 # Changelog
 
+## [0.9.16] – 2026-05-22
+
+### Neu
+- **Kamera bei Druckstart automatisch einschalten:** neue Einstellung „Kamera bei
+  Druckstart einschalten" — die Bridge startet den Kamera-Stream automatisch, wenn
+  ein Druck beginnt (für OrcaSlicer und die Bridge-UI).
+
+### Fixes
+- **Einfarbiger Druck durch leeren AMS-Slot blockiert:** OrcaSlicer schreibt alle
+  konfigurierten Filamente in den GCode-Header, auch wenn das Modell nur eines
+  nutzt — die Bridge meldete dem Drucker dadurch alle Farben als nötig, und ein
+  leerer ungenutzter Slot brach den Druck ab. Die Bridge mappt jetzt nur die im
+  GCode tatsächlich genutzten Filamente.
+- **Filament-Sync jetzt positionstreu:** Bei einem leeren Slot in der Mitte
+  (z.B. Slot 1 gelb, 2 leer, 3 rot, 4 weiß) zeigte OrcaSlicer die Farben auf den
+  falschen Slots. Behoben — leere Slots behalten ihre Position, und das
+  Sync-Farbformat folgt der Happy-Hare-Konvention (RRGGBB ohne `#`).
+- **Slicer-Zeit + Thumbnail fehlten nach Browser-Reload** (oder bei Druckstart
+  direkt aus OrcaSlicer): beide werden jetzt aus dem GCode-Store anhand des
+  Dateinamens wiederhergestellt statt aus flüchtigem State.
+- **Deutsche Übersetzungslücken** im ACE-Trockner-Dialog behoben.
+
+### Logging
+- Wiederholte Log-Zeilen werden als Zähler („×N") zusammengefasst statt zu spammen;
+  Status-Poll-Verkehr wird nicht mehr auf INFO geloggt.
+- Neuer Level-Filter (Alle / Fehler / Warnungen), Toast bei neuen Fehlern, volle
+  Tracebacks im Browser-Log und ein Download-Dateiname mit Zeitstempel.
+
+## [0.9.15] – 2026-05-21
+
+### Fixes (Issue #29)
+- **UI im OrcaSlicer-Device-Tab kaputt:** OrcaSlicers eingebetteter Webview lädt
+  nur das nackte HTML und ignoriert externe `<script>`/`<link>`-Tags — nach der
+  v0.9.14-Theme-Auslagerung funktionierte dort kein Button mehr. Die Bridge
+  bettet CSS + JS jetzt inline in die Seite ein — funktioniert in Browser UND
+  OrcaSlicer-Webview.
+- **Dropdowns unlesbar (weiß auf weiß) im OrcaSlicer-Webview:** `color-scheme` +
+  explizite `select`/`option`-Farben ergänzt, damit die nativen Dropdowns in
+  Hell- und Dunkel-Theme korrekt dargestellt werden.
+- **„Select slots"-Button tat direkt nach Upload nichts:** eine fehlende
+  Variablen-Deklaration (`storeFiles`) warf einen `ReferenceError`, wenn vor dem
+  Laden des Browser-Tabs geklickt wurde. Behoben.
+- **Upload-Banner kam nach abgeschlossenem Druck zurück:** der „file ready"-Status
+  wurde nur bei Stop/Abbruch geleert, nicht bei `finished`. Jetzt auch nach
+  erfolgreichem Druckende geleert.

 # Changelog
 
+## [0.9.16] – 2026-05-22
+
+### New
+- **Auto-start camera on print:** new setting "Turn camera on at print start" —
+  when enabled, the bridge starts the camera stream automatically when a print
+  begins (works for both OrcaSlicer and the Bridge UI).
+
+### Fixes
+- **Single-color print blocked by an empty AMS slot:** OrcaSlicer writes all
+  configured filaments into the GCode header even when the model uses only one,
+  so the bridge told the printer it needed every color — and an empty unused slot
+  aborted the print. The bridge now maps only the filaments actually used by the
+  GCode.
+- **Filament sync now position-accurate:** with an empty slot in the middle
+  (e.g. slot 1 yellow, 2 empty, 3 red, 4 white) OrcaSlicer showed the colors
+  shifted onto the wrong slots. Fixed — empty slots keep their position, and the
+  sync color format follows the Happy Hare convention (RRGGBB without `#`).
+- **Slicer time + thumbnail missing after a browser reload** (or when a print was
+  started directly from OrcaSlicer): both are now restored from the GCode store
+  by filename instead of relying on volatile state.
+- **German translation gaps** in the ACE dryer dialog fixed.
+
+### Logging
+- Repeated log lines are collapsed into a counter ("×N") instead of spamming the
+  console; status-poll traffic is no longer logged at INFO.
+- New log level filter (All / Errors / Warnings), a toast on new errors, full
+  tracebacks forwarded to the browser log, and a timestamped download filename.
+
+## [0.9.15] – 2026-05-21
+
+### Fixes (Issue #29)
+- **UI in the OrcaSlicer device tab was broken:** OrcaSlicer's embedded webview
+  only loads the bare HTML and ignores external `<script>`/`<link>` tags, so after
+  the v0.9.14 theme split none of the buttons worked in the device tab. The
+  bridge now inlines CSS + JS into the page — works in both the browser and the
+  OrcaSlicer webview.
+- **Dropdowns unreadable (white-on-white) in the OrcaSlicer webview:** added
+  `color-scheme` + explicit `select`/`option` colors so the native dropdowns
+  render correctly in dark and light theme.
+- **"Select slots" button did nothing right after an upload:** a missing variable
+  declaration (`storeFiles`) threw a `ReferenceError` when clicked before the
+  Browser tab had loaded. Fixed.
+- **Upload banner came back after a finished print:** the "file ready" state was
+  only cleared on stop/cancel, not on `finished`. Now cleared on completion too.
