121- `mut ref` and `mut ref mut` patterns, part of the unstable [Match Ergonomics 2024 RFC](https://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.

123▶- [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. See [#150151](https://github.com/rust-lang/rust/pull/150151), [#151534](https://github.com/rust-lang/rust/pull/150151), and [rust-lang/cargo#16557](https://github.com/rust-lang/cargo/pull/16557).

221- Stabilize the config include key. The top-level include config key allows loading additional config files, enabling better organization, sharing, and management of Cargo configurations across projects and environments. [docs](https://doc.rust-lang.org/nightly/cargo/reference/config.html#including-extra-configuration-files) [#16284](https://github.com/rust-lang/cargo/pull/16284)
222- Stabilize the pubtime field in registry index. This records when a crate version was published and enables time-based dependency resolution in the future. Note that crates.io will gradually backfill existing packages when a new version is published. Not all crates have pubtime yet.

223▶- Cargo now parses [TOML v1.1](https://toml.io/en/v1.1.0) for manifests and configuration files. Note that using these features in Cargo.toml will raise your development MSRV, but the published manifest remains compatible with older parsers.
