Periodically we receive announcements of new maintenance builds of Oxygen XML Editor. It's easy to locate documentation on installing new versions, but I was unable to find any instructions on installing maintenance builds. 

In the past I've renamed the downloaded folder, e.g, "17-1", which completely duplicates all the files in Applications (I'm using OS X), then later on deleted the older folders when it seemed safe to do so. 

I would like to know the best-practice, most efficient way to routinely install these frequently released maintenance builds.
