Important Summary

Some bug fixes, some refinements to existing behaviour.

A pretty big new feature is that the SpecificEntropy profile class no longer behaves exactly like the HydrostaticMass profile class - in that it no longer requires you to calculate the entropy profile from fitted models to temperature and density, you can now use data points to calculate entropy as well, which is preferable. There are also models that can be fit to SpecificEntropy profiles, and you can use projected temperature profiles to calculate entropy if you wish.

The other new feature worthy of note is the addition of 'data driven' density profile calculation for galaxy clusters from surface brightness profiles. In addition to the existing 'inv_abel_fitted_model', which requires that a smooth model be fit to the surface brightness and then deprojected, you can now apply deprojection (inverse abel transforms) directly to data points - this can preserve interesting structure in the brightness profiles.

However, the biggest change is that we have finally updated all of the dependencies, and you will need to create a new environment to use this version of XGA. This was neglected for some years and it was becoming difficult to actually install XGA - that should now no longer be a problem, and if you visit the documentation site you will see instructions on how to use the newly included conda files to easily setup a compatible environment. We also aim for this to be the first release of XGA to be distributed through conda.
