+Subject: [PATCH] Configurable Alternative LootPool Luck Formula
+
+Rewrites the Vanilla luck application formula so that luck can be
+applied to items that do not have any quality defined.
+
+See: https://luckformula.emc.gs for data and details
+-----------
+
+The rough summary is:
+My goal was that in a pool, when luck was applied, the pool
+rebalances so the percentages for bigger items is
+lowered and smaller items is boosted.
+
+Do this by boosting and then reducing the weight value,
+so that larger numbers are penalized more than smaller numbers.
+resulting in a larger reduction of entries for more common
+items than the reduction on small weights,
+giving smaller weights more of a chance
+
+-----------
+
+This work kind of obsoletes quality, but quality would be useful
+for 2 items with same weight that you want luck to impact
+in varying directions.
+
+Fishing still falls into that as the weights are closer, so luck
+will invalidate junk more.
+
+This change will result in some major changes to fishing formulas.
+
+-----------
+
+I would love to see this change in Vanilla, so Mojang please pull :)

+Subject: [PATCH] Avoid Chunk Lookups for Entity/TileEntity Current Chunk
+
+In many places where we simply want the current chunk the entity
+is in, instead of doing a hashmap lookup for it, we now have access
+to the object directly on the Entity/TileEntity object we can directly grab.
+
+Use that local value instead to reduce lookups in many hot places.

-Subject: [PATCH] Configurable Alternative LootPool Luck Formula
-
-Rewrites the Vanilla luck application formula so that luck can be
-applied to items that do not have any quality defined.
-
-See: https://luckformula.emc.gs for data and details
------------
-
-The rough summary is:
-My goal was that in a pool, when luck was applied, the pool
-rebalances so the percentages for bigger items is
-lowered and smaller items is boosted.
-
-Do this by boosting and then reducing the weight value,
-so that larger numbers are penalized more than smaller numbers.
-resulting in a larger reduction of entries for more common
-items than the reduction on small weights,
-giving smaller weights more of a chance
-
------------
-
-This work kind of obsoletes quality, but quality would be useful
-for 2 items with same weight that you want luck to impact
-in varying directions.
-
-Fishing still falls into that as the weights are closer, so luck
-will invalidate junk more.
-
-This change will result in some major changes to fishing formulas.
-
------------
-
-I would love to see this change in Vanilla, so Mojang please pull :)

-
-In many places where we simply want the current chunk the entity

-to the object directly on the Entity/TileEntity object we can directly grab.
-
-Use that local value instead to reduce lookups in many hot places.

-a new chunk generation process to begin with, so saving them serves no benefit.
