This is still an Alpha version, which means there’s still a lot of development remaining, but it is already considered "usable". i.e. you can already use it without breaking the sun, even if some (a lot of) features are still missing and there's still some (a lot of) bugs. It is not ready for use in production.
Duik 17 is in development.
It’s been funded thanks to a crowdfunding campaign a year ago. At that time we proposed to develop a new minor version of Duik 16 (Bassel), the third one, but finally we’re stepping to Duik 17, and this will be a much more complete update than what was initially planned!
