This is Excellent! Google Adsense has rolled out some new cool features into the AdSense management interface, which will enable the publisher to change the parameters of the Adsense block right from within their own account without having to replace the code on the website. publishers can now also preview the look of the Ad in real time as they make any wanted changes, such as the colors and size. another option enables publisher to preview how the ad will actually look like on the site itself.

I have already tested and replaced the old codes on my site with the new, it may take about 10 minutes for the new code to implement, I have noticed though that the new code is smaller than the old one, which of course is great!

Overall, this is a excellent improvement and gives publishers more control and makes the process of managing their ads much easier, simpler and faster.
