5.0.1, the first bugfix release in the 5.0.x series, seems to be around the next corner, see https://lists.launchpad.net/kicad-developers/msg37572.html. Now it would be a good time to test the nightlies, see https://forum.kicad.info/t/nightly-builds-available-for-5-0-x/1252.
At the moment it’s uncertain whether there will be 5.0.2 because 5.1 is relatively near. Maybe it will be decided after 5.0.1. I’ll try to keep you informed.
