# Changelog

All notable changes to this crate are documented here. The format
follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/) and
this project adheres to [Semantic Versioning](https://semver.org/).

## 0.1.0 — 2026-04-13

Initial release. The DongLoRa wire-protocol types and COBS framing,
extracted from the firmware so the firmware, `client-rs`, `mux-rs`,
and `bridge` can share one definition.

### Added

- Wire types: `Command`, `Response`, `RadioConfig`, `Bandwidth`,
  `ErrorCode`, plus the `MAX_PAYLOAD`, `RADIO_CONFIG_SIZE`,
  `TX_POWER_MAX`, and `PREAMBLE_DEFAULT` constants. Fixed-width
  little-endian on the wire — see the firmware repo's `PROTOCOL.md`.
- `framing` module: streaming `CobsDecoder` plus `cobs_encode_response`,
  with a `MAX_FRAME` constant sized to fit any valid `Response` after
  COBS overhead.
- Cargo features: `defmt` (default, derives `defmt::Format` on public
  enums) and `std` (off, opt-in for host-side `Debug` niceties).
- Test surface: 23 proptest properties (~1.13M cases per run), 4
  cargo-fuzz targets, 16 canonical wire-byte vectors anchored to the
  spec, 6 mutation-killers. Mutation testing reaches 89/89 viable
  mutants under both feature configurations (3 provably-equivalent
  mutants documented and excluded). Miri runs clean on the library
  and the canonical-vector tests.
- `forbid(unsafe_code)` at the crate root.
- GitHub Actions CI (test/clippy/fmt/doc/deny/miri/fuzz/mutants).
