API Versioning Is Coming

Friday, January 13, 2006

Happy New Year to you all.

While I’m not thrilled that we kicked the year off with a quota calculation bug (which has long since been fixed), I am very excited to pre-announce the release of API versioning.

API versioning allows Google to release new functionality, and modify existing functionality, without disrupting our developers' code. Therefore, you will no longer have to worry about "breaking" releases and just-in-time upgrades. You simply write your code for a specific version of the WSDL and it will continue to operate as normal even after we release new versions. You then will have several weeks to update and test your new code before you officially upgrade to a newer version.

We plan to release versioning later this month in conjunction with our new Content Bidding functionality. At that time we will update our Developer's Guide to reflect the technical details and policies regarding versioning.

And please note: since Content Bidding will be included in a new “version” of the API, this release will not disrupt your current API clients.

We hope you find this new functionality helpful, and we’ll share more details on this release as soon as possible.
