Deprecation and sunset

AI-generated Key Takeaways

Newer Google Mobile Ads SDK versions may lead to earlier versions being sunset, where ad traffic is at risk of receiving no fill due to stopped ad serving.
A predictable deprecation schedule allows for planning SDK updates, reduces SDK size and bugs, and focuses engineering resources on newer SDKs and features.
The sunset of a Google Mobile Ads SDK Unity plugin version follows the Android and iOS deprecation schedules, and the entire Unity plugin version can be considered sunset if either dependency is sunset.
Supported SDK versions serve ads and receive technical support, deprecated versions still serve ads but have limited technical support, and sunset versions are at risk of not serving ads and do not receive technical support.

Select platform: Android iOS Unity Flutter

With the release of a new major Google Mobile Ads SDK version, earlier major versions may be given a sunset date. After an SDK version is sunset, ad traffic from that version is at risk of receiving automatic no fill due to stopped ad serving.

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 can focus more on support for newer SDKs and innovation of new SDK features.

Differences between supported, deprecated, and sunset

Term	Supported	Deprecated	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 at risk of not serving to this version. We will regularly review usage of all sunset versions going forward to consider disabling ad serving. The oldest versions with lower usage and higher maintenance costs will be targeted first. When ad serving is disabled, ad requests return a no fill with an error indicating that this version is sunset.
Support	Technical SDK support questions are welcomed on the Google Mobile Ads SDK developer forum.	Technical SDK support questions specific to this version are no longer supported on the Google Mobile Ads SDK developer forum. You will be asked to validate the issue in a supported version to receive full support.

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.
