### Details
- <a id="details-001"></a>**0.0.1**: Initial published crate; dependency-free, always `#![no_std]`; edition 2021; APIs limited to constructor, accessors, `into_parts`, and tuple-to-envelope conversion; traits derive `Debug + Clone + PartialEq + Eq + Hash` when fields support them.
Guidance:
- Add rows as new versions land; note whether they remain supported or receive backports.
- If multiple lines are maintained (e.g., 0.1.x vs 0.2.x), record cross-compatibility and deprecation timelines here.
