Unfortunately, version 19.12.16 introduced a major new bug when moving clips on the Timeline with Ripple on. This version not only fixes that and a few other new bugs, but also it includes the highly requested feature that did not make it into the release: moving multiple clips on the Timeline!
In addition, two more video scopes were contributed: RGB Parade and RGB Waveform. Lastly, a change to allow reducing track height to be very short.
