+Language +-------- + +- [Stabilize `#[derive(Default)]` on enums with a `#[default]` variant][94457] +- [Stop validating some checks in dead code after functions with uninhabited return types][93313] +- [Fix constants not getting dropped if part of a diverging expression][94775] +- [Support unit struct/enum variant in destructuring assignment][95380] +- [Remove mutable_borrow_reservation_conflict lint and allow the code pattern][96268] + +Compiler +-------- + +- [linker: Stop using whole-archive on dependencies of dylibs][96436] +- [Make `unaligned_references` lint deny-by-default][95372] + This lint is also a future compatibility lint, and is expected to eventually + become a hard error. +- [Only add codegen backend to dep info if -Zbinary-dep-depinfo is used][93969] +- [Reject `#[thread_local]` attribute on non-static items][95006] +- [Add tier 3 `aarch64-pc-windows-gnullvm` and `x86_64-pc-windows-gnullvm` targets\*][94872] +- [Implement a lint to warn about unused macro rules][96150] +- [Promote `x86_64-unknown-none` target to Tier 2\*][95705] + +\* Refer to Rust's [platform support page][platform-support-doc] for more + information on Rust's tiered platform support. + +Libraries +--------- + +- [Move `CStr` to libcore, and `CString` to liballoc][94079] +- [Windows: Use a pipe relay for chaining pipes][95841] +- [Replace Linux Mutex and Condvar with futex based

in match scrutinee expressions][94206] + +Cargo +----- + +- Added the `cargo add` command for adding dependencies to `Cargo.toml` from + the command-line. + [docs](https://doc.rust-lang.org/nightly/cargo/commands/cargo-add.html) +- Package ID specs now support `name@version` syntax in addition to the + previous `name:version` to align with the behavior in `cargo add` and other + tools. `cargo install` and `cargo yank` also now support this syntax so the + version does not need to passed as a separate flag. +- The `git` and `registry` directories in Cargo's home directory (usually + `~/.cargo`) are now marked as cache directories so that they are not + included in backups or content indexing (on Windows). +- Added automatic `@` argfile support, which will use "response files" if the + command-line to `rustc` exceeds the operating system's limit. + +Compatibility Notes +------------------- + +- `cargo test` now passes `--target` to `rustdoc` if the specified target is + the same as the host target. + [#10594](https://github.com/rust-lang/cargo/pull/10594) +- [rustdoc: Remove .woff font files][96279] +- [Enforce Copy bounds for repeat elements while considering lifetimes][95819] + +Internal Changes +---------------- + +- [Unify ReentrantMutex implementations across all platforms][96042] + +These changes provide no direct user facing benefits, but represent significant +improvements to the internals and overall performance of rustc +and related tools. + +[93313]: https://github.com/rust-lang/rust/pull/93313/ +[93969]:
