Condvar on all platforms](https://github.com/rust-lang/rust/pull/121768/)- [Add ASCII fast-path for `char::is_grapheme_extended`](https://github.com/rust-lang/rust/pull/121138/) Stabilized APIs- [`impl Read for &Stdin`](https://doc.rust-lang.org/stable/std/io/struct.Stdin.html#impl-Read-for-%26Stdin)- [Accept non `\'static` lifetimes for several `std::error::Error` related implementations](https://github.com/rust-lang/rust/pull/113833/)- [Make `impl` impl take `?Sized`](https://github.com/rust-lang/rust/pull/114655/)- [`impl From for io::Error`](https://doc.rust-lang.org/stable/std/io/struct.Error.html#impl-From%3CTryReserveError%3E-for-Error) These APIs are now stable in const contexts:- [`Barrier::new()`](https://doc.rust-lang.org/stable/std/sync/struct.Barrier.html#method.new) Cargo------ [Stabilize lockfile v4](https://github.com/rust-lang/cargo/pull/12852/)- [Respect `rust-version` when generating lockfile](https://github.com/rust-lang/cargo/pull/12861/)- [Control `--charset` via auto-detecting config value](https://github.com/rust-lang/cargo/pull/13337/)- [Support `target..rustdocflags` officially](https://github.com/rust-lang/cargo/pull/13197/)- [Stabilize global cache data tracking](https://github.com/rust-lang/cargo/pull/13492/) Misc----- [rustdoc: add `--test-builder-wrapper` arg to support wrappers such as RUSTC_WRAPPER when building doctests](https://github.com/rust-lang/rust/pull/114651/) Compatibility Notes- [Many unsafe precondition checks now run for user code with debug assertions enabled](https://github.com/rust-lang/rust/pull/120594/) This change helps users catch undefined behavior in their code, though the details of how much is checked are generally not stable.- [riscv only supports split_debuginfo=off for now](https://github.com/rust-lang/rust/pull/120518/)- [Consistently check bounds on hidden types of `impl Trait`](https://github.com/rust-lang/rust/pull/121679)- [Change equality of higher ranked types to not rely on subtyping](https://github.com/rust-lang/rust/pull/118247)- [When called, additionally check bounds on normalized function return type](https://github.com/rust-lang/rust/pull/118882)- [Expand coverage for `arithmetic_overflow` lint](https://github.com/rust-lang/rust/pull/119432/)- [Fix detection of potential interior mutability in `const` initializers](https://github.com/rust-lang/rust/issues/121250) This code was accidentally accepted. The fix can break generic code that borrows a value of unknown type, as there is currently no way to declare \"this type has no interior mutability\". In the future, stabilizing the [`Freeze` trait](https://github.com/rust-lang/rust/issues/121675) will allow proper support for such code.
