+
+Cargo
+-----
+- [Allow a dependency to specify both a git repository and an alternate registry.](https://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://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://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://github.com/rust-lang/rust/pull/154048)
+- [Seperate methods and associated functions in sidebar](https://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://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://github.com/rust-lang/rust/pull/149218)
+- [rustc: Stop passing `--allow-undefined` on wasm targets](https://github.com/rust-lang/rust/pull/149868)
+- [Gate the accidentally stabilized `#![reexport_test_harness_main]` attribute](https://github.com/rust-lang/rust/pull/152210)
+- [Error on return-position-impl-trait-in-traits whose types are too private](https://github.com/rust-lang/rust/pull/152543)
+- [Report the `uninhabited_static` lint in dependencies and make it deny-by-default](https://github.com/rust-lang/rust/pull/152853)
+- [Distributed builds now contain non-split debuginfo for windows-gnu](https://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://github.com/rust-lang/rust/pull/152931)
+- [Remove `-Csoft-float`](https://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://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://github.com/rust-lang/rust/pull/153041)
+- [Update the minimum external LLVM to 21](https://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://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://github.com/rust-lang/rust/pull/152941)
+- [target specs: stricter checks for LLVM ABI values, and correlate that with `cfg(target_abi)`](https://github.com/rust-lang/rust/pull/153769)
