This release is a beta. Do not use on your production server unless you have backup of your data and fully understand the risks.
This version adds support for 1.16.x, and provides a temporary-fix for a duplication exploit. It also changes the way items in shulkerboxes are displayed.
I have not extensively tested this release. Please note, 1.16.1 is still pretty much a work-in-progress and bugs are constantly being fixed.
