Version Bump

-Added: List.indexedIterator which allows you to create a iterator with a customized iteration indecies. Useful if you want to transform lists output.
-Added: PriorityQueue.contains is now a function
-Added: Iterators/Async Builders now support MapToPrimitiveType function on the object variant. So more processing can be done. (Will be expanded upon later versions)
-Updated: SimpleCodeGenerator 1.3.0 is now being used which allows for iterative code support.

 # Changelog of versions
 
-### Version 0.7.1 (Unreleased)
+### Version 0.8.1
+- Added: getFirst/getLast/removeFirst/removeLast to List.class.
+- Added: Dedicated Set toArray implementations.
+- Added: ToArray/pushTop functions to Stack.class.
+- Added: ComputeNonDefault functions which will contain the current behavior of the Compute function, while the Compute will be changed to be more java compliant!
+- Added: List.reversed, which returns a SubList that has all elements in reversed order and also inserts reversed.
+- Added: Iterators.infinite as an option that will create a Infinite Iterator based on the inputed one.
+- Added: List.indexedIterator which allows you to create a iterator with a customized iteration indecies. Useful if you want to transform lists output.
+- Added: PriorityQueue.contains is now a function
+- Added: Iterators/Async Builders now support MapToPrimitiveType function on the object variant. So more processing can be done. (Will be expanded upon later versions)
+- Fixed: SetValue wasn't working on forEach implementations.
+- Fixed: Compute functions now perform with primitives more java compliant. Meaning that getDefaultReturnValue function no longer is seen as null.
+- Fixed: Supplier was using the wrong dataType in their function name.
+- Updated: SimpleCodeGenerator 1.3.0 is now being used which allows for iterative code support.
+
+### Version 0.8.0
+- Added: getFirst/getLast/removeFirst/removeLast to Lists
+- Added: Dedicated implementations for toArray into TreeSets
+- Fixed: forEach methods in Maps now can use "setValue" functions.
+
+### Version 0.8.0
 - Added: ISizeProvider interface (Optimization Helper)
 - Added: ISizeProvider into most Iterable implementations (Distinct/Filter/FlatMap/ArrayFlatMap don't support it, for obvious reasons)
 - Added: ToArray function into Iterable which uses ISizeProvider to reduce overhead of duplicating arrays.
+- Added: Functions that have the same type, Int2IntFunction as example, have now a identity function.
+- Added: Functions of a BooleanValue have now alwaysTrue/False function.
+- Added: ForEachIndexed for all Iterable implementations
+- Added: RandomGenerator support (Java17), though requires self compilation
+- Added: Optimizations for HashUtils next power of function.
+- Added: toArray() now returns a cached empty array if the collection is empty.
+- Added: toArray function for AsyncBuilder
+- Added: Modularization to the library where feature can be disabled as needed. (Requires Self-Compilation)
 - Fixed: putIfAbsent now replaces defaultValues
 - 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
+- Breaking Change: Classes that used PrimitiveCollection functions now default to java functions where applicable, this is to increase compat.
+- Breaking Change: Some function classes now get closer to javas terms. (Predicate/UnaryOperator etc)
 
 ### Version 0.7.0
 - Added: Over 11 Million Unit Tests to this library to ensure quality.

+### Extra Features
+
+Primitive Collections comes with a few extra features that are disabled by default.    
+These will be enabled as soon they become relevant or never at all.
+
+But some of these can be already unlocked when the target version changes.    
+
+If you compile the library for yourself you will automatically gain access to said features.
+
+### Java17 Exclusive Features    
+Java17 has some new features that can sadly not really be back-ported but the library still supports them if it is compiled with java17
+ 
+- RandomGenerator: Java17 has added [RandomGenerator.class](https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/util/random/RandomGenerator.html).
+  This allows to use custom random implementations without having to re-implement them yourselves.
+
+
+### ModuleSettings
+Primitive Collections is a huge library.   
+But maybe you only use like 5-10 different classes.   
+Normally you would use tools like "Proguard" to get rid of classes that you don't use.    
+But since a lot of classes have dependencies on each other this would only do so much.    
+
+This is where the [ModuleSettings](ModuleSettings.json) come into play.   
+It allows you to turn of implementations as you wish and adjusts the code that everything still works.   
+
+There is 3 layers of control inside of the ModuleSettings.   
+- Modules directly at the top that turn off everything.   
+- Type Specific configurations, where you can for example turn of everything thats "Long" based.   
+- And then there is each type specific module settings.   
+
+Allowing for greater control without having to edit hundreds of lines of code.   
+On top of that:   
+Any Setting that isn't "Present" is counted as "Enabled".    
+So if you want to disable just 1 thing you can keep that 1 thing and delete the rest of the Setting.    
+It will still work as the same.    
+The default settings just come with everything so you can see what is controllable.   
+
+How to compile the Code with the ModuleSettings enabled:
+```
+/gradlew.bat generateLimitSource build -x test
+```
