+## PlantType system is now replaced (introduced in NeoForge 21.0.39-beta)
+
+The original PlantType system was buggy and quite confusing to deal with. Instead, we deleted that system and added `SpecialPlantable` item interface, patched in a `canSustainPlant` block method, and added a `neoforge:villager_farmlands` block tag. 
+
+The `SpecialPlantable` interface allows mods to more easily tell if a modded item can spawn a plant and exposes methods for easy checking if a spot is valid for the item and to spawn the plant itself. 
+
+The patched-in `canSustainPlant` method allows blocks to forcibly sustain many plants and now works with all vanilla plants. Modded plants would need to call this method if the plant block override canSurvive without calling super. 
+
+And the `SpecialPlantable` block tag now lets Farmer Villagers detect and plant on modded blocks more easier. This can also be used by mods to know if a modded block is farmland-like.

 ## Experimental Gradle Plugin
 We're currently developing a new experimental Gradle Plugin, focused on simpler buildscripts and improved caching. You can find information on its usage [here](https://github.com/NeoForged/ModDevGradle), and support is provided in the [thread](https://discord.com/channels/313125603924639766/1239579489617580072) on our [Discord server](https://discord.neoforged.net).
