Google has announced that it has launched the newest version of the AdWords API: version 12. Release notes are here, but include the following new features:
- Conversion Optimizer support
- CPC bidding for placement-targeted ads
- Expanded code sample library
Version 11 will be discontinued on July 26, 2008, so if you're an AdWords API developer: upgrade soon rather than later.
Forum discussion continues at Google Groups.
