* Remove deprecated range update callbacks:
-visibilityDidChange:
-visibleStateDidChange:
-displayStateDidChange:
-loadStateDidChange:

* Remove -clearFetchedData

* Remove -cancelLayoutTransitionsInProgress

* Remve ASDisplayNode+Deprecated.h

* Remove ASLayoutRangeTypeRender and ASLayoutRangeTypeFetchData

* Remove -[ASTableView clearContents]

* Remove reloadDataImmediately

* Remove ASStaticLayoutSpec

* Remove ASDimensionDeprecated

* Remove optional -pagerNode:constrainedSizeForNodeAtIndex: delegate method in ASPagerDelegate

* Remove suppressesInvalidCollectionUpdateExceptions

* Remove -[ASCollectionViewLayoutInspector initWithCollectionView]

* Remove ASVideoPlayerNode.loadAssetWhenNodeBecomesVisible

* Update CHANGELOG

* Update license of ASLayoutSpecTests.m

* Update examples/PagerNode
