v3.0.0

• Breaking: changed the API to accept options object literal (with threshold and includeAA properties) rather than arguments.
• Breaking: changed threshold to be relative to YUV distance (not squared); this means you'll have to change the threshold values you're currently using to sqrt(threshold).
• Added usage examples for Node & browsers in the readme.

v2.0.2

Increased accuracy of anti-aliased pixels comparison.

v2.0.1

Adds Node 0.10 support for command line and tests.

v2.0.0

• Much more accurate anti-aliased pixels detection algorithm #2
• Display transparent pixels as white rather than gray in diff

Note a breaking API change: antialiasing argument (number, 1 by default) is replaced with includeAA (boolean, false by default). Anti-aliasing detection is still enabled by default but always happens with 1 pixel radius.

v1.1.1

Fixed minor bug in color difference calculation.

v1.1.0

Use premultiplied Y'UV colorspace for color comparison, making it more in line with human perception of color.

v1.0.0

First release.
