-This release includes the migration to [CometBFT v0.34.27](https://github.com/cometbft/cometbft/blob/v0.34.27/CHANGELOG.md#v03427).
-This migration should be not be breaking for chains.
-From `v0.46.11`+, the following replace is *mandatory* in the `go.mod` of your application:
+This release includes few improvements and bug fixes.
+Notably, the [barberry security fix](https://forum.cosmos.network/t/cosmos-sdk-security-advisory-barberry/10825). All chains using Cosmos SDK v0.46.0 and above must upgrade to `v0.46.13` **immediately**. A chain is safe as soon as **33%+1** of the voting power has upgraded. Coordinate with your validators to upgrade as soon as possible.
+
+Additionally, it includes new commands for snapshots management and bootstrapping from a local snapshot (add `snapshot.Cmd(appCreator)` to the chain root command for using it).
+
+Did you know Cosmos SDK Twilight (a.k.a v0.47) has been released? Upgrade easily by reading the [upgrading guide](https://github.com/cosmos/cosmos-sdk/blob/release/v0.47.x/UPGRADING.md#v047x).
+
+Ensure you have the following replaces in the `go.mod` of your application:
 
 ```go
 // use cometbft
-replace github.com/tendermint/tendermint => github.com/cometbft/cometbft v0.34.27
+replace github.com/tendermint/tendermint => github.com/cometbft/cometbft v0.34.28
+// replace broken goleveldb
+replace github.com/syndtr/goleveldb => github.com/syndtr/goleveldb v1.0.1-0.20210819022825-2ae1ddf74ef7
 ```
 
-Additionally, the SDK sets its minimum version to Go 1.19. This is not because the SDK uses new Go 1.19 functionalities, but to signal that we recommend chains to upgrade to Go 1.19 — Go 1.18 is not supported by the Go Team anymore.
-Note, that SDK recommends chains to use the same Go version across all of their network.
-We recommend, as well, chains to perform a **coordinated upgrade** when migrating from Go 1.18 to Go 1.19.
-
 Please see the [CHANGELOG](https://github.com/cosmos/cosmos-sdk/blob/release/v0.46.x/CHANGELOG.md) for an exhaustive list of changes.
