+- Split out consumer genesis state to reduce shared data between provider and
+  consumer. ([\#1324](https://github.com/cosmos/interchain-security/pull/1324))
+  - Note: This breaks json format used by augmenting Genesis files of consumer 
+  chains with consumer genesis content exported from provider chain. Consumer 
+  Genesis content exported from a provider chain using major version 1, 2 or 3 
+  of the provider module needs to be transformed with the transformation command 
+  introduced by this PR:
+    ```
+    Transform the consumer genesis file from a provider version v1, v2 or v3 to a version supported by this consumer. Result is printed to STDOUT.
+
+    Example:
+    $ <appd> transform /path/to/ccv_consumer_genesis.json
+
+    Usage:
+      interchain-security-cd genesis transform [genesis-file] [flags]
+    ```
