 ## [Unreleased]

+## [0.4.0] - 2026-10-25
+
+Ein neues Gesicht: Bricktrack sieht jetzt aus wie das, was es verwaltet.
+Dazu alle bekannten Sicherheitslücken in den Abhängigkeiten geschlossen.
+
+### Sicherheit
+
+- Next.js 15.5.28: schließt unter anderem eine Denial-of-Service-Lücke über
+  Server Actions und Cache-Poisoning bei selbst gehosteten Instanzen. Die
+  kritische Lücke in der Bildoptimierung war hier nicht ausnutzbar
+  (`images.unoptimized`), ist aber ebenfalls behoben.
+- nodemailer 10.2: mehrere Fehler im Adressparser (Erinnerungs-Mails).
+- better-auth 1.7.12, sharp 0.35.5 (librsvg), zod 4.6.7 (Speicherverbrauch
+  bei übergroßen Eingaben), drizzle-orm 0.45.4.
+- Entwicklungswerkzeuge: vitest, vite, postcss, Playwright und die
+  shadcn-CLI aktualisiert, transitive Pakete per `pnpm.overrides` angehoben.
+  Übrig bleibt ein mittlerer Fund in einem alten esbuild, das drizzle-kit
+  intern mitbringt - nur beim Entwickeln, nicht im Image.
+
+### Hinzugefügt
+
+- **Designauswahl** unter Konto → Design: Klemmbaustein (neuer Standard),
+  Warm, Nachtblau (dunkel), Bonbon, Bauklotz und Schlicht (der bisherige
+  Look). Die Wahl gilt pro Gerät und wirkt sofort.
+- **Platzhalter für Sets ohne Bild**: Farbe des Herstellers, gezeichneter
+  Stein und Setnummer statt eines grauen „Bild fehlt".
+- **Startseite als Überblick**: Steinreihe für den Fortschritt (bei mehreren
+  Sammlern in deren Farben), Teile, Wert, nächster Wunschlisten-Termin mit
+  Countdown und Abkürzungen.
+- Neues Logo als Baustein, Schriften lokal gebündelt (kein CDN).
+
+### Geändert
+
+- Karten, Buttons und Badges tragen im Standard-Design Konturen, eine feste
+  Unterkante und Noppen. In der Sammlung und auf der öffentlichen
+  Wunschliste zeigen die Noppen den Sammler bzw. ob ein Wunsch reserviert ist.
+- Die öffentliche Wunschliste hat einen farbigen Kopf mit Anlass und Datum.
+- Screenshots der Anleitung zeigen die feste Navigation nicht mehr mitten
+  im Bild.
