it seems I was wrong (or misunderstood the context) – tomorrow, it’s not the start of common test (CT) but apparently 9.5 supertest (ST). I think the confusion might have come from the fact I mixed the terms CT (“common test”) and “CT” (in Russian, CT reads as ST, “supertest”). As far as I know, this is the first time it happened to me, mea maxima culpa, I apologize.
The way I GUESS it is now, based on previous experience (9.5 test ETA):
27.11. – 4.12.: Supertest 9.5
4.12. – 11.12.: Public test round 1
11.12.- ??.12.: Public test round 2
22.12. or 23.12.: release date
They might squeeze a third round in there somewhere.
