+
+Compatibility Notes
+-------------------
+- [Rust now raises an error for macro invocations inside the `#![crate_name]` attribute](https://github.com/rust-lang/rust/pull/127581)
+- [Unstable fields are now always considered to be inhabited](https://github.com/rust-lang/rust/pull/133889)
+- [Macro arguments of unary operators followed by open beginning ranges may now be matched differently](https://github.com/rust-lang/rust/pull/134900)
+- [Make `Debug` impl of raw pointers print metadata if present](https://github.com/rust-lang/rust/pull/135080)
+- [Warn against function pointers using unsupported ABI strings in dependencies](https://github.com/rust-lang/rust/pull/135767)
+- [Associated types on `dyn` types are no longer deduplicated](https://github.com/rust-lang/rust/pull/136458)
+- [Forbid attributes on `..` inside of struct patterns (`let Struct { #[attribute] .. }) =`](https://github.com/rust-lang/rust/pull/136490)
+- [Make `ptr_cast_add_auto_to_object` lint into hard error](https://github.com/rust-lang/rust/pull/136764)
+- Many `std::arch` intrinsics are now safe to call in some contexts, there may now be new `unused_unsafe` warnings in existing codebases.
+- [Limit `width` and `precision` formatting options to 16 bits on all targets](https://github.com/rust-lang/rust/pull/136932)
+- [Turn order dependent trait objects future incompat warning into a hard error](https://github.com/rust-lang/rust/pull/136968)
+- [Denote `ControlFlow` as `#[must_use]`](https://github.com/rust-lang/rust/pull/137449)
+- [Windows: The standard library no longer links `advapi32`, except on win7.](https://github.com/rust-lang/rust/pull/138233) Code such as C libraries that were relying on this assumption may need to explicitly link advapi32.
+- [Proc macros can no longer observe expanded `cfg(true)` attributes.](https://github.com/rust-lang/rust/pull/138844)
+- [Start changing the internal representation of pasted tokens](https://github.com/rust-lang/rust/pull/124141). Certain invalid declarative macros that were previously accepted in obscure circumstances are now correctly rejected by the compiler. Use of a `tt` fragment specifier can often fix these macros.
+- [Don't allow flattened format_args in const.](https://github.com/rust-lang/rust/pull/139624)

+significant improvements to the performance or internals of rustc and related
+tools.
