> [!WARNING]
> **DEPRECATED:** The Google Mobile Ads C++ SDK is *deprecated* as of June 17, 2024 and should not be adopted in projects that don't already use it. It will enter *End-of-Maintenance (EoM)* on June 17, 2025. Note that versions of the SDK released before the EoM date will continue to function, but no further bug fixes or changes will be released after the EoM date.

With the release of a new major 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.

## Timetable

> [!IMPORTANT]
> **Key Point:** Sunset of a version follows the [Android](https://developers.google.com/admob/android/deprecation.md.txt) and [iOS](https://developers.google.com/admob/ios/deprecation.md.txt) deprecation schedules. If either the Android or iOS dependency for a version is sunset, the entire version can be considered sunset.

The following table lists the specific deprecation and sunset dates for each
version.

| Versions | Status | Release date | Deprecation date | Sunset date | Migration guide |
|---|---|---|---|---|---|
| [v12.0.0 - 12.1.0](https://developers.google.com/admob/cpp/rel-notes.md.txt#12.0.0) | Deprecated | May 7, 2024 | June 17, 2024 | June 17, 2025 |   |

| [v9.1.0 and below](https://firebase.google.com/support/release-notes/cpp-relnotes#admob) | Sunset | Prior to June 2022 | June 28, 2022 | June 30, 2023 | [Get started](https://developers.google.com/admob/cpp/quick-start.md.txt) |

^1^ Versions 10.0.0 - 10.3.0
introduced a dependency on an old iOS that was sunset on
June 30, 2023. Upgrade to 11.0.0 or higher to avoid risk of disruption to ad
serving.

## Differences between supported, deprecated, and sunset

| Term | Supported | Deprecated | Sunset |
|---|---|---|---|
| **SDK Versions** | All releases that depend on an Android and iOS 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 version with major release N-2. | All releases that depend on an Android or iOS 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 is available through the [contact us form](https://support.google.com/admob/contact/contact_us_gma_sdk). | Technical SDK support is no longer provided for this version. You will be asked to validate the issue in a supported version to receive full support. | Technical SDK support is no longer provided for this version. 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.
