func NewUpgrade ¶

func NewUpgrade() upgrades.Upgrade

NewUpgrade constructs the upgrade definition.

x/ucallback is a new module, so its store has to be added here — RunMigrations alone will register the module's consensus version but cannot create a store that the multistore was never told about, and the node fails to load at the upgrade height without it.
