They do not plan to move until the 4.x is more mature and contains editing and drawing tools. I personally hope that they to not rush into the 4.x migration as there is still som many things missing from the 4.x API.
Thanks for the info Robert!
Robert, do you know how to check the Dojo version used by WAB 2.x? I am using WAB 2.5 right now but in general I want to make sure I am consulting the correct documentation for Dojo online. Thanks!
From the FAQ
WAB 2.5 is using JS API 3.21, so:
Dojo version 1.12.2 (since version 3.21)
True, but it would be also nice to have 2 WebAppBuilder 3.x and 4.x both following the update of the API to prepare the transition as well .
