This release brings a new system for adding arbitrary content (sounds, music, images, blocks, items, etc.) to maps or servers. In terms of functionality, this is very close to what JSON mods can provide, except without any manual downloads necessary.

Servers can add content by dropping files into the appropriate assets/ subdirectory next to the server JAR. Note that patches have been moved into this directory as well.

Any maps/saves with assets in them must be exported through the in-game UI to work properly; for performance reasons, assets are not embedded in map/save files unless exported in this way.

This system will likely have serious bugs, so expect hotfix releases after this one.
