# March 25, 2026 — v1.3.4 (API expansion)

Cinema / CineEI support and MakerNote image-ID expansion.

### New

* **`base-look-value`** — SET/GET the active user LUT slot by name on FX3, A1, A7S III, and other CineEI-capable bodies. LUT names are read back as human-readable strings (e.g. `"S-Log3"`, `"User1"`).
* **`shooting-enable`** — writable gate that mirrors the camera's shooting-enable license. Required on bodies that ship with license-based shooting.
* **`image-id-string`**, **`image-id-string-max-length`**, **`image-id-num`**, **`image-id-num-setting`** — MakerNote image-ID metadata. Embeds custom strings + incrementing numbers into JPEG/RAW MakerNote for asset tracking.
* **LUT import endpoint** — `POST /api/cameras/{id}/lut/import` — push a `.cube` LUT file from the host filesystem into one of the camera's 16 user-LUT slots.

### Docs

* New **CineEI** and **Guardrails** pages covering supported bodies, supported CineEI operations, and which properties are read-only vs writable depending on shooting mode.
* LUT management restructured into its own API section.
