What will happen to the server api on labymod 4? While labymod 4 still registers the old labymod3:main plugin channel, disabling features shows a popup saying that they are disabled but they still work and disabling addons doesn't work at all. Getting a list of the player's addons returns an empty list. Will there be a new api?

currently you can still use the LabyMod 3 channel

there will be a new api later, but it is still unknown when

But like I said, using it doesnt work properly.
