I think. But it's up to you. Thanks, Kukjin

Merged now, since multiplatform is going in as well. What confused me for a while here was that this branch was based on a partial version of the DT branch, but it didn't match any of the branch heads we had merged in. It's not wrong to do so but it's useful to get a heads up in the pull request. -Olof
