+## 0.6.3-3 (2026-04-17)
+- Enable Core API access (`homeassistant_api: true`) so the addon can call HA Core's `update.install` service. Required for in-app self-update — Supervisor blocks `/store/addons/<self>/update`, so the backend routes through Core.
+
 ## 0.6.3-2 (2026-04-15)
 - Remove the `TZ` add-on option. Application timezone is now auto-derived in the Web UI from the station location (latitude/longitude) via `timezonefinder`, so a separately-configured container `TZ` only ever duplicated — and occasionally conflicted with — the UI-derived zone. All app-facing timestamps (dashboard, API responses, database) and Python service stdout (`api`/`main`/`birdnet`) already honor the UI-derived zone via the logging formatter; the frontend log viewer also re-converts Icecast timestamps on read. Net effect in the HA addon log pane: Python logs keep their local-time timestamps; only Icecast's raw stdout now prints in UTC — an intentional trade for a single source of truth. Deletes the now-redundant `rootfs/etc/cont-init.d/02-timezone.sh` added in 0.5.6-2.
 - Clean up the options YAML in DOCS.md and README.md. Removed `RECORDING_MODE` and `RTSP_URL` — these were documented as addon options but never wired: the app reads them from `user_settings.json` (configured via the Web UI), not from env vars. Also dropped `http_stream` from the list of modes (only `pulseaudio` and `rtsp` remain in `backend/config/constants.py`). Moved `STREAM_BITRATE` under an `env_vars:` example since it's honored by `start-icecast.sh` but has never been a first-class option in the schema.
