changePosition(double x, double y) sits alongside changePosition(Vector2 v).
Moving by an amount only worked when the amount was already a Vector2, even
though setPosition has taken two numbers all along. Sprites moved by a step
worked out on the spot had to build a throwaway vector first, or fall back to two
changeX/changeY calls.
The documentation for the transparency methods has also been corrected.
Stage.setTransparency claimed a range of [0...1]; it is [0...255], and it is
an opacity rather than a ghost effect — 255 is the fully solid sprite you start
with, and 0 is invisible. The reference examples for the four transparency
methods passed values that read as if the scale ran the other way.
