- Cargo enhancements: new include config key, pubtime field in registry index, support for TOML v1.1 manifests, and making cargo-bin executables available at runtime.
- Compatibility-breaking changes: stricter lifetime bounds for dyn types, revised closure capture semantics, macros now imported via prelude leading to ambiguous import warnings, and changes to include! shebang handling.
