Things like brush size and strength accessors now take a scene parameter rather than guessing about which Scene's unified paint settings to use. Setting the size/strength through RNA can now be done separately for the brush or the UnifiedPaintSettings. The UI python code required updating to check whether the size/strength controls should use brush or UnifiedPaintSettings RNA. Radial control also required some updates to switch between the two RNA sources.
