+## 🩹 Recent Fixes & Compatibility Updates
+
+### 1. Odoo 19 Multi-Company Sharing Schema Compatibility
+- Swapped deprecated `company_id` filters with the new standard Many2many `company_ids` domain mapping when querying `account.account` instances. This prevents `ValueError: Invalid field account.account.company_id` backend crashes when creating loyalty discount products.
+
+### 2. Client Action Preprocessing Safety
+- Added explicit view layout parameters (`'views': [[False, 'form']]`) to the wizard action dictionaries. This prevents frontend JS crashes (`TypeError: Cannot read properties of undefined (reading 'map')`) when Odoo's web client pre-processes nested actions outside standard loaded actions.
+
+### 3. Real-Time State Synchronization
+- Chained a soft-reload client action (`'next': {'type': 'ir.actions.client', 'tag': 'reload'}`) directly within the approval notification return payload. This ensures that the voucher request's state immediately updates to **Approved** in the UI and lists the newly generated voucher cards without requiring a manual page refresh.
