@@ -11,6 +11,10 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 - Staking runtime api to check if reward is pending for an era ([polkadot-fellows/runtimes#318](https://github.com/polkadot-fellows/runtimes/pull/318))
 - Allow any parachain to have bidirectional channel with any system parachains ([polkadot-fellows/runtimes#329](https://github.com/polkadot-fellows/runtimes/pull/329))
 
+### Changed
+
+- Transaction payments work via new `fungible` trait implementation ([polkadot-fellows/runtimes#332](https://github.com/polkadot-fellows/runtimes/pull/332))
+
 ### Fixed
 
 - Handle extra erroneous consumer reference when a nomination pool is destroying ([polkadot-fellows/runtimes#318](https://github.com/polkadot-fellows/runtimes/pull/318))
