Compatibility Notes
-------------------

- [Raise minimum supported Apple OS versions](https://github.com/rust-lang/rust/pull/104385/)
- [make Cell::swap panic if the Cells partially overlap](https://github.com/rust-lang/rust/pull/114795/)
- [Reject invalid crate names in `--extern`](https://github.com/rust-lang/rust/pull/116001/)
- [Don't resolve generic impls that may be shadowed by dyn built-in impls](https://github.com/rust-lang/rust/pull/114941/)
- [The new `impl From<{&,&mut} [T; N]> for Vec<T>` is known to cause some inference failures with overly-generic code.](https://github.com/rust-lang/rust/issues/117054) In those examples using the `tui` crate, the combination of `AsRef<_>` and `Into<Vec>` leaves the middle type ambiguous, and the new `impl` adds another possibility, so it now requires an explicit type annotation.
