+- [Stabilize default_alloc_error_handler](https://github.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://github.com/rust-lang/rust/pull/105795/)

+<a id="1.67.0-Compatibility-Notes"></a>
+
+Compatibility Notes
+-------------------
+
+- [The layout of `repr(Rust)` types now groups m\*2^n-sized fields with
+  equivalently aligned ones.](https://github.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://github.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://github.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://github.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://github.com/rust-lang/rust/pull/105405/)
+- [`main` is now mangled as `__main_void` on `wasm32-wasi`.](https://github.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://github.com/rust-lang/cargo/pull/10592)
+

+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.

+- [Rewrite LLVM's archive writer in Rust.](https://github.com/rust-lang/rust/pull/97485/)
