 - API Addition: Added Group#removeActorAt(int,boolean) to avoid looking up the actor index. Subclasses intending to take action when an actor is removed may need to override this new method.
 - API Change: If Group#addActorAfter is called with an afterActor not in the group, the actor is added as the last child (not the first).
 
+[1.9.10]
+- API Change: InputProcessor scrolled method now receives scroll amount for X and Y. Changed type to float to support devices which report fractional scroll amounts. Updated InputEvent in scene2d accordingly: added scrollAmountX, scrollAmountY attributes and corresponding setters and getters.
 [1.9.9]
 - API Addition: Add support for stripping whitespace in PixmapPacker
 - API Addition: Add support for 9 patch packing in PixmapPacker
