+## Governance Events
+The governance process is handled by the cosmos-sdk `gov` module. We do not emit any events of type "message" anymore in v0.18+.
+Context-specific events are emitted as described above. `Execution` and `Migration` return some contract result though that are
+emitted as:

+sdk.NewEvent(
