 ## Unreleased
 
+### State Machine Breaking
+
+* (app) [\#540](https://github.com/ChainSafe/ethermint/issues/540) Chain identifier's format has been changed to match the Cosmos `chainID` [standard](https://github.com/ChainAgnostic/CAIPs/blob/master/CAIPs/caip-5.md), which is required for IBC. The epoch number of the ID is used as the EVM `chainID`.
+
 ### API Breaking
