WSJT-X v2.3.0-rc2

For the last 12 hours or so, I have been using the latest "release candidate" version of WSJT-X, which is 2.3.0-rc2.  Certainly on FT8 it appears stable and works well. The only thing I have found is an annoying pop-up box saying I do not have logbook of the world on my PC. I seem to recall this on an earlier version.
