This can cause closures to capture values that they previously wouldn't. - `mut ref` and `mut ref mut` patterns, part of the unstable [Match Ergonomics 2024 RFC](https://redirect.github.com/rust-lang/rust/issues/123076), were accidentally allowed on stable within struct pattern field shorthand. These patterns are now correctly feature-gated as unstable in this position. - [Add future-compatibility warning for derive helper attributes which conflict with built-in attributes](https://redirect.github.com/rust-lang/rust/pull/151152) - [JSON target specs](https://doc.rust-lang.org/rustc/targets/custom.html) have been destabilized and now require `-Z unstable-options` to use. Previously, they could not be used without the standard library, which has no stable build mechanism. In preparation for the `build-std` project adding that support, JSON target specs are being proactively gated to ensure they remain unstable even if `build-std` is stabilized. Cargo now includes the `-Z json-target-spec` CLI flag to automatically pass `-Z unstable-options` to the compiler when needed.
