-## Maintenance Policy
+`v0.47.15` is the last release of the `v0.47.x` line. Per this version, the v0.47.x line reached its end-of-life.
+The SDK team maintains the [latest two major versions of the SDK](https://github.com/cosmos/cosmos-sdk/blob/main/RELEASE_PROCESS.md#major-release-maintenance). This means no features, improvements or bug fixes will be backported to the `v0.47.x` line. Per our policy, the `v0.47.x` line will receive security patches only.
 
-v0.50 has been released which means the v0.47.x line is now supported for bug fixes only, as per our release policy. Earlier versions are not maintained.
