# Release Notes
Release notes for the `ommx` crate are organized by minor release line.
Each line page groups all changes leading to its initial stable release,
including alpha, beta, and release-candidate development, by user-facing topic.
Changes after that stable release are recorded as pull-request-based updates in
the final `x.y.x updates` section. New minor lines should get their own page,
such as `3.1.md`, instead of extending the previous line indefinitely.
## Release lines
- [Rust SDK 3.0.x](crate::doc::release_note::v3_0) - v3 redesign overview,
migration entry points, and 3.0-line updates.
