- [`core::ffi::FromBytesUntilNulError`](https://doc.rust-lang.org/stable/core/ffi/struct.FromBytesUntilNulError.html)
These APIs are now stable in const contexts:

## Rustdoc
- [Vertically compact trait bound formatting.](https://togithub.com/rust-lang/rust/pull/102842/)
- [Only include stable lints in `rustdoc::all` group.](https://togithub.com/rust-lang/rust/pull/106316/)

- [Remove inconsistently-present sidebar tooltips.](https://togithub.com/rust-lang/rust/pull/107490/)
- [Search by macro when query ends with `!`.](https://togithub.com/rust-lang/rust/pull/108143/)
## Compatibility Notes
- [The `rust-analysis` component from `rustup` now only contains a warning placeholder.](https://togithub.com/rust-lang/rust/pull/101841/) This was primarily intended for RLS, and the corresponding `-Zsave-analysis` flag has been removed from the compiler as well.
- [Unaligned references to packed fields are now a hard error.](https://togithub.com/rust-lang/rust/pull/102513/) This has been a warning since 1.53, and denied by default with a future-compatibility warning since 1.62.
- [Update the minimum external LLVM to 14.](https://togithub.com/rust-lang/rust/pull/107573/)
- [Cargo now emits errors on invalid characters in a registry token.](https://togithub.com/rust-lang/cargo/pull/11600/)
- [When `default-features` is set to false of a workspace dependency, and an inherited dependency of a member has `default-features = true`, Cargo will enable default features of that dependency.](https://togithub.com/rust-lang/cargo/pull/11409/)
- [Cargo denies `CARGO_HOME` in the `[env]` configuration table. Cargo itself doesn't pick up this value, but recursive calls to cargo would, which was not intended.](https://togithub.com/rust-lang/cargo/pull/11644/)
- [Debuginfo for build dependencies is now off if not explicitly set. This is expected to improve the overall build time.](https://togithub.com/rust-lang/cargo/pull/11252/)
- [The Rust distribution no longer always includes rustdoc](https://togithub.com/rust-lang/rust/pull/106886)
If `tools = [...]` is set in config.toml, we will respect a missing rustdoc in that list. By
default rustdoc remains included. To retain the prior behavior explicitly add `"rustdoc"` to the
list.
## 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.
- [Move `format_args!()` into AST (and expand it during AST lowering)](https://togithub.com/rust-lang/rust/pull/106745/)
### [`v1.68.2`](https://togithub.com/rust-lang/rust/blob/HEAD/RELEASES.md#Version-1682-2023-03-28)
[Compare Source](https://togithub.com/rust-lang/rust/compare/1.68.1...1.68.2)
\===========================
- [Update the GitHub RSA host key bundled within Cargo](https://togithub.com/rust-lang/cargo/pull/11883).
The key was [rotated by GitHub](https://github.blog/2023-03-23-we-updated-our-rsa-ssh-host-key/)
on 2023-03-24 after the old one leaked.
- [Mark the old GitHub RSA host key as revoked](https://togithub.com/rust-lang/cargo/pull/11889).
This will prevent Cargo from accepting the leaked key even when trusted by
the system.
- [Add support for `@revoked` and a better error message for `@cert-authority` in Cargo's SSH host key verification](https://togithub.com/rust-lang/cargo/pull/11635)
### [`v1.68.1`](https://togithub.com/rust-lang/rust/blob/HEAD/RELEASES.md#Version-1681-2023-03-23)
[Compare Source](https://togithub.com/rust-lang/rust/compare/1.68.0...1.68.1)
\===========================
- [Fix miscompilation in produced Windows MSVC artifacts](https://togithub.com/rust-lang/rust/pull/109094)
This was introduced by enabling ThinLTO for the distributed rustc which led
to miscompilations in the resulting binary. Currently this is believed to be
limited to the -Zdylib-lto flag used for rustc compilation, rather than a
general bug in ThinLTO, so only rustc artifacts should be affected.
- [Fix --enable-local-rust builds](https://togithub.com/rust-lang/rust/pull/109111/)
- [Treat `$prefix-clang` as `clang` in linker detection code](https://togithub.com/rust-lang/rust/pull/109156)

## Compatibility Notes
- [The layout of `repr(Rust)` types now groups m\*2^n-sized fields with
equivalently aligned ones.](https://togithub.com/rust-lang/rust/pull/102750/)
This is intended to be an optimization, but it is also known to increase type
sizes in a few cases for the placement of enum tags. As a reminder, the layout
of `repr(Rust)` types is an implementation detail, subject to change.
- [0.5 now rounds to 0 when formatted to 0 decimal places.](https://togithub.com/rust-lang/rust/pull/102935/)
This makes it consistent with the rest of floating point formatting that
rounds ties toward even digits.
- [Chains of `&&` and `||` will now drop temporaries from their sub-expressions in
evaluation order, left-to-right.](https://togithub.com/rust-lang/rust/pull/103293/)
Previously, it was "twisted" such that the *first* expression dropped its
temporaries *last*, after all of the other expressions dropped in order.
- [Underscore suffixes on string literals are now a hard error.](https://togithub.com/rust-lang/rust/pull/103914/)
This has been a future-compatibility warning since 1.20.0.
- [Stop passing `-export-dynamic` to `wasm-ld`.](https://togithub.com/rust-lang/rust/pull/105405/)
- [`main` is now mangled as `__main_void` on `wasm32-wasi`.](https://togithub.com/rust-lang/rust/pull/105468/)
- [Cargo now emits an error if there are multiple registries in the configuration
with the same index URL.](https://togithub.com/rust-lang/cargo/pull/10592)

[Unaligned references to packed fields are now a hard error.](https://togithub.com/rust-lang/rust/pull/102513/) This has been a warning since 1.53, and denied by default with a future-compatibility warning since 1.62. -

By default rustdoc remains included. To retain the prior behavior explicitly add `"rustdoc"` to the list. ## 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. - [Move `format_args!()` into AST (and expand it during AST lowering)](https://togithub.com/rust-lang/rust/pull/106745/) ### [`v1.68.2`](https://togithub.com/rust-lang/rust/blob/HEAD/RELEASES.md#Version-1682-2023-03-28) [Compare Source](https://togithub.com/rust-lang/rust/compare/1.68.1...1.68.2) \=========================== - [Update the GitHub RSA host key bundled within Cargo](https://togithub.com/rust-lang/cargo/pull/11883). The key was [rotated by GitHub](https://github.blog/2023-03-23-we-updated-our-rsa-ssh-host-key/) on 2023-03-24 after the old one leaked. - [Mark the old GitHub RSA host key as revoked](https://togithub.com/rust-lang/cargo/pull/11889). This will prevent Cargo from accepting the leaked key even when trusted by the system. - [Add support for `@revoked` and a better error message for `@cert-authority` in Cargo's SSH host key verification](https://togithub.com/rust-lang/cargo/pull/11635) ### [`v1.68.1`](https://togithub.com/rust-lang/rust/blob/HEAD/RELEASES.md#Version-1681-2023-03-23) [Compare Source](https://togithub.com/rust-lang/rust/compare/1.68.0...1.68.1) \=========================== - [Fix miscompilation in produced Windows MSVC artifacts](https://togithub.com/rust-lang/rust/pull/109094) This was introduced by enabling ThinLTO for the distributed rustc which led to miscompilations in the resulting binary. Currently this is believed to be limited to the -Zdylib-lto flag used for rustc compilation, rather than a general bug in ThinLTO, so only rustc artifacts should be affected. - [Fix --enable-local-rust builds](https://togithub.com/rust-lang/rust/pull/109111/) - [Treat `$prefix-clang` as `clang` in linker detection code](https://togithub.com/rust-lang/rust/pull/109156) - [Fix panic in compiler code](https://togithub.com/rust-lang/rust/pull/108162) ### [`v1.68.0`](https://togithub.com/rust-lang/rust/blob/HEAD/RELEASES.md#Version-1680-2023-03-09) [Compare Source](https://togithub.com/rust-lang/rust/compare/1.67.1...1.68.0) \========================== ## Language - [Stabilize default_alloc_error_handler](https://togithub.com/rust-lang/rust/pull/102318/) This allows usage of `alloc` on stable without requiring the definition of a handler for allocation failure. Defining custom handlers is still unstable. - [Stabilize `efiapi` calling convention.](https://togithub.com/rust-lang/rust/pull/105795/) - [Remove implicit promotion for types with drop glue](https://togithub.com/rust-lang/rust/pull/105085/) ## Compiler - [Change `bindings_with_variant_name` to deny-by-default](https://togithub.com/rust-lang/rust/pull/104154/) - [Allow .. to be parsed as let initializer](https://togithub.com/rust-lang/rust/pull/105701/) - [Add `armv7-sony-vita-newlibeabihf` as a tier 3 target](https://togithub.com/rust-lang/rust/pull/105712/) - [Always check alignment during compile-time const evaluation](https://togithub.com/rust-lang/rust/pull/104616/) - [Disable "split dwarf inlining" by default.](https://togithub.com/rust-lang/rust/pull/106709/) - [Add vendor to Fuchsia's target triple](https://togithub.com/rust-lang/rust/pull/106429/) - [Enable sanitizers for s390x-linux](https://togithub.com/rust-lang/rust/pull/107127/) ## Libraries - [Loosen the bound on the Debug implementation of Weak.](https://togithub.com/rust-lang/rust/pull/90291/) - [Make `std::task::Context` !Send and !Sync](https://togithub.com/rust-lang/rust/pull/95985/) - [PhantomData layout guarantees](https://togithub.com/rust-lang/rust/pull/104081/) - [Don't derive Debug for `OnceWith` & `RepeatWith`](https://togithub.com/rust-lang/rust/pull/104163/) - [Implement DerefMut for PathBuf](https://togithub.com/rust-lang/rust/pull/105018/) - [Add O(1) `Vec -> VecDeque` conversion guarantee](https://togithub.com/rust-lang/rust/pull/105128/) - [Leak amplification for peek_mut() to ensure BinaryHeap's invariant is always met](https://togithub.com/rust-lang/rust/pull/105851/) ## Stabilized APIs - [`{core,std}::pin::pin!`](https://doc.rust-lang.org/stable/std/pin/macro.pin.html) - [`impl FromConfiguration
