We are planning to include all of the above mentioned Cordova versions in AppBuilder soon. Most probably, we will manage to introduce support for the latest Cordova iOS and Android bits by the end of the year or at the beginning of 2016. However, for the universal app development, we will require some more time and I cannot give an estimation at this stage.
Nevertheless, please share if there is certain functionality (except the Windows Universal Apps development) that is missing or a bug preventing your development in the current Cordova versions supported in our product, as we might be able to assist you further with it.
I hope this sounds okay and I am looking forward to your reply.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
