Hi everyone,
Experience Builder Developer Edition 1.20 has been released. However, the node cache package for offline installation is not yet available.
This is due to a delay in the JavaScript API package release, which has affected the final certification process. We are working to make the offline package available as soon as possible.
Thank you for your patience and understanding.
