Previously, it got passed the weights only needed for CPR. Additionally those were passed with the parameter tree to the update method and constructor. Now the CPR constructor gets a function to use for recalculating the weights and the property is not changed. Unfortunately this means that the preconditioner creators of the factory get another parameter.
