+- When enabled for misbehaviour (ie. when `mode.misbehaviour.enabled = true`),
+  Hermes will now monitors on-chain client updates and verify the submitted
+  headers comparing with headers it retrieves from its RPC node.
+  If it detects conflicting headers, it will now submit a `MisbehaviourMsg`
+  to the chain hosting the IBC client.
+  In addition, Hermes will also submit the evidence to the reference chain.

+- Emit event batches after a configurable delay.
+  This considerably reduces the latency when relaying
+  and therefore increases performance substantially on high traffic channels.
+  See the `batch_delay` setting in the per-chain configuration.
