I have been really busy with other stuff - RPS is waaay down on my list of priorities right now as I am not working with BIM at all anymore.
So, no, I will probably not update RPS 2015 and 2016 to deploy to RPS 2017. I will probably end up dropping support for older Revit versions (2018 is coming soon I guess?) instead.
What are your thoughts on how long old Revit versions should be supported?
If we can move to a newer IronPython with RPS 2017, would it really matter that the 2015 and 2016 branches be neglected?
This would be a really good moment to explain how having the feature "deploy to R2017" would benefit you, Callum. I'm afraid I am too far removed from the use case to make a good decision on that. What are your inputs?
