# Changelog of versions
### Version 0.4.5
- Added: removeAll/retainAll(Collection c, Consumer r) which receives all the elements that got deleted from the collection
### Version 0.4.4
- Fixed: ObjectArrayList.of was causing crashes because of a Poor implementation.
- Added: Unsorted HashMaps/Sets now throw Concurrent exceptions if they were modified during a rehash.
