For those who use the Subset Schema Generation Tool (SSGT): If you are interested in testing, searching, or trying subsets, our staging server is up and running with 4.1 Beta1. Please note, the staging server may seem a bit slower than the production server as it does not have the same computing power. Access this version of SSGT.
