v4.0

• implemented the QSA models where only dark matter is coupled to scalar field
• added background model based on parameterization of the DE density Omega_x, as opposed to w
• implemented a non-parametric reconstruction of mu, Sigma and Omega_x based on cubic-spline interpolation
• implemented the direct mu, Sigma parametrization for different models
• the option of including DE perturbations to achieve the consistency with CAMB when working with non-LCDM background models.
• added a python wrapper to run MGCAMB from the python interface
• the code has been restructured and upgraded to CAMB version 1.3.5
• added compatibility with Cobaya (MGCobaya)

v3.0

• implemented consistently massive neutrinos and dynamical dark energy.
• restructured and updated to the CAMB 2018 version.
