## [Unreleased]

## [1.4.0] — 2026-07-30

- fix: `master.Node.Diagnostics` now transmits LIN diagnostic frames
(0x3C/0x3D) with the classic checksum required by ISO 17987 / LIN 2.x
§4.2.3, instead of the enhanced checksum every other frame uses; added
a checksum-type-aware `Bus.PublishFrame` and routed `Diagnostics`
through it (#72)
- fix: `linNode.Send`/`virtual.Bus.Publish` now return
`lin.ErrPayloadTooLarge` for a payload exceeding `LINMaxDataLen`
instead of silently accepting it (#72)
- fix: `linNode.Send` now returns `lin.ErrInvalidFrame` (previously
`ErrNotConnected`) for a malformed/out-of-range message ID, matching
`FromMessage` (#72)
- fix(safety): recomputed every HARA hazard's `asil` in `.fusa-hara.json`
from its severity/exposure/controllability fields — all six were one
band too high (#72)
- test: `TestDiagnostics_requestResponseRoundTrip` now asserts checksum
type/value on both the 0x3C request and 0x3D response frames (#72)
- chore: replaced internal uses of the deprecated `lin.MaxID`/
`lin.MaxDataLen` aliases with `LINMaxID`/`LINMaxDataLen` (#72)
- docs: `HARA.md` SG-02 now traces to the checksum requirements
(`REQ-LIN-008/009/010`) instead of the PID-parity requirement (#72)
- docs: `sas.md` no longer reports `SVP.md`/`SCMP.md`/`SQAP.md` as
missing — all three exist at the repo root (#72)
- docs: removed a `CONTRIBUTING.md` project-structure row for a
nonexistent `transport/` directory (#72)

## [1.3.0] — 2026-07-27

- fix: `virtual.Bus.CloseWithDrain` now returns `lin.ErrTimeout` (and counts
