Is PMMS available?

Dear authors, Your manuscript "Piecewise-stationary motion modeling and iterative smoothing to track heterogeneous particle motions in dense environments" (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5796444) states that "Our new motion model and estimator will part of the next release of the u-track platform at http://www.utsouthwestern.edu/labs/danuser/software/." Is PMMS now available? I cannot find it in this repo, though I may have missed something. Thanks in advance.
