<a id="1.96.0-Cargo"></a>

## Cargo

- [Allow a dependency to specify both a git repository and an alternate
registry.](https://redirect.github.com/rust-lang/cargo/pull/16810/) Just
like with crates.io, the git repository will be used locally, but the
registry version will be used when published.
- [Added `target.'cfg(..)'.rustdocflags` support in
configuration.](https://redirect.github.com/rust-lang/cargo/pull/16846)
- Fixed
[CVE-2026-5222](https://blog.rust-lang.org/2026/05/25/cve-2026-5222/)
and
[CVE-2026-5223](https://blog.rust-lang.org/2026/05/25/cve-2026-5223/).

<a id="1.96-Rustdoc"></a>

## Rustdoc

- [Deprecation notes are now rendered like any other
documentation](https://redirect.github.com/rust-lang/rust/pull/149931).
Previously they used the css `white-space: pre-wrap;` property and
stripped any `<p>` elements from the rendered html, however this caused
issues and unintuitive behavior. The new behavior should be more
predictable, however some multi-line deprecation notes will now be
rendered as as single lines. If this is undesirable, you can use the
standard markdown method of forcing a linebreak, which is two spaces
followed by a newline (`"\n"`).
- [Don't emit rustdoc `missing_doc_code_examples` lint on impl
items](https://redirect.github.com/rust-lang/rust/pull/154048)
- [Seperate methods and associated functions in
sidebar](https://redirect.github.com/rust-lang/rust/pull/154644)

<a id="1.96.0-Compatibility-Notes"></a>

## Compatibility Notes

- [Fix layout of `#[repr(Int)]` enums in some edge cases involving
fields of uninhabited zero-sized
types](https://redirect.github.com/rust-lang/rust/pull/146989)
- [Prevent unsize-coercing into `Pin<Foo>` where `Foo` doesn't implement
`Deref`. Some such coercions were previously allowed, but produce a type
with no useful public
API.](https://redirect.github.com/rust-lang/rust/pull/149218)
- [rustc: Stop passing `--allow-undefined` on wasm
targets](https://redirect.github.com/rust-lang/rust/pull/149868)
- [Gate the accidentally stabilized `#![reexport_test_harness_main]`
attribute](https://redirect.github.com/rust-lang/rust/pull/152210)
- [Error on return-position-impl-trait-in-traits whose types are too
private](https://redirect.github.com/rust-lang/rust/pull/152543)
- [Report the `uninhabited_static` lint in dependencies and make it
deny-by-default](https://redirect.github.com/rust-lang/rust/pull/152853)
- [Distributed builds now contain non-split debuginfo for
windows-gnu](https://redirect.github.com/rust-lang/rust/pull/152870)
This appears to improve the quality of backtraces. This change has no
effect on the defaults for the output of rustc/cargo on these targets.
- [Check const generic arguments are correctly typed in more
positions](https://redirect.github.com/rust-lang/rust/pull/152931)
- [Remove
`-Csoft-float`](https://redirect.github.com/rust-lang/rust/pull/152973)
- [Importing structs with `::{self [as name]}`, e.g., `struct S {}; use
S::{self as Other};`, is now no longer permitted because `{self}`
imports require a module
parent.](https://redirect.github.com/rust-lang/rust/pull/152996)
- [For `export_name`, `link_name`, and `link_section` attributes, if
multiple of the same attribute is present, the first one now takes
precedence.](https://redirect.github.com/rust-lang/rust/pull/153041)
- [Update the minimum external LLVM to
21](https://redirect.github.com/rust-lang/rust/pull/153684)
- On `avr` targets, C's `double` type is 32-bit by default, so [change
`c_double` to `f32` on `avr` targets to
match](https://redirect.github.com/rust-lang/rust/pull/154647). This is
a breaking change, but necessary to make `c_double` match C's double.

## 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.

- [JSON targets: `aarch64` softfloat targets now have to have
`rustc_abi` set to
`"softfloat"`](https://redirect.github.com/rust-lang/rust/pull/152941)
- [target specs: stricter checks for LLVM ABI values, and correlate that
with
`cfg(target_abi)`](https://redirect.github.com/rust-lang/rust/pull/153769)
