+# Changelog of versions
+
+### Version 0.5.0
+- Added: 2 Helper functions to find out how many bits are required to store a Number.
+- Added: pour function directly into Iterable which allows to collect all elements in the Iterable directly.
+- Added: The new ToArray method from Java9 and newer into the library. Using a functional interface. (Just a backport)
+- Changed: Reworked how the Map Builder functions are created. They are now in a SubClass that moves them out of the way. Less Clutter. (This might break things if that was used before)
+- Added: Map Builder that allows now to Build Maps like Guava ImmutableMaps can be build. Note: This has a slight performance overhead.
+- Added: Unmodifiable and Synchronize wrapper functions direclty into Collection Interfaces. This is mostly a quality of life thing.
+- Added: Unmodifiable and Synchronized Wrapper Collections can now be cloned. They clone the underlying map which doesn't break functionality. (Had a usecase for it)
+- Added: A boxed putAll array variant.
+- Fixed: EnumMaps didn't keep track of their size and now got proper care and implementations as needed. There might be more work required but at least the core functionality is now up to date.
+- Added: Tests for the new Stream replace functions to ensure no bugs are left.
+- Fixed: Custom HashSet reduce function with a default value was checking incorrectly for present keys.
+- Added: Guava TestSuit
+- Fixed: HashCode and toString method would crash if the Object Key/Value was null
+- Added: AbstractTypeCollection now delegates the contains check to type-specific Collections if it detects it.
+- Fixed: Map.Entry toString wasn't writing values not like it should do.
+- Fixed: Set.hashCode now is the sum of the elements instead of a Unique HashCode based on the elements.
+- Fixed: Added missing NonNull Checks.
+- Fixed: Custom/OpenHashMap.containsValue implementation was wrong.
+- Fixed: Custom/OpenHashMap.compute/present/absent now works how it is specified in the Java Documentation
+- Fixed: Custom/OpenHashMap.merge/BulkMerge now works how it is specified in the Java Documentation
+- Fixed: Custom/Linked/OpenHashMap.keySet.remove was causing a infinite loop.
+- Fixed: Custom/Linked/OpenHashMap.entrySet.contains was not correctly comparing the entry.
+- Fixed: Custom/OpenHashMap.mapIterator now no longer crashes in certain cases.
+- Added: Custom/LinkedOpenHashMap now takes use of the improved Iterator it has for containsValue
+- Fixed: CustomOpenHashMap.keySet.forEach was basically putting out keys even if they were present
+- Fixed: ImmutableMaps issues thanks to the tests. Roughly the same as the rest of the maps
+- Fixed: RB/AVLTreeMaps issues. Roughly the same as the rest of the maps
+- Fixed: SubLists are now properly implemented.
+- Fixed: HashSet Iterator bugs now fixed... That was Painful.
+- Added: Tests for Lists and Sets
+
+### Version 0.4.5
+- Added: removeAll/retainAll(Collection c, Consumer r) which receives all the elements that got deleted from the collection
+- Fixed: Supplier get function wasn't referencing original function.
+- Added: addIfPresent/Absent to lists
+- Added: distinct, limit and peek iterators
+- Added: Iterable's can now reduce its contents
+- Added: Better ForEach support for IterableWrappers so a Iterator chain is not created
+- Added: SwapRemove to Lists which moves the last element into the desired space to be deleted
+- Added: More Test cases
+
+### Version 0.4.4

+- Added: FIFO Queue has now a minimum capacity and that is now checked more consistently.
+
+### Version 0.4.2
+- Added: Lists/Sets/Maps/PriorityQueues are now copy-able. with the new copy() function.
+	Note: subLists/subMaps/subSets or synchronize/unmodifyable wrappers do not support that function.
+- Fixed: PriorityQueues didn't implement: hashCode/equals/toString
+
+### Version 0.4.1
+- Changed: ForEach with input now provides input, value instead of value, input, this improves the usage of method references greatly

+- Fixed: ObjectLists Crashed when a null was provided as a Comparator. (Unless the List was Initialized with the ClassType)
+- Fixed: LinkedLists didn't implement add(Object)
+- Fixed: Object Collections did have the JavaCollections deprecated as the Constructor. This should only be deprecated for Primitives
+- Added: Tests with 5k Random names for Object sorting.
+- Changed: Object Arrays no longer require a Comparable[] it just assumes now that the elements in the Array are Comparable
+- Fixed: Dependency to SimpleCodeGenerator should be no longer a thing. Because the resulting library doesn't need it only the builder does.
+

+## Current Level of Stability
+Since this is a relatively new Library, stability was not perfect and some areas are not perfect yet.     
+Thanks to [ben-manes](https://github.com/ben-manes) we now have Roughly 16000 test covering Maps/Sets/Lists.     
+These tests cover Javas Collection API completely and ensuring a Stable implementation.     
+These freshly added tests allowed me to squash thousands of issues according to Googles Test Library (Guava-Tests).     
+These will be expanded on as time goes on.     
 
-The SourceCode can be already generated via: 
+One know aspect of Instability is SubSets and SubMaps. They require full rewrites to be fully stable.     
+So it is not advised to use them until these issues are addressed.     
+PriorityQueues are tested separately and ensure basic functionality though GuavaTests are planned.     
+They just require a custom test implementation.     
+
+As a summary: Stability is good/excellent, unless you need SubSets/SubMaps     
+
+## Specialized Functions
+New Specialized functions that were added to increase performance or reduce allocations or Quality Of life.
+To highlight things that may be wanted.
+- Iterable:
+	- map/flatMap/arrayFlatMap: A Light weight version of Stream.map().
+	- findFirst: Allows to find the first element of a Predicated Iterable.
+	- filter: Allows to filter unwanted elements for wrapped Iterable
+	- matchAny/matchNone/matchAll: Allows to find elements in a collection.
+	- count: counts all valid elements in a collection.
+	- forEach: Allows to input a second element into a forEach move allowing for more flexibility for Method References
+	- reduce/limit/peek/distinct: Light Versions of the Stream variant, to reduce Stream usage.
+	- pour: a function that allows to collect all elements within the Collection
+- Collection:
+	- containsAny: Allows to test if another collection contains an of the elements of the tested collection.
+	- primitiveStream: Provides access to the closest Java Stream Type.
+	- copy: shallowCopies the collection, used instead of clone because this is better to use.
+		(subCollections not supported for obvious reasons)
+	- toArray: the ToArray function from Java9 and newer that uses a Functional interface and can use a method reference
+- List:
+	- add/get/removeElements (From FastUtil): Allows to add/get/remove an Array into/from a list. Just with less overhead
+	- extractElements: Allows to remove a Range of elements from the List and get what was removed.
+	- Unstable Sort(From FastUtil): Uses a faster but not stable sort (Quick-Sort as example) to sort the list.
+	- addIfAbsent/Present: adds a element only if absent/present in the list
+	- swapRemove: deletes a desired element and inserts the last element in its place instead of leftshifting elements.
+- SortedSet:
+	- addAndMoveToFirst/Last (From FastUtil but moved to Interface): Allows to add a element to the first/last position of a sorted set.
+	- moveToFirst/Last: Moves the desired element at the first/last position of the SortedSet.
+	- pollFirst/Last: Allows to poll the first/last element of the set.
+- Map:
+	- putAll: putAll but in Array form.
+	- putAllIfAbsent: Puts only the elements that are absent.
+	- addTo (Only Primitives Values) (From FastUtil but moved to Interface): allows to add to the value of a given key. If not present it will be added. (Accumulator)
+	- addToAll: Same as addTo but bulkVersion.
+	- removeOrDefault: removes a Element and if not present returns the default value instead of the present value.
+	- mergeAll: BulkVersion of Merge function.
+	- supplyIfAbsent: A Supplier based computeIfAbsent
+- Sorted Map:
+	- addAndMoveToFirst/Last (From FastUtil but moved to Interface): Allows to add a element to the first/last position of a sorted Map.
+	- moveToFirst/Last: Moves the desired element at the first/last position of the Map.
+	- getAndMoveToFirst/Last: gets the element and moves it to the first/last position. Replicating a Optional LinkedHashMap feature.
+	- pollFirst/LastKey: Allows to poll the first/last element.
+	- first/LastValue: Allows to get the first/last value from the Map.
+	
+	
+# Notes about Versions
+Any 0.x.0 version (Minor) can be reason for massive changes including API.     
+To ensure that problems can be dealt with even if it is breaking the current API.     
+Any breaking changes will be Documented (once 1.0 is released)     
+
+Also to save space every 0.0.x (Patch) that is 2 Minor Versions behind will be removed. 
+So if 0.5.0 is released every 0.3.x patch will be deleted, except for the last patch for that minor version.

+# Contributing
+If you want to contribute.      
+This project is created using gradle and java and my Template Library only. Nothing extra.      
+If you setup gradle the library will be downloaded automatically.      
+
+Where is everything stored?
+- Variables and ClassNames are define [here](src/builder/java/speiger/src/builder/GlobalVariables.java)
+- Templates are stored [here](src/builder/resources/speiger/assets/collections/templates)
+- Tests can be found [here](src/test/java/speiger/src/collections)
+
+Please if you want to contribute follow the [Rule-Sheet](RuleSheet.md). It keeps everything in line.
+
+
+# How to Build
+
+The SourceCode can be generated via:     
 /gradlew.bat generateSource      
-to build the jar     
+
+to build the jar:           
 /gradlew.bat build      
 do not combine the commands because they can not be executed at the same time.      
 
 ## Current Down Sides (Random order)
-- EnumMaps are only normal maps no Linked Support yet
+- SubMaps/Set implementation isn't perfect right now. This will be addressed slowly due to rewrites required.     
-- Testing for Sub Maps/Sets/Lists are only in a very basic way tested
 - Documentation is only present at the lowest level for most cases and needs a typo fixing.
