Full Changelog: 2.4.0...2.5.0

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

Full Changelog: 2.3.2...2.4.0

This release brings a bug fix for the issue described in #101. It also includes extended tests and docstring tests for the README, as well as dependency updates for the documentation builder.

Full Changelog: 2.3.1...2.3.2

Minor fix to ensure variables less than one are tracked where required for the ExactProdConstraint and MaxProdConstraint constraints.

Full Changelog: 2.3.0...2.3.1

This release brings three exciting improvements:

• Python Constraint now has an entirely new type of built-in constraints, allowing comparisons with variables on both sides (e.g. "x == y / z") to be evaluated much more efficiently.
• Constraint rewriting has been extended to include subtraction and division operators.
• Rewriting of restrictions with less-than or greater-than operators now supports floats as well.

In addition:

• Tests have been extended and amended to reflect changes introduced.
• Documentation has been extended and amended to reflect changes introduced.
• Various minor bugs have been resolved.
• Bump requests from 2.32.3 to 2.32.4 in /docs by @dependabot in #99

This release adds additional wheel binaries for older manylinux versions.
It also updates the dependencies for the documentation and brings an improved changelog and pyproject.

Full Changelog: 2.2.2...2.2.3

This update brings a bug fix for an issue where variable names of incomparable types would raise an issue, as described in #96.

Full Changelog: 2.2.1...2.2.2

This fix update adds Python version classifiers and adjusts the performance benchmarking threshold.
