Two weeks ago, Google Adsense promised a new feature, Coming soon: Make adsense changes without replacing code, that lets you easily manage your ad units from within your AdSense account. Now, they have started rolling out their new ad management feature to publishers! This feature will save the settings of your ad units within your AdSense account. That means, each time you want to change the colors, channels, or even the corner styles for your ad units, you can make the changes directly in your account rather than generating and pasting new code. Below are a few answers to questions you might have about this new feature:

How has the process of generating new ad code changed?

On the 'Get Ads' page of the 'AdSense Setup' tab, you'll find the same code generation wizard you've used before. At the end of the wizard, you'll now be prompted to provide a name for the ad unit you've just created. We recommend using a descriptive name so that you'll remember where you pasted this ad unit. For instance, use names like "Homepage Leaderboard, example.com" or "Top 300x250, Sports pages."

Why do I need to name my new ad units now?

With this new feature, all your new ad code will have a name and an unique ad slot ID. This will help you remember them so you can make changes to them later directly on the 'Manage Ads' page. As noted above, please be as specific as possible when naming your ad units and include information such as location, ad size, and domain.

Will the old ad code on my sites still work?

Any ad code you've generated in the past will continue to work as normal. However, please note that the old ad code will not automatically be updated to include this feature. If you'd like to apply this new feature to your old ad units, you can import the code and save the new settings.

Why don't I see anything after adding a new ad unit to my site?

If you're implementing a newly created ad unit on your site, the ad unit may not appear for up to 10 minutes while our servers are informed about the settings for the new unit. Don't feel like waiting? Simply use the Preview function on the 'Manage Ads' page to check out your updated pages immediately.

I made some changes to my ads, but nothing changed on my site. What happened?

Just as noted above, any changes to the ad unit may take up to 10 minutes to be visible. Feel free to use the Preview function to see your changes immediately.

How do I change the size of my ad units on the 'Manage Ads' page?

Unfortunately, size is one of the few things you can't change with this new feature. To change the size of your ads, you'll need to visit the 'Get Ads' page to generate a new ad unit.

How do I delete some of the ad units I created?

Right now, it isn't possible to delete ad units from within your account. This is designed to help avoid instances where an active ad units might be accidentally deleted. However, ad units that have not generated impressions for 7 days will become 'inactive' and will automatically be hidden. You can check the 'Show inactive AdSense units' box to unhide them.

Google Adsense will launch a new feature that lets you easily manage your ad units from within your AdSense account. Sound great!

Here is an official news from Google Adsense Blog, Coming soon: Make ad changes without replacing code:

We're very excited to let you know about an upcoming feature that lets you easily manage your ad units from within your AdSense account. It isn't live yet, but here's a sneak peek so you'll know what to expect in the coming weeks. (We know many of you have been eagerly anticipating its arrival.)

This new ad management feature means that your ad unit settings (such as colors and channels) for new AdSense for content ad units will be saved in your AdSense account every time you generate ad code. Then, if you'd like to change any of these settings in the future, all you do is make the update within your account -- you'll no longer need to manually replace the ad code on all of your pages. For instance, you can quickly change the borders of all your 300x250 medium rectangles from red to blue with just a few mouse clicks. Fancy! We hope that this new feature will help you save time and will simplify the process of optimizing your ad units.

As we noted above, please keep in mind that the ad management feature isn't yet available in any publisher accounts. We'll be rolling it out in phases in the next few weeks, and we'll follow up with another post at that time to help you better understand how to use the feature. When you see the "Manage Ads" page appear under your AdSense Setup tab, you'll know the feature is available for you to use.

Here's what it will look like:
