     * Added Magenta through White Fuel/Matter (would have added fading matter, but it's over 1 trillion EMC)
     * Added `_get_emc`, `_set_emc`, and `_add_emc` to player metatables. This means you can use `player:_get_emc()` instead of `exchangeclone.get_player_emc(player)`. **WARNING: Do not use these functions in `on_joinplayer` functions.**
     * Added the same functions for itemstack metatables, as well as `_<get/set/add>_star_emc` and `_get_star_max`. `_set_emc` and `_add_emc` work by changing the metadata EMC value.
+    * Added Evertide/Volcanite Amulets
+        * Projectiles do not work in Mineclonia.
+        * The "Buckets use select box" (`mcl_buckets_use_select_box`) setting must be enabled to use projectiles in MineClone2.
+        * Pedestal abilities use the "Weather" mod (the one by theFox) in Minetest Game
 * Changes:
     * The Constructor and Deconstructor are now deprecated, replaced with the EMC Link.
     * Upgrades and Stars can no longer be used as fuel.
