# SDK Deprecation Policy

SDK versions are valid for **two years** after the release date.

- Deprecated SDK versions may not return ads. Publishers are recommended to upgrade to the latest version of the SDK regularly.
- SDK versions older than two years may still operate if the revenue volume is significant but efforts will be made to move developers to newer SDKs.
- Once the revenue is below 1%, any SDK versions that meet the deprecation policy may be disabled at the discretion of the ad server team.
