Full 1.14 support (and the deprecation of previous versions)
New | Quests now natively uses the 1.14 api, so it will be compatible with 1.14 blocks.
This also means that it cannot be used on versions before 1.14.
Item IDs no longer work as a result of this.
You may see a lot of stone blocks as the names for a lot of items have changed to their vanilla variant. This will require manual fixing. See this listfor the names (ignore LEGACY blocks).
