At the end of September 2012, new major versions of the AdWords API will be released according to a published schedule, "these major releases will occur 3 times per year: at the end of February, in the middle of June and at the end of September," posted AdWords API Team.
"Each new major release will trigger the deprecation of the previous major release. Exact deprecation timelines will be announced with each major release.
Exact release dates may vary."
"A major release is one that starts the sunset clock on previous releases," Mandy Waite stated. An example of this is the recent v201206 release which started the sunset clock on the v201109 and v201109_1 releases.
He says, Google will also continue to release minor versions to deliver new features as required. "Minor versions are optional and are source code compatible. Minor versions are delivered as dot releases and an example of this is the v201109_1 dot release," explains Waite.
In other post, Google explain the AdSense policies regarding copyrighted material and some tips on how to comply. Per Google blog post:
It's against our policies to show ads alongside copyrighted material you don't have authorization to use. Simply put, you cannot run AdSense ads alongside copyrighted content that violates copyright laws, or alongside links to such content. The program policies go into more detail.
Linking to filesharing hosts
It's against our policies to show ads on the same page as links to other sites that are hosting copyrighted materials without authorization. Keep in mind that these sites come in various forms such as forums, blogs or community websites.
Right to use the material?
In most cases, without a specific license or exception, you don't have the right to offer most mainstream entertainment such as television shows, movies, and popular music on your website.
If you created the content entirely from scratch, chances are you hold the copyright. Generally, you're free to monetize this kind of content any way you like. If you didn't create the content, or you created it using other peoples' content as source material, you should ask yourself if you have a license or if an exception applies.
You may have acquired permission from the copyright holder for the material on your web site. This kind of permission is typically called a license. In this case, as long as your use is in line with the license you have, you should be okay.
There are also exceptions to copyright law that may apply to your use. Fair use in the United States, and other similar exceptions elsewhere, allow for certain kinds of uses of copyrighted material. Common examples are criticism or scholarship. There are other exceptions to copyright law as well.
We don't want AdSense used in ways that may support copyright violations, so we sometimes err on the side of caution if a site cannot demonstrate a clear legal basis for using or linking to copyrighted material.
