I posted a discussion to Github about our upcoming 1.0 roadmap. I'll repost it here for posterity.
0.9- A clean up release, primarily bumping versions to the latest across the board
0.10- First class Node support
0.11- A reboot of model loading and model configurations
Node support is a feature the community has been asking for. The relevant Github issue tracking that is here.
Along with Node support, revisiting the way models are loaded in UpscalerJS is next on our road to 1.0.
