There have been several threads about this on the forum. Are you talking about support for the new TimeZero version 4? Because v3 still works as it always has. We never took any features away. Time Zero has a new version of software v4 and Japan has been talking about adding similar support which it currently offers with v3. (for TZT2) If that is what you are talking about; the best guess is June 2020. I have learned a long time ago not to count your chickens until they hatch. Hopefully they will add V4 support but until it is supported; it isn't.
