   * 1.21 (enchantments, data pack paths, rendering): https://fabricmc.net/2024/05/31/121.html
 
 ### Technical/internal changes
-* Remove all random bits of legacy data support code; if we want to support world upgrades from pre-1.20.5 (which seems unlikely), we are going to need data fixer logic, which could also take care of legacy block entity properties, etc.
+* We are going to want to try to support world upgrades from 1.20, will need datafixers

 * Add MixinExtras dependency to allow for less hacky feature/fix implementations, e.g.:
   * zoom for Botania bows
   * apothecary filling via dripstone

 * Nether variants/behavior for pasture seed variants (either reuse existing seed types or make new ones to make nylium) and floral fertilizer (spawn mushrooms on nylium)
 * Switch ender air collection to use managlass vials and maybe also alfglass flasks instead of glass bottles
   * Ender Air Vials will be the same as current ender air bottles for throwing and crafting, except obviously return the vial instead of an empty bottle.
-  * The old Ender Air Bottles would need to remain as legacy item that is no longer survival-obtainable, but still converts back into empty vanilla glass bottles when used for crafting.
+  * The old Ender Air Bottles would need to remain as legacy item that is no longer survival-obtainable, but still converts back into empty vanilla glass bottles when used for crafting. (Would they? I think turning them to vials would be fine)
   * If Ender Air Flasks are a thing there are two options to deal with them. Either they are the same as the vials, or they have double the capacity. The latter could have multiple consequences:
     * They might create a slightly larger ender air cloud when thrown, or have a higher chance of causing ghasts to drop a tear. Larger clouds could be collected twice by empty vials.
     * They might be good for two crafting operations instead of one, leaving behind some kind of half-used ender air flask, which behaves similarly to ender air vials.
     * Pro: Larger ender air capacity would be consistent with the flask's larger brew capoacity.
-    * Con: Probably an automation headache, since full and half-used flasks do not stack with each other and count as compeltely different items for filtering.

 * Adjust order of colored items in UIs to match vanilla sorting (which is different from the order in `DyeColor`)
   * Item order in creative inventory for flowers, petals, etc.
   * Storage order in flower pouch (needs data fixer to migrate to item components — item components will be a breaking change, world update support may or may not happen)

 * Petal Pouch — variant of flower pouch that stores petals and glimmering mushrooms
   * automatically breaks down flowers into their petal form on pickup
   * maybe provide sxome kind of helper mechanism for selecting petals for the apothecary?
+* Try to finally get those mana API changes in
+  * Finer control of burst targeting and firing. For example allowing phantom bursts to pass through full spreaders/pools
+  * Mana splitter that shoots bursts (though nerf to not renew burst lifespan lol)
+* (This would be a big change with lots of consequences; Requires thorough discussion and testing) Consider tweaking the requirements for spreaders firing. For example, completely ignore fired bursts and fire at a fixed interval. Or maybe allow three bursts in flight at the same time.
