For 2018, there will be three AdWords API releases:
On average, every AdWords API version released in 2018 will be available for approximately 9 months. For more details on the new release schedule, see this announcement.
With the release of a new version, a deprecated version is given a sunset date, after which that version will no longer be available. Our client libraries support all available versions of all services. You can gradually migrate by specifying different versions for different services.
The table below lists the specific deprecation and sunset dates for each available version, with links to the relevant announcement blog posts. We encourage you to migrate to the newest version as soon as feasible after its release.
