+
+Compatibility Notes
+-------------------
+- [Add allow-by-default lint for unit bindings](https://github.com/rust-lang/rust/pull/112380/)
+  This is expected to be upgraded to a warning by default in a future Rust
+  release. Some macros emit bindings with type `()` with user-provided spans,
+  which means that this lint will warn for user code.
+- [Properly reject `default` on free const items](https://github.com/rust-lang/rust/pull/117818/)
+- [Report errors in jobserver inherited through environment variables](https://github.com/rust-lang/rust/pull/113730/)
+- [Update the minimum external LLVM to 16.](https://github.com/rust-lang/rust/pull/117947/)
+- [Remove now deprecated target x86_64-sun-solaris.](https://github.com/rust-lang/rust/pull/118091/)
+- [Improve `print_tts`](https://github.com/rust-lang/rust/pull/114571/)
+  This change can break some naive manual parsing of token trees in proc macro
+  code which expect a particular structure after `.to_string()`, rather than just arbitrary Rust code.
+- [Remove asmjs](https://github.com/rust-lang/rust/pull/117338/)
+- [Make `IMPLIED_BOUNDS_ENTAILMENT` into a hard error from a lint](https://github.com/rust-lang/rust/pull/117984/)
+
+Maybe:
+- [rustc_llvm: Link to libkstat on Solaris/SPARC](https://github.com/rust-lang/rust/pull/114224/)
+- [Pass +forced-atomics feature for riscv32{i,im,imc}-unknown-none-elf](https://github.com/rust-lang/rust/pull/114499/)
+- [Remove legacy bitcode defaults from all Apple specs](https://github.com/rust-lang/rust/pull/117364/)

+Internal Changes
+----------------
