 ## [Unreleased]
 
+## [2.5.1] – 2026-10-17
+
 ### Neu
 
+- Cockpit-Steuerung: ACE-Trockner starten/stoppen (Temp, Dauer), nur wenn ein ACE hängt.
+- Cockpit-Steuerung: bestückte ACE-Plätze mit Sorte und Farbe aus Grotti an den Drucker schreiben.
 - Wand-Kacheln zeigen das Druck-Vorschaubild (Moonraker-Thumbnail) in der Job-Zeile.
+- **Druckbericht** `/protokoll/<id>`: Soll/Ist-Gramm, Spulenanteile, Temperaturverlauf, Ereignisse, Charge.
+- **Statistik** `/statistik`: Auslastung, Erfolg, Verbrauch, Ausschuss, Schätztreue; CSV-Export.
+- Spulenakte unter Material: verdruckte Gramm, Ausschuss, Leer-in aus dem Wochenverbrauch.
+- Etiketten pro Druck oder Objekt (`D-YYYYMMDD-nnnn`), QR auf den Bericht; Scan von `D-…` öffnet den Bericht.
+- Spulenabzug nach Ist (`filament_used`); Abbruch nur anteilig; Mehrfarb-Anteile als Schätzwert; Rest darf ins Minus.
+- Rollenwechsel während Druck/Pause (Einlegen) teilt den Verbrauch in Abschnitte.
+
+### Geändert
+
+- Statistik: Zeitraum per Knopf (Tag, Woche, Monat, Gestern, Letzte Woche, Letzter Monat, Alles); Bis-Datum zählt inklusiv; CSV übernimmt denselben Filter.
+- Druck-Charge `D-…` wieder während des Laufs (Protokoll, Wand-Etikett, Bericht); Adoption übernimmt die Nummer auf den History-Job. Ausschuss: gedruckte Bögen verwerfen, Charge bleibt.
+- Dateien → ACE-Zuordnung: Platz-Dropdown zeigt bei bekannter Spule Material, Farbe, Name und Restgramm.
 
 ### Behoben
 
+- Spulenakte blieb leer: Abzug schrieb oft kein `run_spools` (hängende History-Läufe, Abzug vor Akte-Tabelle); Nachzug ohne erneuten Rest-Abzug, Abzug schreibt `run_spools` vor `deducted`.
+- Protokoll: keine Doppel-„druckt“-Zeilen mehr (Live + History); Watcher hängt am History-Job, sobald Moonraker ihn kennt; Liste blendet überzählige Live-Zeilen aus.
+- Platte geräumt: `needs_clear` nach Watcher-Ende und History-Sync (nur wenn kein Live-Druck); neuer Druckstart bricht alte Live-Läufe ab.
+- Druck-Etikett: Material schon während des Laufs (Send/ACE/Spule); QR bleibt im 70‑mm-Bogen.
+- Druckstart: Dateien mit altem `stored_path` (z. B. nach Umzug von `3DP/…/Uebersicht` nach Grotti) werden unter `data/eingang/<name>` wiedergefunden statt „liegt nicht mehr auf der Platte“.
+- Wand/Sidebar: Dateiname springt nicht mehr alle paar Sekunden, wenn Moonraker kurz keinen Namen liefert; 3D-Pfad-Caption flackert nicht mehr mit „wird gelesen …“.
+- Dateien: Hinweis zu fehlendem ACE-Trailer nur noch bei Mehrfarb (nicht als Warnung bei Monoteilen).
 - 3D-Pfad wirkte gesprenkelt: Ausdünnen behält ganze Schichten dicht (statt Stichproben entlang der Bahn); keine Parallel-Offsets.
 - Toolpath-API mit `Cache-Control: no-store`, damit der Browser keinen alten Pfad behält.
 - Senden: Dateinamen mit Nicht-ASCII (z. B. CJK) werden für Moonraker/Rinkhals auf ASCII normalisiert — sonst Fehler 10115 „gcode … not found“.
