| 71 | +Compatibility Notes |
| 72 | +------------------- |
| 73 | + |
| 74 | +- [The layout of `repr(Rust)` types now groups m\*2^n-sized fields with |
| 75 | + equivalently aligned ones.](https://github.com/rust-lang/rust/pull/102750/) |
| 76 | + This is intended to be an optimization, but it is also known to increase type |
| 77 | + sizes in a few cases for the placement of enum tags. As a reminder, the layout |
| 78 | + of `repr(Rust)` types is an implementation detail, subject to change. |
| 79 | +- [0.5 now rounds to 0 when formatted to 0 decimal places.](https://github.com/rust-lang/rust/pull/102935/) |
| 80 | + This makes it consistent with the rest of floating point formatting that |
| 81 | + rounds ties toward even digits. |
| 82 | +- [Chains of `&&` and `||` will now drop temporaries from their sub-expressions in |
| 83 | + evaluation order, left-to-right.](https://github.com/rust-lang/rust/pull/103293/) |
| 84 | + Previously, it was "twisted" such that the _first_ expression dropped its |
| 85 | + temporaries _last_, after all of the other expressions dropped in order. |
| 86 | +- [Underscore suffixes on string literals are now a hard error.](https://github.com/rust-lang/rust/pull/103914/) |
| 87 | + This has been a future-compatibility warning since 1.20.0. |
| 88 | +- [Stop passing `-export-dynamic` to `wasm-ld`.](https://github.com/rust-lang/rust/pull/105405/) |
| 89 | +- [`main` is now mangled as `__main_void` on `wasm32-wasi`.](https://github.com/rust-lang/rust/pull/105468/) |
| 90 | +- [Cargo now emits an error if there are multiple registries in the configuration |
| 91 | + with the same index URL.](https://github.com/rust-lang/cargo/pull/10592) |

| 113 | +-------- |

| 125 | +- [Trigger `must_use` on `impl Trait` for supertraits](https://github.com/rust-lang/rust/pull/102287/) |

| 131 | +- [Opaque types no longer imply lifetime bounds](https://github.com/rust-lang/rust/pull/95474/) |
| 132 | + This is a soundness fix which may break code that was erroneously relying on this behavior. |

| 135 | +-------- |
