v2.0.0

Yeah, the new major release right after the first one.

This release fixes most of all the problems that were found in the first release. And introduces significant speedup 🚀. It is ~4 times faster than odiff v1 😱

Command	Mean [s]	Min [s]	Max [s]	Relative

Here is a list of changes:

Breaking changes

• --diff-image mode is default now, if you need to get the diff mask you can put the --diff-mask option or pass outputDiffMask: true to the node bindings

Features

• No more requirement of libpng. It is linked and provided together with the library, so it works out of the box even on Windows
• Using ourself C bindings to libpng which avoids any data copying and creates significant speed up.
• Support of .tiff and .xpm formats using appropriate C format libs
