 ## [Unreleased]
 
+## [3.4.0] – 2026-10-18
+
+### Neu
+
+- **Dateien:** Umbenennen in der Bibliothek (Stift-Icon; Endung bleibt erhalten).
+
+### Behoben
+
+- **Bedarf „443 g fehlen“ trotz voller Spulen:** Slice-Farbe `#26A69A` matchte nicht Lagerfarbe „Grau“ → Rest 0. Bei Hex-Farbe zählt jetzt der Rest gleicher Sorte; archivierte Spulen nicht.
+- **Falsches „Material nachlegen“ bei manueller Pause:** Anycubic meldet `active_filament.empty=true` auch ohne Runout (`tool`/`gate` = −1). Heuristik nur noch bei Meldung/`reason_for_pause`/10107, aktivem Tool + differenziertem `gate_status`, oder G-code-Store.
+- **gklib 10111 nach Einfarbig-Upload:** Orca-Zeile `; filament_colour_type` wird beim Senden entfernt (nur Einfarbig; Multicolor unangetastet).
+- **Protokoll „druckt“ nach Offline:** Live-Läufe werden bei anhaltendem Offline als `interrupted` geschlossen (z. B. gklib-Shutdown).
+- **Sorte „Sunlu PLA“ vs. Eryone PLA:** Basis-Profil ohne Meta/Matte/Silk matcht nach Material-Typ (Marke egal); Varianten bleiben streng.
