 ### Breaking changes
 
 * SolidlyV3 UniV3 fork removed from Mainnet and Sonic
-* Abandon Katana chain (which only had stripped-down Settler anyways)
 * `BRIDGE_TO_CCIP` modified to remove the `token` argument that is already included in `ccipSendData`
 * `BRIDGE_TO_LAYER_ZERO_OFT` modified to remove the `nativeFee` argument that is already included in `sendData`
 * `BRIDGE_ERC20_TO_MAYAN` and `BRIDGE_NATIVE_TO_MAYAN` modified to remove `forwarder` argument. It is now hardcoded.
