Some macros emit bindings with type `()` with user-provided spans, which means that this lint will warn for user code. - [Remove x86\_64-sun-solaris target.](https://togithub.com/rust-lang/rust/pull/118091/) - [Remove asmjs-unknown-emscripten target](https://togithub.com/rust-lang/rust/pull/117338/) - [Report errors in jobserver inherited through environment variables](https://togithub.com/rust-lang/rust/pull/113730/) This [may warn](https://togithub.com/rust-lang/rust/issues/120515) on benign problems too. - [Update the minimum external LLVM to 16.](https://togithub.com/rust-lang/rust/pull/117947/) - [Improve `print_tts`](https://togithub.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. - [Make `IMPLIED_BOUNDS_ENTAILMENT` into a hard error from a lint](https://togithub.com/rust-lang/rust/pull/117984/) - [Vec's allocation behavior was changed when collecting some iterators](https://togithub.com/rust-lang/rust/pull/110353) Allocation behavior is currently not specified, nevertheless changes can be surprising.
