There are two Google AdWords updates that readers should take note of.
First, AdWords Editor 5.0.1 has been released. The only change is a small one, but it may help users:
The four tabs for ads (text, image, local business, and mobile) are now grouped under a single 'Ads' tab. This release addresses a space issue that only affected some users. If you aren't experiencing any difficulty, it isn't necessary to upgrade.
Forum members recommend that you export all data before you upgrade because you'll lose your comments from doing the simple upgrade.
On a related note, Google AdWords will have systemwide maintenance on May 17th (Saturday) from 10AM until 2PM PST. Ads will run but the API will not.
