+## [1.43.22] - 2025-12-16
+
+### Fixed
+- **Widget de Projeção - Refresh Automático**
+  - FIX: Widget de projeção agora atualiza automaticamente quando há mudanças
+  - Sistema de eventos customizados para comunicação entre componentes
+  - Eventos implementados: `recurring-paid`, `transaction-created`, `transaction-updated`, `transaction-deleted`, `recurring-updated`
+  - Dashboard escuta eventos e força recarregamento via `refreshKey`
+  - CalendarWidget emite eventos após pagar/conciliar instâncias
+  - Widget de projeção desmonta e remonta para recarregar dados atualizados
+
 ## [1.43.21] - 2025-12-16
