if you used python the api in the 2.5x are changed a lot , if possibile try to use adapter pattern best practice in the effort to hide changed code to parts change-insensitive code, but that pattern never change the need to make a refactoring of portions of code,but simply try limit and hide ( if 2.49 then ... else if 2.51 then ... else if 2.56 then ...) the changes to only what need to be changed avoiding the change have impact on code that never be changed
