 # Changelog
 
+## [0.9.6.1] – 2026-05-02
+
+### Fixes
+- **Upload-Banner:** Banner wird nach Stopp/Abbruch nicht mehr erneut angezeigt — `file_ready` und Thumbnail werden jetzt gecleared wenn der Drucker `stoped` oder `canceled` meldet
+
+---
+
+## [0.9.6] – 2026-05-02
+
+### Neu
+- **Fortschritts-Karte:** Verstrichen / Slicer-Schätzung / Restzeit als Mini-Cards (gleicher Stil wie Temperaturkarten)
+- **Layer-Mini-Card:** Layerzahl als Mini-Card neben der Fortschrittsleiste
+
+### 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)
+- **start.sh:** `config/`-Verzeichnis wird jetzt automatisch erstellt und `config.ini.example` wird beim ersten Start hineinkopiert (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

 # Changelog
 
+## [0.9.6.1] – 2026-05-02
+
+### Fixes
+- **Upload banner:** Banner is no longer shown again after print stop/cancel — `file_ready` and thumbnail are now cleared when the printer reports `stoped` or `canceled`
+
+---
+
+## [0.9.6] – 2026-05-02
+
+### New
+- **Progress card:** Elapsed / Slicer estimate / Remaining time shown as mini-cards (same style as temperature cards)
+- **Layer mini-card:** Layer count displayed as mini-card next to the progress bar
+
+### 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)
+- **start.sh:** `config/` directory is now created automatically and `config.ini.example` is copied into it on first run (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

+Decrypt printer configuration data using AES-256-CBC
+
+This script decrypts encrypted printer configuration data from a 3D printer using AES-256-CBC. 
+The method was reverse engineered from the vue project embedded in libWorkbench.so, 
+which is part of Anycubic Slicer Next. 
+The decryption key is derived from the device token, 
+and the IV is obtained from the response token in the encrypted data.
+
+- Algorithm: AES-256-CBC
+- Key: Characters 16-32 of the token from info.json
+- IV: The response token from ctrl.json
+- Mode: CBC with PKCS7 padding
+
+Usage:
+    python3 fetch_credentials.py --ip 192.168.2.32
+    python3 fetch_credentials.py --ip 192.168.2.32 --port 18910
