Elingo's The Wild Update Concept Add-on
As announced in the recent Minecraft live event the Wild Update will be adding lots of stuff to Minecraft wilderness. One of them is the mangrove swamp biome. With this addon you can get a feeling of what the wild update will be like. Right now this addon only features blocks from the mangrove swamp, but I will try to add the rest of the 1.19 update to this addon.
