 # Changelog
 
+## [0.9.1-beta15] – 2026-04-26
+
+### Fixes
+- AMS: Leere Slots werden beim Druckstart übersprungen – kein `filament runout` mehr bei unbelegten Kanälen (Issue #5)
+- AMS: Material-Typ wird jetzt korrekt aus dem Drucker-Protokoll gelesen (Feld `type` statt `material_type`)
+- AMS UI: Leere Slots werden grau und transparent dargestellt mit „Leer"-Label
+
+---
+
+## [0.9.1-beta14] – 2026-04-26
+
+### Fixes
+- Z-Achse: ▲ fährt jetzt aufwärts (Z+), ▼ abwärts (Z−) – Pfeile waren vertauscht (Issue #4)
+- Home All: korrekter axis-Code 5 – homed alle Achsen XYZ (Issue #4)
+- Neuer Button „Home XY" (axis=4) in der UI
+- Neuer Button „Motors Off" (axis turnOff) in der UI
+
+---
+
+## [0.9.1-beta13] – 2026-04-26
+
+### Fixes (Windows)
+- Self-Update / Settings-Neustart: `os.execv` funktioniert jetzt korrekt in der PyInstaller-Binary (kein doppelter Pfad als Argument mehr)
+- Kamera: `ffmpeg nicht gefunden` crasht nicht mehr – saubere 503-Antwort wenn ffmpeg nicht installiert ist
+- Reconnect-Loop: Kurzeitige leere TCP-Reads unter Windows führen nicht mehr sofort zu Reconnects
+
+### Struktur
+- `bridge/`: Bridge-Dateien aus `05_scripts/` herausgelöst
+- `tools/`: `extract_credentials.py` als eigenständiges Tool mit eigenem README
+- `_archive/`: RE-Forschungsordner, Analyse-Tools und alte Release-Checksums archiviert
+- README komplett neu: klarer 3-Schritte-Schnellstart
+

-extract_credentials.py – Extrahiert Anycubic LAN-MQTT-Credentials aus dem RAM
+extract_credentials.py – Extracts Anycubic LAN-MQTT credentials from the RAM
-des laufenden AnycubicSlicerNext-Prozesses.
+of the running AnycubicSlicerNext process.
 
-Voraussetzungen:
+Requirements:
-  - AnycubicSlicerNext läuft und ist mit dem Drucker verbunden
+  - AnycubicSlicerNext is running and connected to the printer
-  - Gleiches Benutzerkonto wie der Slicer-Prozess (kein Admin nötig)
+  - Same user account as the slicer process (no admin required)
 
-Verwendung:
+Usage:
   python3 extract_credentials.py [--write-env] [--env-file ../.env]
 
-Funktionsweise:
+How it works:
-  1. Prozess "AnycubicSlicer.exe" (Windows) bzw. "AnycubicSlicer" (Linux) finden
+  1. Find process "AnycubicSlicer.exe" (Windows) or "AnycubicSlicer" (Linux)
-  2. Speicherseiten des Prozesses durchsuchen (nur r/rw, keine Exec-Pages)
+  2. Scan memory pages of the process (only r/rw, no exec pages)
-  3. Nach MQTT-Credential-Patterns suchen:
+  3. Search for MQTT credential patterns:
        Username:  user[A-Za-z0-9]{8,12}
        Password:  [A-Za-z0-9+/]{13,18}
-       Drucker-IP: d{1,3}.d{1,3}.d{1,3}.d{1,3}
+       Printer IP: d{1,3}.d{1,3}.d{1,3}.d{1,3}
-  4. Kandidaten nach Plausibilität filtern und ausgeben
+  4. Filter candidates by plausibility and print results
-  5. Optional: .env-Datei schreiben
+  5. Optionally write .env file
