A huge list of bug fixes and improvements across the board. The GUI has been improved further, and even a touch screen gesture mode was added.

The difference is night and day compared to the first buggy and ugly release on March 2016! It now runs stable, and many new features have been added over the scope of (almost) three years. The GUI has been much improved since then.
OpenToonz was used in the production of Mary and the Witch’s Flower, a feature-length Japanese animation film.
