Due to some technical issues, we’ve decided to delay the release of v11 (originally planned for this week) for a few more weeks. While we could release some components of v11 now, we feel it is better to delay the entire release in order to minimize the number of versions we launch in a [...]

We will be performing unscheduled AdWords maintenance from 10 a.m. to 11 a.m. PT on Saturday, August 25, 2007. While all AdWords advertisements will continue to run as normal, you may not be able to perform API operations during this maintenance period.
We apologize for any inconvenience this may cause.

Late last night our engineers were able to implement the upgrades that were originally scheduled for this Saturday’s maintenance period. Therefore, we have canceled this weekend’s system maintenance. All systems will remain operational and available.

Over the past few weeks we have tested and implemented server enhancements that enable us to drive greater efficiencies from some of our more costly operations. Therefore, we are happy to announce the following rate sheet reductions:

addAds = 125 units (formerly 250)

We’re planning to refresh the Sandbox again tomorrow at 3 p.m. PDT. As a result, it’ll be unavailable for several hours and all associated data cleared. You can regenerate your client accounts afterwards by sending any valid request to the Sandbox without a clientEmail header block.

Just a reminder… per our announcement on April 20, we will shutdown version 9 of the API on August 20.
Please make sure to migrate your applications to version 10 by August 20. You can find more information about these versions (including the release notes) at http://www.google.com/apis/adwords/developer/index.html.

We apologize for any inconvenience this may have caused, and will notify you [...]
