This is a pretty tiny update with very little changed. Recommended to update from 1.16.2 ASAP as 1.16.2 is now no longer supported. Plugins should mostly remain working as the NMS revision did not change.

Subject: [PATCH] Optimize isValidLocation, getType and getBlockData for
|
|
inlining
|
|
|
|
Hot methods, so reduce # of instructions for the method.
|
|
|
|
Move is valid location test to the BlockPosition class so that it can access local variables.
|
|
|
|
Replace all calls to the new place to the unnecessary forward.
|
|
|
|
Optimize getType and getBlockData to manually inline and optimize the calls
