I agree that the website wording is slightly confusing, however the idea is to indicate that these licenses are
backwards compatible for all the 3.x versions, not forwards compatible.
Since we only have licenses for the most recent version of TestStand
available at a given time, this backwards compatibility allows somebody
with a 3.0 sequence they wish to deploy to purchase a license that will
work, even though only 3.1 deployment licenses are available. However a
3.0 deployment license needs to be upgraded before a 3.1 sequence can
be deployed under that license.
I apologize for the confusion, I hope this answers your questions.
