Will the Matrix Voice microphone array be supported?

I want to give it a try. After burning current image from https://mycroft.ai/to/picroft-image and burning to sd card the initial setup is starting.
The choice for matrix voice is missing. As seen in the PR there should option number 4 for matrix voice

echo " 4) Matrix Voice HAT.")

But this option is missing.
The PR seems to be in the “stretch” branch, but not in the “master” branch. How can i be sure to use the right version?

Do i have to install the matrix voice kernel modules manually after the wizard or will this be done by mycroft setup (Picroft / Mycroft.AI with MATRIX Voice).
