 - Fixed: OpenHashSet/Map and their Custom Variants no longer rely on List implementations.
 - Fixed: ObjectCopyOnWriteList.of did create a ObjectArrayList instead of the CopyOnWrite variant.
 - Removed: BooleanSet and Maps that start with a Boolean classes since they can not be used anyways.
+- Breaking Change: Function classes now use the "apply/applyAs/test" format from Java itself, instead of the "get" format. This cleans up a lot of things. But will break existing function class implementations
 
 ### Version 0.7.0
 - Added: Over 11 Million Unit Tests to this library to ensure quality.
