@@ -5,28 +5,43 @@ Subject: [PATCH] Heavily optimize recipe lookups in CraftingManager
 
 Recipe lookups are now cached in CraftingManager, which prevent unnecessary ArrayLists being created for every lookup. Additionally, an EMPTY_MAP variable was added to prevent bottlenecks during map creation, since that map is only ever iterated.
 
-GlueList was also used as a replacement for ArrayList as it is substantially faster.
-
 These changes knock off an extra ~10ms of tick duration with a sample of ~7,700 running furnaces on a server.
