* fix SIMULATE_WEB_RESPONSE not imported #449
* Fix to make rangeMode update in right time
* This is for cases when CollectionNode is created in cell of another collectionNode, the interfaceState(say didEnterVisible) is not called as expected.
It's because interfaceCoalescing alter the time line and cause RangeController update before actual interface applied.
* Make our async deallocation functions take a double pointer, so we can be sure we've released before the queue drains
* Make it a class property
* Fix the return type
* Use a locker
* Improve release notes
