# Changelog
All notable changes to this project are documented in this file.
The format is based on Keep a Changelog and this project uses Semantic Versioning.
## [0.1.8] - 2026-03-07
### Added
- Root URL now serves a built-in printer web interface for Home Assistant with status, info, text printing, and image upload printing.
### Changed
- Swagger docs remain available under `/docs` while the Home Assistant "Open" action now lands on the print UI.
## [0.1.7] - 2026-03-07
### Fixed
- Home Assistant ingress docs now use a custom Swagger UI route with a relative `openapi.json` URL, avoiding `404 /openapi.json` behind ingress prefixes.
### Changed
- Home Assistant add-on now requests `full_access: true` in addition to Bluetooth capabilities to unblock Classic RFCOMM socket access on stricter hosts.
## [0.1.6] - 2026-03-07
### Added
- Added this `CHANGELOG.md` and established a release policy to update version and changelog for every change.
## [0.1.5] - 2026-03-07
### Changed
- Home Assistant add-on now requests `NET_RAW` in addition to `NET_ADMIN` for Classic Bluetooth RFCOMM sockets.
- Add-on documentation updated with Classic permission requirements.
## [0.1.4] - 2026-03-07
### Fixed
- RFCOMM connection under `uvloop` now uses direct Bluetooth socket connect in a worker thread, avoiding address-family resolution issues.
- Classic Bluetooth socket errors are mapped to API-safe printer errors instead of unhandled 500s.
## [0.1.3] - 2026-03-07
### Changed
- Home Assistant add-on metadata updated for ingress/web UI access.
- API root endpoint now redirects to docs in an ingress-compatible way.
- Added attribution for original upstream project and AI-assisted extension note.

The [Fichero](https://www.action.com/nl-nl/p/3212141/fichero-labelprinter/) is a cheap Bluetooth thermal label printer sold at Action. Internally it's an AiYin D11s made by Xiamen Print Future Technology. The official app is closed-source and doesn't expose the protocol, so this project reverse-engineers it from the decompiled APK.
