When itīs so simple for you, than my questions:
Tilly
Perhaps we need to define what beta software is ...
Here's what Wikipedia has to say.
The difference between beta code and final code is that the manufacturer of the particular code states that one is beta and the other is not, and a particular piece of code can be deemed beta on a particular day, and then deemed a final release on a later day with absolutely no changes to the code itself.
In a nutshell, D-Link is going to be the one who decides if a particular piece of code is a beta test version and at some point when a particular piece of code passes it's quality assurance testing, it will be released as a final version.
To answer your question - if D-Link in the Netherlands chooses not to release one or more versions on the firmware for whatever reason and those versions have been released for use in other countries, it does not make those final versions, beta versions for the Netherlands - however, if D-Link in the Netherlands chooses to call one of them a beta and release it for testing, at that point it will become a beta version
for the Netherlands.
Is this likely to happen? I doubt it, but, that's just my guess.
Unless I am mistaken D-Link in the Netherlands would probably consider anything later than what has been released
on their support site as an unsupported versions, as I believe you already know.
