Hi ercan2423, sorry I don't know a release date quite yet. I'm still in the process right now of working on the viewport display part. Once that is functioning well I will release the first v4 beta release and that will start the beta test process. Then there will be a beta test period for a while after that, anything like 6 to 12 months, before the final release will be ready.

So not too much longer for the first v4 beta release but the final v4 release is still a ways out.
