 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.
-- [Proc-macro derives using inaccessible names from parent modules is now a hard error.](https://github.com/rust-lang/rust/pull/84022/)
-  This has been a warning since 1.29.0, and denied by default since 1.58.0.
-  (**TODO**: revert proposed in <https://github.com/rust-lang/rust/pull/107133>)
 - [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/)
