I would like to know how to tell when KCT's version changes short of downloading the free trial and installing it. I can't find anything online where I can just look this up. Secondly, I want to know if/when KCT is going to add Nexus support as an option when configuring a new device
We are looking at adding automatic notifications in-product. For now, you'd want to subscribe to the Announcements area of the forum and we'll be sure to advertise new Kiwi releases there.
Nexus support is also something we've been exploring. I believe we have some example scripts that you can try. You'll need to open a support ticket and include a link to this post. Let them know the PM wants you to help test Nexus support.
