Portion of diff was dropped in the mappings update commit. Also remove the option to remove invalid statistics. The server will automatically do this now as of... 1.13?, our option wasn't even doing anything.

Subject: [PATCH] Optimize Light Recalculations
|
|
|
|
The server triggers light recalculations even if the new block
|
|
is the same as the old block. At this time, BlockData Properties
|
|
do not impact light calculations.
|
|
|
|
So the only way light should change, is if the block itself
|
|
changes from 1 block to another.
|
|
|
|
Also optimizes to not repeatedly look up the same chunk for
|
|
light lookups.
