It's really NOT tricky at all. You have a test site. You have an official public product website. Sometimes you put up a test version on the test site. Sometimes you feel a beta is mature enough to release at the official product website.
Verbiage:
"The next version of Goldfish Aquarium we are working on will skip the Prolific test site and become the official Release version at
www.LifeGlobe.com. For the general public, this will be the first available version with Monstro. This next beta
is/is not a new build which
does/does not address bugs which have been reported in the May 19th
1618 build."
