## Language

- [Stabilize `#![feature(let_chains)]` in the 2024
edition.](https://redirect.github.com/rust-lang/rust/pull/132833)
This feature allows `&&`-chaining `let` statements inside `if` and
`while`, allowing intermixture with boolean expressions. The patterns
inside the `let` sub-expressions can be irrefutable or refutable.
- [Stabilize
`#![feature(naked_functions)]`.](https://redirect.github.com/rust-lang/rust/pull/134213)
Naked functions allow writing functions with no compiler-generated
epilogue and prologue, allowing full control over the generated assembly
for a particular function.
- [Stabilize
`#![feature(cfg_boolean_literals)]`.](https://redirect.github.com/rust-lang/rust/pull/138632)
This allows using boolean literals as `cfg` predicates, e.g.
`#[cfg(true)]` and `#[cfg(false)]`.
- [Fully de-stabilize the `#[bench]`
attribute](https://redirect.github.com/rust-lang/rust/pull/134273).
Usage of `#[bench]` without `#![feature(custom_test_frameworks)]`
already triggered a deny-by-default future-incompatibility lint since
Rust 1.77, but will now become a hard error.
- [Add warn-by-default `dangerous_implicit_autorefs` lint against
implicit autoref of raw pointer
dereference.](https://redirect.github.com/rust-lang/rust/pull/123239)
The lint [will be bumped to
deny-by-default](https://redirect.github.com/rust-lang/rust/pull/141661)
in the next version of Rust.
- [Add `invalid_null_arguments` lint to prevent invalid usage of null
pointers.](https://redirect.github.com/rust-lang/rust/pull/119220)
  This lint is uplifted from `clippy::invalid_null_ptr_usage`.
- [Change trait impl candidate preference for builtin impls and trivial
where-clauses.](https://redirect.github.com/rust-lang/rust/pull/138176)
- [Check types of generic const parameter
defaults](https://redirect.github.com/rust-lang/rust/pull/139646)

information to
generate.](https://redirect.github.com/rust-lang/rust/pull/136926)

## Platform Support

- [Demote `i686-pc-windows-gnu` to Tier
2.](https://blog.rust-lang.org/2025/05/26/demoting-i686-pc-windows-gnu/)

indices.](https://redirect.github.com/rust-lang/rust/pull/139099), for
those passing it a stateful closure.
- [The libtest flag `--nocapture` is deprecated in favor of the more
consistent `--no-capture`
flag.](https://redirect.github.com/rust-lang/rust/pull/139224)
- [Guarantee that `{float}::NAN` is a quiet
NaN.](https://redirect.github.com/rust-lang/rust/pull/139483)

## Stabilized APIs

-
[`Cell::update`](https://doc.rust-lang.org/stable/std/cell/struct.Cell.html#method.update)
- [`impl Default for *const
T`](https://doc.rust-lang.org/nightly/std/primitive.pointer.html#impl-Default-for-*const+T)

-
[`HashSet::extract_if`](https://doc.rust-lang.org/stable/std/collections/struct.HashSet.html#method.extract_if)
-
[`proc_macro::Span::line`](https://doc.rust-lang.org/stable/proc_macro/struct.Span.html#method.line)
-
[`proc_macro::Span::column`](https://doc.rust-lang.org/stable/proc_macro/struct.Span.html#method.column)

-
[`proc_macro::Span::local_file`](https://doc.rust-lang.org/stable/proc_macro/struct.Span.html#method.local_file)

These previously stable APIs are now stable in const contexts:

-
[`NonNull<T>::replace`](https://doc.rust-lang.org/stable/std/ptr/struct.NonNull.html#method.replace)
- [`<*mut
T>::replace`](https://doc.rust-lang.org/stable/std/primitive.pointer.html#method.replace)
-
[`std::ptr::swap_nonoverlapping`](https://redirect.github.com/rust-lang/rust/pull/137280)
- [`Cell::{replace, get, get_mut, from_mut,
as_slice_of_cells}`](https://redirect.github.com/rust-lang/rust/pull/137928)

## Cargo

- [Stabilize automatic garbage
collection.](https://redirect.github.com/rust-lang/cargo/pull/14287/)
- [use `zlib-rs` for gzip compression in rust
code](https://redirect.github.com/rust-lang/cargo/pull/15417/)

## Rustdoc

- [Doctests can be ignored based on target names using `ignore-*`
attributes.](https://redirect.github.com/rust-lang/rust/pull/137096)
- [Stabilize the `--test-runtool` and `--test-runtool-arg` CLI options
to specify a program (like qemu) and its arguments to run a
doctest.](https://redirect.github.com/rust-lang/rust/pull/137096)

<a id="1.88.0-Compatibility-Notes"></a>

## Compatibility Notes

- [Finish changing the internal representation of pasted
tokens](https://redirect.github.com/rust-lang/rust/pull/124141). Certain
invalid declarative macros that were previously accepted in obscure
circumstances are now correctly rejected by the compiler. Use of a `tt`
fragment specifier can often fix these macros.
- [Fully de-stabilize the `#[bench]`
attribute](https://redirect.github.com/rust-lang/rust/pull/134273).
Usage of `#[bench]` without `#![feature(custom_test_frameworks)]`
already triggered a deny-by-default future-incompatibility lint since
Rust 1.77, but will now become a hard error.
- [Fix borrow checking some always-true
patterns.](https://redirect.github.com/rust-lang/rust/pull/139042)
The borrow checker was overly permissive in some cases, allowing
programs that shouldn't have compiled.
- [Update the minimum external LLVM to
19.](https://redirect.github.com/rust-lang/rust/pull/139275)
- [Make it a hard error to use a vector type with a non-Rust ABI without
enabling the required target
feature.](https://redirect.github.com/rust-lang/rust/pull/139309)

- [Add a warn-by-default `mismatched_lifetime_syntaxes`
lint.](https://redirect.github.com/rust-lang/rust/pull/138677)
This lint detects when the same lifetime is referred to by different
syntax categories between function arguments and return values, which
can be confusing to read, especially in unsafe code.
This lint supersedes the warn-by-default `elided_named_lifetimes` lint.

## Cargo

- [`cargo fix` and `cargo clippy --fix` now default to the same Cargo
target selection as other build
commands.](https://redirect.github.com/rust-lang/cargo/pull/15192/)
Previously it would apply to all targets (like binaries, examples,
tests, etc.). The `--edition` flag still applies to all targets.
- [Stabilize
doctest-xcompile.](https://redirect.github.com/rust-lang/cargo/pull/15462/)
Doctests are now tested when cross-compiling. Just like other tests, it
will use the [`runner`
setting](https://doc.rust-lang.org/cargo/reference/config.html#targettriplerunner)
to run the tests. If you need to disable tests for a target, you can use
the [ignore doctest
attribute](https://doc.rust-lang.org/rustdoc/write-documentation/documentation-tests.html#ignoring-targets)
to specify the targets to ignore.

<a id="1.89.0-Compatibility-Notes"></a>

## Compatibility Notes

- [Make `missing_fragment_specifier` an unconditional
error](https://redirect.github.com/rust-lang/rust/pull/128425)
- [Enabling the `neon` target feature on
`aarch64-unknown-none-softfloat` causes a
warning](https://redirect.github.com/rust-lang/rust/pull/135160) because
mixing code with and without that target feature is not properly
supported by LLVM
- [Sized Hierarchy: Part
I](https://redirect.github.com/rust-lang/rust/pull/137944)
- Introduces a small breaking change affecting `?Sized` bounds on impls
on recursive types which contain associated type projections. It is not
expected to affect any existing published crates. Can be fixed by
refactoring the involved types or opting into the `sized_hierarchy`
unstable feature. See the [FCP
report](https://redirect.github.com/rust-lang/rust/pull/137944#issuecomment-2912207485)
for a code example.
- The warn-by-default `elided_named_lifetimes` lint is [superseded by
the warn-by-default `mismatched_lifetime_syntaxes`
lint.](https://redirect.github.com/rust-lang/rust/pull/138677)
- [Error on recursive opaque types earlier in the type
checker](https://redirect.github.com/rust-lang/rust/pull/139419)
- [Type inference side effects from requiring element types of array
repeat expressions are `Copy` are now only available at the end of type
checking](https://redirect.github.com/rust-lang/rust/pull/139635)
- [The deprecated accidentally-stable
`std::intrinsics::{copy,copy_nonoverlapping,write_bytes}` are now proper
intrinsics](https://redirect.github.com/rust-lang/rust/pull/139916).
There are no debug assertions guarding against UB, and they cannot be
coerced to function pointers.
- [Remove long-deprecated

## Language

- [Split up the `unknown_or_malformed_diagnostic_attributes`
lint](https://redirect.github.com/rust-lang/rust/pull/140717). This lint
has been split up into four finer-grained lints, with
`unknown_or_malformed_diagnostic_attributes` now being the lint group
that contains these lints:
  1. `unknown_diagnostic_attributes`: unknown to the current compiler
  2. `misplaced_diagnostic_attributes`: placed on the wrong item
3. `malformed_diagnostic_attributes`: malformed attribute syntax or
options
4. `malformed_diagnostic_format_literals`: malformed format string
literal

<a id="1.90-Cargo"></a>

## Cargo

- [Add `http.proxy-cainfo` config for proxy
certs](https://redirect.github.com/rust-lang/cargo/pull/15374/)
- [Use `gix` for `cargo
package`](https://redirect.github.com/rust-lang/cargo/pull/15534/)
- [feat(publish): Stabilize multi-package
publishing](https://redirect.github.com/rust-lang/cargo/pull/15636/)

<a id="1.90-Rustdoc"></a>

## Rustdoc

- [Add ways to collapse all impl
blocks](https://redirect.github.com/rust-lang/rust/pull/141663).
Previously the "Summary" button and "-" keyboard shortcut would never
collapse `impl` blocks, now they do when shift is held
- [Display unsafe attributes with `unsafe()`
wrappers](https://redirect.github.com/rust-lang/rust/pull/143662)

<a id="1.90-Compatibility-Notes"></a>

## Compatibility Notes

- [Use `lld` by default on
`x86_64-unknown-linux-gnu`](https://redirect.github.com/rust-lang/rust/pull/140525).
See also
<https://blog.rust-lang.org/2025/09/01/rust-lld-on-1.90.0-stable/>.
- [Make `core::iter::Fuse`'s `Default` impl construct `I::default()`
internally as promised in the docs instead of always being
empty](https://redirect.github.com/rust-lang/rust/pull/140985)
- [Set `MSG_NOSIGNAL` for
`UnixStream`](https://redirect.github.com/rust-lang/rust/pull/140005)
This may change program behavior but results in the same behavior as
other primitives (e.g., stdout, network sockets).
Programs relying on signals to terminate them should update handling of
sockets to handle errors on write by exiting.
- [On Unix `std::env::home_dir` will use the fallback if the `HOME`
environment variable is
empty](https://redirect.github.com/rust-lang/rust/pull/141840)
- We now [reject unsupported `extern "{abi}"`s consistently in all
positions](https://redirect.github.com/rust-lang/rust/pull/142134). This
primarily affects the use of implementing traits on an `extern "{abi}"`
function pointer, like `extern "stdcall" fn()`, on a platform that
doesn't support that, like aarch64-unknown-linux-gnu. Direct usage of
these unsupported ABI strings by declaring or defining functions was
already rejected, so this is only a change for consistency.
- [const-eval: error when initializing a static writes to that
static](https://redirect.github.com/rust-lang/rust/pull/143084)
- [Check that the `proc_macro_derive` macro has correct arguments when
applied to the crate
root](https://redirect.github.com/rust-lang/rust/pull/143607)
