This is a beta build, please let me know if any problem is introduced based on the update notes.
This update contains a lot of changes and new features

config changes:
- You can remove "replace-only-packets" from config.yml file since it's useless now.
- renamed blocks settings in config.yml:


new:
- ( Requires Spigot 1.16.2 or greater) added new custom block type. Block type: REAL_WIRE. WARNING: this feature is only for tests purposes and needs to be enabled in config.yml: disable-REAL_WIRE-behaviour: true.
- added new special property "surface_decorator" which allows you to make some blocks spawn on top of world surface, for example: flowers, rare minerals, light emitting artifacts...

- ( Requires Spigot 1.17.1 or greater) added custom resourcepack prompt message, you can change the "resourcepack-popup-message" property in the lang files
- added new attribute " symbol" to font_images. This allows you to specify a character to be retextured using an image https://emojipedia.org/ ‼️ This supports emojis (some emojis are not supported if they're make of multiple characters).
You can also specify a unicode value directly, example: \u1F47D
- ( Requires Paper) a hover popup will be shown on emojis sent by players. This can be disabled in config.yml "add-hover-suggestion_PAPER_ONLY"
- added a new attribute to trees_populators. "bottom_blocks", this will allow you to specify which valid base block a tree can spawn on. For example DIRT and GRASS_BLOCK.
- added sapling behaviour to spawn trees with saplings
- added a new property in config.yml to disable hosting completely "no-host" , so that you can upload the pack.zip file and handle the apply with another plugin.
