We’d like to ask anyone still using AdWords Editor 2.0, 2.5, or 3.0 to upgrade to the latest version (3.5) before July 10, 2007. After July 10, versions 2.0, 2.5, and 3.0 will no longer be supported. To upgrade, just follow the automatic download prompt that appears whenever you start AdWords Editor. You can find instructions on how to preserve any comments or unposted changes when you upgrade here.
For a complete list of version-specific changes, see AdWords Editor Release Notes
