 ## Recently Fixed
 
+### Bug Fixes (2026-06-27)
+- Fixed `calculate_withdrawal` in `liquidity-pool-contract` to return 0 when `total_shares == 0` (empty pool)
+- Added `get_loan_counter` public function to `creditline-contract` for frontend loan enumeration
+- Fixed frontend `soroban.ts` to call `get_loan_counter` instead of non-existent `all_loans_count`
+- Added `vouching-contract` to `deploy-testnet.sh` (build, deploy, initialize, env output, JSON manifest)
+- Suppressed unused-function warnings (`#[allow(dead_code)]`) on `div_u64`, `add_u32`, `sub_u32`
+
 ### Issue #7 — Follow-up: Missing `approve_vendor` in `RealIntegrationCtx::register_vendor`
 - Discovered second `register_vendor` helper in `RealIntegrationCtx` (integration test struct, ~line 2390) that only called `register_vendor` without `approve_vendor`
 - All integration tests using `RealIntegrationCtx` created loans with `Pending` vendors → `validate_vendor` → `is_active` returned `false` → `VendorNotActive` (#3)
