+### Core Module Enhancements
+
+**Mint Module**
+- Added `Mint.getByHex()` and `Mint.getAssetsByPolicyHex()` utilities for hex-based lookups
+- Fixed `Mint.insert`, `removePolicy`, `removeAsset`, and `get` to use content-based equality (`Equal.equals`) instead of reference equality for PolicyId/AssetName lookups
+
+**Fee Calculation**
+- Fixed `calculateFeeIteratively` to include mint field in fee calculation via TxContext access
+- Removed unnecessary 5000n fee buffer that caused fee overpayment
+
+**Transaction Builder**
+- Added `.mint()` method to TransactionBuilder for native token minting/burning
+- `.attachScript()` now accepts `{ script: CoreScript }` parameter format
+- Improved type safety by using Core types directly instead of SDK wrappers
+
+### Devnet Package
+
+**Test Infrastructure**
+- Added `TxBuilder.Mint.test.ts` with devnet submit tests for minting and burning
+- Updated `TxBuilder.Scripts.test.ts` to use Core types (`PlutusV2.PlutusV2`) instead of SDK format
+- Refactored `createCoreTestUtxo` helper to accept Core `Script` types directly
+- Removed unused `createTestUtxo` (SDK format) helper
+- Added `Genesis.calculateUtxosFromConfig()` for retrieving initial UTxOs from genesis config
+- Replaced all `Buffer.from().toString("hex")` with `Text.toHex()` in tests
+
+### Breaking Changes
+- `attachScript()` now requires `{ script: ... }` object format instead of passing script directly
+- Test helpers now use Core types exclusively
