#### Chores

* **Latency Optimization:** Shipped a technical rewrite reducing /price endpoint response times—p95 latency dropped from \~1s to \~500ms, and p50 latency decreased from \~550ms to \~340ms—with no impact on pricing performance.

#### Bug Fixes

* **MNT and POL Compliance**: Improved support for MNT and POL tokens, which do not fully adhere to the ERC20 standard.
* **Slippage Handling**: Slippage now correctly caps at the maximum specified basis points (bps).
* **Meta-transaction Settler**: Fixed an RFQ handling issue in the meta-transaction flow.

#### Documentation

* New [guide](/evm/0x-swap-api/additional-topics/handling-native-tokens) on best practices for swapping native tokens (e.g., ETH).
