v0.5.0

This release allows the IP address used by the integration to access a Hubitat hub to be changed (#31). (In previous versions, updating the IP required the integration to be removed and re-added.)

Note that installing this version will migrate the unique IDs of all entities to a new format that uses the Hubitat MAC address rather than its IP address. This means that downgrading, while still possible, is more involved than just installing a previous version, so you may want to make a snapshot before updating.
