This release brings support for negative values - an important feature that had long been latent and neglected, that is now actively developed and tested. Please report any issues you might run into.

This release also includes the following improvements:

• MinSumConstraint is now much faster thanks to preprocessing
• Variables values can be instantiated with any type that can be iterable, such as sets
• Two issues (#13 and#65) relating to the examples have been resolved
• Various minor improvements
