This update adds better error handling for X-Mas trees loading and provides some improvements for better compability with custom worlds plugins like Multiverse, PlotSquared, etc
Also this one uses new recipe constructor because old one is marked as deprecated and would give you a warning in server console.
However if your server has no custom worlds.and you aren't experiencing any troubles with your version then you can skip this update without a back thought.
Happy Holidays everyone!
