 ### Fixes
 
 * [1372](https://github.com/zeta-chain/node/pull/1372) - Include Event Index as part for inbound tx digest
+* [1367](https://github.com/zeta-chain/node/pull/1367) - fix minRelayTxFee issue and check misuse of bitcoin mainnet/testnet addresses
 * [1358](https://github.com/zeta-chain/node/pull/1358) - add a new thread to zetaclient which checks zeta supply in all connected chains in every block
