Outdated documentation - What does "Is this build for distribution to the public" checkbox do?

Recently updated from 4.11 to 4.13 and noticed some differences in the project launcher.
What does “Is this build for distribution to the public” checkbox do?
Whats the difference it makes?

There is also a new “Archive” but I assume it makes a duplicate of the build elsewhere.

Thanks for any information!
