Today we released version 4.0 of AdWords Editor, our free, downloadable campaign management application. Version 4.0 includes support for mobile ads, the ability to post changes to selected campaigns, custom date ranges for performance statistics, and the ability to update negative keywords along with your regular keywords. You can read the release notes for a list of all the changes in version 4.0.

With the release of version 4.0, AdWords Editor is now available in 23 languages. The six new languages for version 4.0 are: Czech, Hebrew, Polish, Portuguese (Portugal), English (Australia), and Turkish.

If you haven't yet downloaded AdWords Editor, visit the AdWords Editor website to get the latest version. If you're already using AdWords Editor, you'll be prompted to upgrade automatically. To avoid losing unposted changes or comments, we suggest exporting an archive of your account before upgrading. After you've completed the upgrade, you just need to download your account and import the archive file to get your account up and running.

We encourage you to upgrade to version 4.0 within the next two weeks to avoid potential technical problems that might prevent older versions from being fully functional. While this release is for Windows only, version 4.0 will be available for Macs in the near future.
