Methods

Method	Returns
`currentPlan()`	The scheduled upgrade plan: its name, height, and info. If there is no scheduled upgrade, all fields are empty or zero.
`appliedPlan(name)`	The block height where the chain applied the named upgrade, or `0` if the chain did not apply it.
`upgradedConsensusState(lastHeight)`	The stored upgraded consensus state for `lastHeight`, or empty bytes if there is none.
`moduleVersions(moduleName)`	The consensus version of the named module. Pass an empty string to get all modules. The call reverts if the module is unknown.
