Subscribers to Zorro S or to a Z system will receive new versions
How do we receive the new version? Does Zorro S have an auto-updater or something like that? Should we expect emails? Do we just download the installer and run it?
No, you can just install 1.44 over 1.42. You only must take care when you've modified .ini files or the like, since they then are overwritten by the new installation.
