BREAK EVERYTHING!
This release doesn't have any functionality change over version 1.8.0 however it changes virtually all of the uses of Integer to Long so it will break compilation of everything that depends on it. This was done because all numbers within Canvas are 64 bits and there have been several problems with people running into problems with Integers so rather than fix things one by one, we decided to just do everything and bump the major version number because it is such a breaking change.
