I am very excited for the new features for 8.4.0. However, there are a number of things that are not working. For me, it is the inability to export to an mp4 with 5000 kbps bitrate setting. And, the number of crashes being experienced has increased.
Basically, my group had to go back to 8.3.0 (build 1471).
Thus, we look forward to the "next" release. Do you have any projections on this next release date?
