• Implement vorticity tensor calculations, https://arxiv.org/abs/2106.08125
• Implement a new 3D initial condition based on nuclear thickness function, https://arxiv.org/abs/2203.15718
• Add new EoS support at finite muB (EoS from UH)
• Add a new transport coefficient class to have better control on QGP transport coefficient
• Implement automatic tests with analytic solution using Github Actions
• Adding example IP-Glasma initial density by @mrhheffernan in #3
• Specific version number is output at runtime
• Bug fixes
