3 days ago, the stable version of Unity 2019.3 was officially released, to which UDCE is now ported (before that, development was carried out on Unity 2019.3 beta). In this regard, releasing UDCE on Unity beta does not make sense, so the transition to the stable version will be completed on the weekend, and a new alpha build of the program and a description of the new update 2.0 will be released.
