+**Bug fix:**
 
 - Fixed a bug where :meth:`~glum.TweedieDistribution._rowwise_gradient_hessian` and :meth:`~glum.TweedieDistribution._eta_mu_deviance` would call functions with wrong arguments in the ``p = 3`` case.
 - Fixed :class:`glum.InverseGaussianDistribution` not using the optimized gradient, Hessian and deviance implementations, as well as those derivatives having the wrong sign.

 - Fixed a bug where :meth:`glum.GeneralizedLinearRegressor.fit` would raise a ``dtype`` mismatch error if fit with ``alpha_search=True``.
 - Use data type (``float64`` or ``float32``) dependent precision in solvers.
