Those new code will replace the old Show(Activity activity, int themeResId) which will possibly causes bug after upgrading to 3.3.0 example Maybe it would be better to create a new Show method to handle the fullscreen instead of replacing the old one.

Also, this change should have been considered a breaking change as 4.0.0
