| 109 | +- [Enable by default the `LSX` target feature for LoongArch Linux targets](https://github.com/rust-lang/rust/pull/132140) |
| 110 | +- [The unstable `-Zprofile` flag (“gcov-style” coverage instrumentation) has been removed.](https://github.com/rust-lang/rust/pull/131829) This does not affect the stable flags for coverage instrumentation (`-Cinstrument-coverage`) and profile-guided optimization (`-Cprofile-generate`, `-Cprofile-use`), which are unrelated and remain available. |
| 111 | +- Support for the target named `wasm32-wasi` has been removed as the target is now named `wasm32-wasip1`. This completes the [transition](https://github.com/rust-lang/compiler-team/issues/607) [plan](https://github.com/rust-lang/compiler-team/issues/695) for this target following [the introduction of `wasm32-wasip1`](https://github.com/rust-lang/rust/pull/120468) in Rust 1.78. Compiler warnings on [use of `wasm32-wasi`](https://github.com/rust-lang/rust/pull/126662) introduced in Rust 1.81 are now gone as well as the target is removed. |
| 112 | +- [The syntax `&pin (mut|const) T` is now parsed as a type which in theory could affect macro expansion results in some edge cases](https://github.com/rust-lang/rust/pull/130635#issuecomment-2375462821) |
| 113 | +- [Legacy syntax for calling `std::arch` functions is no longer permitted to declare items or bodies (such as closures, inline consts, or async blocks).](https://github.com/rust-lang/rust/pull/130443#issuecomment-2445678945) |
| 114 | +- [Declaring functions with a calling convention not supported on the current target now triggers a hard error](https://github.com/rust-lang/rust/pull/129935) |
| 115 | +- [The next-generation trait solver is now enabled for coherence, fixing multiple soundness issues](https://github.com/rust-lang/rust/pull/130654) |
