We're all focused on R19 but there are still features in R18 that have not been fixed in what is rapidly approaching the entire life cycle of the product !!
Open Subdivision, for example, released with R18, broken in that it won't work with UV maps, and then that hasn't been addressed in the entire year that product has been out, which means that feature has never worked !!! It's stuff like that that makes me cautious about handing over my £600 every year. Even 3DS Max managed to integrate that correctly the first time they tried, and they are famous for releasing stuff that doesn't work !!! Normally MAXON are much better, but the Open Subdiv fail, the chronic catalogue of knife tool problems on release (thankfully mostly addressed 6 months later), and the still remaining knife tool 'cut visible only' problem are new exceptions it seems...
Indeed, I hope and perhaps rather need my faith in MAXON reassured by what's in R19, which hopefully will fix all that, and introduce new things that work straight away.
