 ### Improvements
 
+* (keyring) [#17913](https://github.com/cosmos/cosmos-sdk/pull/17913) Add `NewAutoCLIKeyring` for creating an AutoCLI keyring from a SDK keyring.
+* (codec) [#17913](https://github.com/cosmos/cosmos-sdk/pull/17913) `codectypes.NewAnyWithValue` supports proto v2 messages.
 * (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.
 * (crypto/keyring) [#17503](https://github.com/cosmos/cosmos-sdk/pull/17503) Simplify keyring interfaces to use `[]byte` instead of `sdk.Address` for addresses.
 * (all) [#16537](https://github.com/cosmos/cosmos-sdk/pull/16537) Properly propagated `fmt.Errorf` errors and using `errors.New` where appropriate.

+## Signing
+
+`autocli` supports signing transactions with the keyring.
+The [`cosmos.msg.v1.signer` protobuf annotation](https://github.com/cosmos/cosmos-sdk/blob/9dd34510e27376005e7e7ff3628eab9dbc8ad6dc/docs/build/building-modules/05-protobuf-annotations.md#L9) defines the signer field of the message.
+This field is automatically filled when using the `--from` flag or defining the signer as a positional argument.
+
+:::warning
+AutoCLI currently supports only one signer per transaction.

 ## Module Wiring & Customization
 
 The `AutoCLIOptions()` method on your module allows to specify custom commands, sub-commands or flags for each service, as it was a `cobra.Command` instance, within the `RpcCommandOptions` struct. Defining such options will customize the behavior of the `autocli` command generation, which by default generates a command for each method in your gRPC service.
