 ### Improvements
 
+* (telemetry) [#18646] (https://github.com/cosmos/cosmos-sdk/pull/18646) Enable statsd and dogstatsd telemetry sinks
 * (types) [#18440](https://github.com/cosmos/cosmos-sdk/pull/18440) Add `AmountOfNoValidation` to `sdk.DecCoins`.
 * (x/gov) [#18025](https://github.com/cosmos/cosmos-sdk/pull/18025) Improve `<appd> q gov proposer` by querying directly a proposal instead of tx events. It is an alias of `q gov proposal` as the proposer is a field of the proposal.
 * (client) [#17503](https://github.com/cosmos/cosmos-sdk/pull/17503) Add `client.Context{}.WithAddressCodec`, `WithValidatorAddressCodec`, `WithConsensusAddressCodec` to provide address codecs to the client context. See the [UPGRADING.md](./UPGRADING.md) for more details.
