Deprecation and sunset

With the release of a new major Google Mobile Ads SDK version, a deprecated major version may be given a sunset date, after which all SDKs with that major version will no longer serve ads.

Benefits of a deprecation schedule

Introducing a predictable deprecation schedule offers the following benefits:

  • Ability to predict and plan for SDK updates with a year of lead time.
  • Legacy SDK code that only exists to support old versions can be deleted, thereby decreasing SDK size and lowering the risk of bugs.
  • Engineering resources are freed up to focus more on support for newer SDKs and innovation of new SDK features.

Timetable

The following table lists the specific deprecation and sunset dates for each Google Mobile Ads C++ SDK version.

Versions Release date Deprecation date Sunset date Migration guide

Differences between supported, deprecation, and sunset

Term Supported Deprecation Sunset
SDK Versions All releases that depend on an Android and iOS Google Mobile Ads SDK version with major release N or N-1, where N is the latest respective Android or iOS major version. All releases that depend on an Android or iOS Google Mobile Ads SDK version with major release N-2. All releases that depend on an Android or iOS Google Mobile Ads SDK version with major release N-3 or below. Releases with a dependency on an N-3 major version will sunset approximately two months after the major version N dependency is released.
Ad serving Ads serve to this version. Ads serve to this version. Ads will not serve to this version. Ad requests return a no fill with an error indicating that this version is sunset.
Support Technical SDK support questions are welcomed on the Firebase C++ SDK issue tracker. Technical SDK support questions specific to this version are no longer supported on the Firebase C++ SDK issue tracker. You will be asked to validate the issue in a supported version to receive full support. Sunset versions are no longer supported after the sunset date.

Exceptions

This deprecation schedule provides a framework for predictable lifetimes for an SDK version. However, there may be exceptions in the future. This schedule does not preclude us from sunsetting an SDK version at an earlier date, but we are committed to providing proactive communication with ample lead time for any future changes.
