Hello.
The link you postetd it to some specific version that is not the latest one (ling hash code in the URL indicates specific version).
After getting the latest one just reimport the bundle (simply import once again a new version). This link leads to latest ge4d / hubitat-code / Bundles — Bitbucket
Bundle holds everithyng to install that is needed (full set of libraries, drivers, apps and a metadata file with installation info for hub). Update and fresh install procedures are no different from one another. When new version of bundle is imported all the related drivers/libs are replaced accordingly.
Will it break your setup? Depends on your setup. Most probably no.
The breaking point is a device reconfiguration if child devices will be re-created. The driver does not deletes everything and creates from scratch. Instead it builds the list of required child devices and compares with what you have. The changes then are applied only to differences. If there is a child device missing it will be spawned. If there is some extra child device it will be removed. So reconfiguring is safe (changing names and labels does not affects this - driver uses internal 'network ID' for all child devices to uniquely identify them)
The child device addressing were not changed for a very long time. So your old device should remain fully functional after the bundle/driver update.
Not sure if these points represent what you are asking about..
