-Get ready for v0.50.0 and start integrating with the next [Cosmos SDK](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.50.0-rc.0) release.
-Once the Eden release is out, as per our [maintenance policy](https://github.com/cosmos/cosmos-sdk/blob/main/RELEASE_PROCESS.md#major-release-maintenance) we will no longer support the v0.46.x line of the Cosmos SDK, apart from critical security fixes.
+`v0.46.16` is the last release of the `v0.46.x` line. Per this version, the v0.46.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 `v0.46.x` line. Per our policy, the `v0.46.x` line will receive security patches only.
+
+We encourage all chains to upgrade to Cosmos SDK Eden (`v0.50.0`), or the `v0.47.x` line.
