Version 1.62.0 (2022-06-30)
==========================

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 ones.][95035]
- [Replace RwLock by a futex based one on Linux][95801]
- [std: directly use pthread in UNIX parker implementation][96393]

Stabilized APIs
---------------

- [`bool::then_some`]
- [`f32::total_cmp`]
- [`f64::total_cmp`]
- [`Stdin::lines`]
- [`windows::CommandExt::raw_arg`]
- [`impl<T: Default> Default for AssertUnwindSafe<T>`]
- [`From<Rc<str>> for Rc<[u8]>`][rc-u8-from-str]
- [`From<Arc<str>> for Arc<[u8]>`][arc-u8-from-str]
- [`FusedIterator for EncodeWide`]
- [RDM intrinsics on aarch64][stdarch/1285]

Clippy
------

- [Create clippy lint against unexpectedly late drop for temporaries
  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](rust-lang/cargo#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.

  Trait` return types.][98608]
* [The compiler fixed an incremental compilation bug with `async
  fn` lifetimes.][98890]
* [Windows added a fallback for overlapped I/O in synchronous reads
  and writes.][98950]
* [The `x86_64-fortanix-unknown-sgx` target added a mitigation for the

Version 1.61.0 (2022-05-19)
==========================

Language
--------

- [`const fn` signatures can now include generic trait bounds][93827]
- [`const fn` signatures can now use `impl Trait` in argument and return
  position][93827]
- [Function pointers can now be created, cast, and passed around in a
  `const fn`][93827]
- [Recursive calls can now set the value of a function's opaque
  `impl Trait` return type][94081]

Compiler
--------

- [Linking modifier syntax in `#[link]` attributes and on the command
  line, as well as the `whole-archive` modifier specifically, are now
  supported][93901]
- [The `char` type is now described as UTF-32 in debuginfo][89887]
- The [`#[target_feature]`][target_feature] attribute
  [can now be used with aarch64 features][90621]
- X86 [`#[target_feature = "adx"]` is now stable][93745]

Libraries
---------

- [`ManuallyDrop<T>` is now documented to have the same layout as `T`][88375]
- [`#[ignore = "#"]` messages are printed when running tests][92714]
- [Consistently show absent stdio handles on Windows as NULL handles][93263]
- [Make `std::io::stdio::lock()` return `'static` handles.][93965]
  Previously, the creation of locked handles to stdin/stdout/stderr would
  borrow the handles being locked, which prevented writing
  `let out = std::io::stdout().lock();` because `out` would outlive
  the return value of `stdout()`.
  Such code now works, eliminating a common pitfall that affected many
  Rust users.
- [`Vec::from_raw_parts` is now less restrictive about its inputs][95016]
- [`std::thread::available_parallelism` now takes cgroup quotas into
  account.][92697] Since `available_parallelism` is often used to create a
  thread pool for parallel computation, which may be CPU-bound for
  performance, `available_parallelism` will return a value consistent with
  the ability to use that many threads continuously, if possible.
  For instance, in a container with 8 virtual CPUs but quotas only allowing
  for 50% usage, `available_parallelism` will return 4.

Stabilized APIs
---------------

- [`Pin::static_mut`]
- [`Pin::static_ref`]
- [`Vec::retain_mut`]
- [`VecDeque::retain_mut`]
- [`Write` for `Cursor<[u8; N]>`][cursor-write-array]
- [`std::os::unix::net::SocketAddr::from_pathname`]
- [`std::process::ExitCode`] and [`std::process::Termination`].
  The stabilization of these two API s now makes it possible for
  programs to return errors from `main` with custom exit codes.
- [`std::thread::JoinHandle::is_finished`]

These APIs are now usable in const contexts:

- [`<*const T>::offset` and `<*mut T>::offset`][ptr-offset]
- [`<*const T>::wrapping_offset` and `<*mut T>::wrapping_offset`]
  [ptr-wrapping_offset]
- [`<*const T>::add` and `<*mut T>::add`][ptr-add]
- [`<*const T>::sub` and `<*mut T>::sub`][ptr-sub]
- [`<*const T>::wrapping_add` and `<*mut T>::wrapping_add`][ptr-wrapping_add]
- [`<*const T>::wrapping_sub` and `<*mut T>::wrapping_sub`][ptr-wrapping_sub]
- [`<[T]>::as_mut_ptr`][slice-as_mut_ptr]
- [`<[T]>::as_ptr_range`][slice-as_ptr_range]
- [`<[T]>::as_mut_ptr_range`][slice-as_mut_ptr_range]

Cargo
-----

No feature changes, but see compatibility notes.

Compatibility Notes
-------------------

- Previously native static libraries were linked as `whole-archive` in
  some cases, but now rustc tries not to use `whole-archive` unless
  explicitly requested. This [change][93901] may result in linking errors
  in some cases. To fix such errors, native libraries linked from the
  command line, build scripts, or [`#[link]` attributes][link-attr] need to
  - (more common) either be reordered to respect dependencies between them
    (if `a` depends on `b` then `a` should go first and `b` second)
  - (less common) or be updated to use the [`+whole-archive`] modifier.
- [Catching a second unwind from FFI code while cleaning up from a Rust
  panic now causes the process to abort][92911]
- [Proc macros no longer see `ident` matchers wrapped in groups][92472]
- [The number of `#` in `r#` raw string literals is now required to be
  less than 256][95251]
- [When checking that a dyn type satisfies a trait bound, supertrait
  bounds are now enforced][92285]
- [`cargo vendor` now only accepts one value for each `--sync` flag]
  [cargo/10448]
- [`cfg` predicates in `all()` and `any()` are always evaluated to detect
  errors, instead of short-circuiting.][94295] The compatibility
  considerations here arise in nightly-only code that used the
  short-circuiting behavior of `all` to write something like
  `cfg(all(feature = "nightly", syntax-requiring-nightly))`, which
  will now fail to compile. Instead, use either `cfg_attr(feature
  = "nightly", ...)` or nested uses of `cfg`.
- [bootstrap: static-libstdcpp is now enabled by default, and can
  now be disabled when llvm-tools is enabled][94832]

Internal Changes
----------------

These changes provide no direct user facing benefits, but represent
significant improvements to the internals and overall performance
of rustc and related tools.

- [debuginfo: Refactor debuginfo generation for types][94261]
- [Remove the everybody loops pass][93913]
