Where is the setting that ?v9=true is supposed to set?

Where is the setting that ?v9=true is supposed to set?

Add it to the end of your url. So http://chilipeppr.com/tinyg + that bit after the tinyg http://chilipeppr.com/tinyg

No, I mean, when we use that query parameter, which setting is being changed in CP configuration? Is there a checkbox or something in the panels that is changing ?

Look at the source code to the TinyG widget and just search for that string. You’ll see what it does.

Ok so it is actually the other way round. There is a setting in CP/tinyg which just links to the v9=true mode.
We are now solidly using tinyg2 on the DUE. Maybe it is time now to make our own build with the latest edge.
