The video type, the ending, the language setting and the check for your own script were built in this release and reached everyone a day later, together with the new look step. They are described on the page for 0.40.
Choose how your video opens and how it ends, pick the style, the narrator and the frame each in its own window, and have your own script checked before anything is made.
A finished video opens in four tabs, and one of them writes the post that goes with it, for the network you pick, from what your video says.
The only words on a frame are words from your video, a frame without a caption has no caption line, and a picture you describe is drawn the way you wrote it.
Everything that changed, newest first.
