Já tem uma data para a 1.4 ou a 1.3
We don’t. the target for now is end of October for 1.30, but we don’t still know when that will exactly be.
1.40 we have no idea, we still have to do 1.35 first which will probably land on Christmas or near, so 1.40 is most likely next year.
that technically implies that, at latest, the 1.30 update would be released by the 31st of this month. Though I could be wrong as it depends on how things go.
That would be correct indeed. If everything goes well, at maximum would be the 31st of October.
