 ## [Unreleased]
 
 ### Client Breaking
+
 * (modules) [\#7243](https://github.com/cosmos/cosmos-sdk/pull/7243) Rename `RegisterCodec` to `RegisterLegacyAminoCodec` and `codec.New()` is now renamed to `codec.NewLegacyAmino()`
 * (cli) [\#6651](https://github.com/cosmos/cosmos-sdk/pull/6651) The `gentx` command has been improved. No longer are `--from` and `--name` flags required. Instead, a single argument, `name`, is required which refers to the key pair in the Keyring. In addition, an optional
   `--moniker` flag can be provided to override the moniker found in `config.toml`.

 ### Features
 
+* [\#7485](https://github.com/cosmos/cosmos-sdk/pull/7485) Introduce a new optional `--keyring-dir` flag that allows clients to specify a Keyring directory if it does not reside in the directory specified by `--home`.
 * [\#6755](https://github.com/cosmos/cosmos-sdk/pull/6755) Add custom regex validation for `Coin` denom by overwriting `CoinDenomRegex` when using `/types/coin.go`.
 * [\#7265](https://github.com/cosmos/cosmos-sdk/pull/7265) Support Tendermint block pruning through a new `min-retain-blocks` configuration that can be set in either `app.toml` or via the CLI. This parameter is used in conjunction with other criteria to determine the height at which Tendermint should prune blocks.
 * (vesting) [\#7209](https://github.com/cosmos/cosmos-sdk/pull/7209) Create new `MsgCreateVestingAccount` message type along with CLI handler that allows for the creation of delayed and continuous vesting types.
