This release is safe to use on earlier Spigot versions, but has almost no changes relevant to pre-1.16.1 versions.

• Support should properly render all new 1.16.1. blocks
• Rendering of wall blocks should handle the new vertical connection added in 1.16.1
• Should handle pristine 1.16.1 worlds, as well as those upgraded from 1.15.2
• Do be sure to use the latest Spigot 1.16.1 - everyone has been moving very fast on this release!

Please be sure to report any issues found with this release (3.1-beta-1-367) or newer after confirming the issue with the latest Spigot (or PaperMC, when that becomes available).
