Joel, Altium have other priorities for now . Seems that Altium Designer 18 it's not quite finished yet and their efforts are focused there. They don't care so much about CS as they care for their flagship software.
Since most likely the same team that works on AD is working on CS, it's no wonder that CircuitStudio is on standby.
My guess is that they will try to release an update for CS just to fulfill an obligation but I will not expect something big.
Just have a a few obvious bugs solved, might add some menu buttons for functions that are already there (callable through the search field). An 1.4.2 update.
For me, it's not the first time that "I'm betting the wrong horse".
I mean, this is not a "bad horse" but a "slow horse"
For now, it's doing it's job and just that.
