+# Changelog
+
+## [0.9.1-beta14] – 2026-04-26
+
+### Fixes
+- Z-Achse: ▲ fährt jetzt aufwärts (Z+), ▼ abwärts (Z−) – Pfeile waren vertauscht (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

+
+---
+
+## [0.9.1-beta12] – 2026-04-25
+
+### Fixes

+
+---
+
+## [0.9.1-beta11] – 2026-04-25
+
+### Fixes
+- Drucker-IP wird automatisch bereinigt wenn der Nutzer versehentlich den Port miteingibt (z.B. `192.168.1.102:9883` → `192.168.1.102`)
+- Settings-Modal: Hinweis erscheint wenn ein `:` in der IP erkannt wird
+- `docker-compose.yml`: `.env` wird als Volume in den Container gemountet – Einstellungen bleiben nach `docker-compose restart` erhalten
+
+---
+
+## [0.9.1-beta10] – 2026-04-25
+
+### Neu
+- `start.sh` – startet die Bridge per Docker, baut das Image automatisch beim ersten Aufruf

+- README: LAN-Modus korrekt als Drucker-Menüoption beschrieben (kein WLAN-Bezug)
+- README: Versionsnummer wird ab jetzt automatisch bei jedem Release aktualisiert
+- `extract_credentials`: kein `--write-env` mehr empfohlen – Werte im ⚙-Menü eintragen
+- Dockerfile im Release-Repo: Pfade ohne `05_scripts/`-Präfix (direkt aus Repo-Root)
+- `release.sh`: Dockerfile für Release-Repo automatisch per `sed` angepasst
+
+### Fixes
+- Restdruckzeit (`remain_time`) wird jetzt korrekt aus `print/report` übernommen und in der UI angezeigt
+- Übersetzung: „Schrittweite" und „Ziel"-Placeholder in Temperatureingaben werden jetzt korrekt übersetzt
+
+---

+
+---
+
+## [0.9.1-beta8] – 2026-04-25
+
+### Neu
+- Restdruckzeit-Anzeige in der UI (≈ Xh Ym verbleibend) aus `remain_time`-Feld des Druckers
