# BMC Hub v2.2.3 - Migration Hotfix

**Release Date:** 22. februar 2026

## 🛠️ Hotfix

### Migration 138 compatibility fix
- Fixed `migrations/138_customers_economic_unique_constraint.sql` for environments where `customers.economic_customer_number` is numeric (`integer`).
- Removed unconditional `btrim(...)` usage on non-text columns.
- Added type-aware normalization logic that only applies trimming for text-like column types.

## ✅ Impact

- Migration `138_customers_economic_unique_constraint.sql` now runs on both numeric and text column variants without `function btrim(integer) does not exist` errors.
- Unique index safety behavior and duplicate detection are unchanged.
