1.14: Fireworks may not trigger correctly due to changes of how the explosion is triggered, Respawning may be slightly slower. Lighting is also a bit weird.
1.13: Block connections are now serverside, you can enable serverside support by turning serverside-blockconnections: true in the config (It will use extra CPU and RAM, be warned)
