     Fixed Maces Cripple playing an extra anvil break sound that could not be disabled in sounds.yml (See notes)
     Fixed Super Breaker and Tree Feller mishandling durability on items with a custom max_damage component (See notes)
     Fixed Tree Feller ignoring durability damage changes made by other plugins via PlayerItemDamageEvent
+    Improved performance when players gain skill XP (See notes)
+    Improved performance when taking smelted items out of furnaces (See notes)
 
     NOTES:
     The mcmmo.perks.xp.25percentboost permission family now behaves like the 10, 50, and 150 percent variants; previously only mcmmo.perks.xp.25percentboost.all had any effect.
+    Gaining XP now does much less repeated work per gain, which reduces mcMMO's share of server thread time on busy servers; no behavior or config changes are involved.
+    Taking smelted items out of a furnace no longer searches the full server recipe list every time.
     Cripple now plays a single sound which can be adjusted or disabled with the CRIPPLE entry in sounds.yml.
     Items with a custom maximum durability (set through the max_damage item component by data packs or item plugins) previously could make super abilities stop working or appear to restore durability; ability durability loss now always uses the item's own maximum.
