+## [1.4.2] – 2026-05-20 — Hotfix: Admin leer & Legacy-Symbole
+
+### Behoben
+- **Admin Symbol-Manager**: Liest jetzt korrekt `categories` statt `groups` aus der API-Response von `/api/tenant/symbols?grouped=true`.
+- **Datenmigration (Step 18)**: Neue Migration in `prisma/migrate.js` migriert bestehende `tenantSymbols` automatisch: setzt fehlende `name`, `svgPath`, `categoryId` (Default-Kategorie „Meine Symbole“) und `migratedFromIconId`. Behebt „Leichen“ mit broken images.

 ## [1.4.1] – 2026-05-20 — Hotfix: Production 500 & Null-Crash
