 # 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
-- **Fortschritts-Karte:** Verstrichen / Slicer-Schätzung / Restzeit als Mini-Cards (gleicher Stil wie Temperaturkarten)
+- **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
-- **Layer-Mini-Card:** Layerzahl als Mini-Card neben der Fortschrittsleiste
+- **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
-- **Slicer-Schätzzeit:** OrcaSlicer schreibt die geschätzte Zeit ans Ende der GCode-Datei — Bridge liest jetzt auch die letzten 64 KB (vorher nur die ersten 16 KB)
+- **file_ready-Banner:** Upload-Banner wird nach Stopp oder Abbruch eines Drucks nicht mehr angezeigt
-- **start.sh:** `config/`-Verzeichnis wird jetzt automatisch erstellt und `config.ini.example` wird beim ersten Start hineinkopiert (Issue #15)
+- **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)

 # 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
-- **Progress card:** Elapsed / Slicer estimate / Remaining time shown as mini-cards (same style as temperature cards)
+- **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
-- **Layer mini-card:** Layer count displayed as mini-card next to the progress bar
+- **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
-- **Slicer estimate time:** OrcaSlicer writes the estimated time at the end of the GCode file — bridge now also scans the last 64 KB (previously only the first 16 KB were checked)
+- **file_ready banner:** Upload banner is no longer shown after print stop or cancel
-- **start.sh:** `config/` directory is now created automatically and `config.ini.example` is copied into it on first run (Issue #15)
+- **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)
