 # Changelog
 
+## [0.9.7] – 2026-05-08
+
+### Neu
+- **fetch_credentials-Tool:** Ruft MQTT-Credentials direkt vom Drucker per HTTP ab — kein laufender Anycubic Slicer nötig, nur die Drucker-IP. Linux-Binary und Windows-EXE im Release enthalten. (Beitrag von bebu, PR #19)
+
+### Fixes
+- **Upload großer GCode-Dateien:** Dateien >1 MB wurden mit HTTP 413 abgelehnt — aiohttp `client_max_size` auf 256 MB erhöht
+- **Upload-Timeout:** Socket-Timeout nach GCode-Upload von 10s auf 120s erhöht — große Dateien führten zu einem Absturz der Bridge mit leerer Antwort während der Drucker noch verarbeitete
+
+---
+
+## [0.9.6] – 2026-05-02
+
+### Neu
+- **Licht-Status-Synchronisierung:** Ein/Aus-Zustand und Helligkeit des Druckerlichts werden jetzt live über `light/report` MQTT gelesen — der Licht-Toggle in der UI spiegelt den echten Druckerstatus wider
+- **Zeit-Minicards:** Fortschritts-Panel zeigt jetzt drei Karten — Verstrichen, Restzeit und Slicer-Schätzung — sowie einen Layer-Badge neben dem Fortschrittsbalken
+- **Slicer-Schätzzeit aus GCode:** Geschätzte Druckzeit wird direkt aus der hochgeladenen GCode-Datei gelesen (OrcaSlicer: `; total estimated time:` am Dateiende, PrusaSlicer: `; estimated printing time` im Header)
+- **Erweiterte Druckerstatus-Strings:** `pausing`, `paused`, `resuming`, `resumed`, `stopping`, `stopped` hinzugefügt — fehlten bisher und ließen die UI rohe Status-Codes bei Pause/Fortsetzen/Stopp anzeigen
+
+### Fixes
+- **file_ready-Banner:** Upload-Banner wird nach Stopp oder Abbruch eines Drucks nicht mehr angezeigt
+- **Zeitanzeige bei Stopp/Abbruch:** Verstrichen-, Restzeit- und Slicer-Schätzung werden auf null zurückgesetzt wenn ein Druck gestoppt oder abgebrochen wird
+- **start.sh:** `config/`-Verzeichnis und `config.ini.example` werden beim ersten Start automatisch angelegt wenn sie fehlen (Issue #15)
+
+---
+
+## [0.9.5] – 2026-05-01
+
+### Neu
+- **Upload-Banner:** Nach „Nur hochladen" erscheint ein grüner Banner mit Dateiname — „▶ Druck starten" startet den Druck direkt, „✕ Abbrechen" schließt den Banner
+
+### Fixes
+- **Auto-Print:** `auto_print` wurde nach dem Multipart-Loop immer auf `False` zurückgesetzt — OrcaSlicer „Hochladen und drucken" startete den Druck nie automatisch
+- **Thumbnail:** Vorschaubild wird jetzt auch bei „Nur hochladen" angezeigt — Bridge fragt `fileDetails` direkt nach dem Upload an
+- **Log Auto-Scroll:** Scroll-Position bleibt erhalten wenn Auto-Scroll deaktiviert ist — kein ungewollter Sprung nach oben mehr
+
+---
+
+## [0.9.4] – 2026-05-01
+
+### Neu
+- **AMS-Slot-Editor:** Slot im AMS-Panel anklicken → Dialog mit Farbpicker und Material-Auswahl (Schnellbuttons: PLA/PETG/ABS/ASA/TPU/PA/PC/HIPS oder Freitext) direkt im Browser
+- **Verbessertes Log-Panel:** Vollständige MQTT-Payloads (keine Kürzung mehr), Richtungsfilter (Alle/RX/TX) und Topic-Schnellfilter (AMS / print / info / status)
+
+### Fixes
+- **i18n:** Kamera-Placeholder-Text und Log-Richtungs-Button „Alle" werden jetzt korrekt beim Sprachwechsel übersetzt
+
+---
+
+## [0.9.3] – 2026-05-01
+
+### Fixes
+- **Update-Check:** Stable-User erhalten keine Dev-Pre-Releases mehr — `STABLE_RELEASE_API` hatte `pre-release=true`, wodurch stabile Installationen Dev-Builds statt stabiler Releases fanden (Issue #14)
+- **Version nach Update:** `VERSION`-Datei wird jetzt im Docker-Image mitgeliefert (`COPY VERSION .`) — `_write_version()` benötigt eine vorhandene Datei, ohne die wurde die Version nach dem Self-Update nie aktualisiert (Issue #14)
+
+### Neu
+- **Version im Header:** Laufende Version wird im Web-UI-Header neben dem Druckernamen angezeigt — kein Öffnen der Einstellungen nötig (Issue #14)
+

 # Changelog
 
+## [0.9.7] – 2026-05-08
+
+### New
+- **fetch_credentials tool:** Fetches and decrypts MQTT credentials directly from the printer via HTTP — no running Anycubic Slicer required, only the printer IP needed. Linux binary and Windows EXE included in release. (Contributed by bebu, PR #19)
+
+### Fixes
+- **Large GCode upload:** Files >1 MB were rejected with HTTP 413 — aiohttp `client_max_size` raised to 256 MB
+- **Upload timeout:** Socket timeout after GCode upload raised from 10s to 120s — large files caused the bridge to crash with an empty response while the printer was still processing
+
+---
+
+## [0.9.6] – 2026-05-02
+
+### New
+- **Light status sync:** Light on/off state and brightness are now read live from the printer via `light/report` MQTT message — the light toggle in the UI reflects the actual printer state
+- **Time mini-cards:** Progress panel now shows three cards — Elapsed, Remaining and Slicer estimate — with a layer counter badge next to the progress bar
+- **Slicer estimate from GCode:** Estimated print time is parsed directly from the uploaded GCode file (OrcaSlicer: `; total estimated time:` at end of file, PrusaSlicer: `; estimated printing time` in header)
+- **Extended printer status strings:** Added `pausing`, `paused`, `resuming`, `resumed`, `stopping`, `stopped` states — previously missing, causing the UI to show raw status codes during pause/resume/stop transitions
+
+### Fixes
+- **file_ready banner:** Upload banner is no longer shown after print stop or cancel
+- **Timers on stop/cancel:** Elapsed, remaining and slicer estimate times are reset to zero when a print is stopped or cancelled
+- **start.sh:** `config/` directory and `config.ini.example` are now created automatically on first run if missing (Issue #15)
+
+---
+
+## [0.9.5] – 2026-05-01
+
+### New
+- **Upload banner:** After "Upload only", a green banner appears with the filename — "▶ Start Print" starts the print directly, "✕ Cancel" dismisses the banner
+
+### Fixes
+- **Auto-print:** `auto_print` was always reset to `False` after the multipart loop — OrcaSlicer "Upload and print" never started the print automatically
+- **Thumbnail:** Preview image is now shown after "Upload only" — bridge requests `fileDetails` immediately after upload
+- **Log auto-scroll:** Scroll position is preserved when auto-scroll is disabled — no more unwanted jump to top
+
+---
+
+## [0.9.4] – 2026-05-01
+
+### New
+- **AMS slot editor:** Click any slot in the AMS panel to open an edit dialog — set color (color picker) and material (preset buttons: PLA/PETG/ABS/ASA/TPU/PA/PC/HIPS or free text) directly from the browser
+- **Improved log panel:** Full MQTT payloads (no truncation), direction filter (All/RX/TX) and topic quick-filter buttons (AMS / print / info / status)
+
+### Fixes
+- **i18n:** Camera placeholder text and log direction "All" button now correctly translated on language switch
+
+---
+
+## [0.9.3] – 2026-05-01
+
+### Fixes
+- **Update check:** Stable users no longer receive dev pre-releases — `STABLE_RELEASE_API` had `pre-release=true` which caused stable installs to find dev builds instead of stable releases (Issue #14)
+- **Version after update:** `VERSION` file is now included in the Docker image (`COPY VERSION .`) — `_write_version()` requires the file to exist, without it the version was never updated after self-update (Issue #14)
+
+### New
+- **Version in header:** Running version shown in the Web-UI header next to the printer name — no need to open Settings to check (Issue #14)
