when you use a script like 

Metacello new
  smalltalkhubUser: 'Pharo'
  project: 'MetaRepoForPharo40';
  configuration: 'QualityAssistant';
  load

and you already have the configuration package loaded, the script is not updating the configuration itself. As the result you cannot update to a newer version. Is there a special expression that has to be used to update the configuration package? If not, maybe it does make sense to update the configuration before loading it?

Cheers!
