Change Log

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

Note: This is the main Changelog file for the Rust solver. The Changelog file for the Python interface (opengen) can be found in /open-codegen/CHANGELOG.md
