+### FEATURES
+
+- Add an optional per-chain setting `compat_mode`, which can be
+used to specify which CometBFT compatibility mode is used for interacting with the node over RPC.
+([\#3623](https://github.com/informalsystems/hermes/issues/3623))
+- Add a configuration which allows to override the `clear_interval` for specific
+chains ([\#3691](https://github.com/informalsystems/hermes/issues/3691))
+
+### IMPROVEMENTS
+
+- Hermes now saves on fees by not including a client update if the
+consensus state at desired height is already present on chain.
