Hi Jan,
just a heads up: the last months we (at ExactCODE) were way too busy with
projects not related to T2. So unfortunately from our side we put less time in
using and polishing T2 as we did before with certain embedded projects.
Of course that may change every other quarter as we have projects coming in and
such, …
Patches welcome! Guess I should update T2 on my G5 for the cross build test of
it, … ;-)
