 ## [2.0a1] - 2023-08-20
 
 This release separates out casm/clexulator from CASM v1. It creates a Python package, libcasm.clexulator, that enables using casm/clexulator and may be installed via pip install, using scikit-build, CMake, and pybind11. This release also includes usage and API documentation for using libcasm.clexulator, built using Sphinx.
