+
+### Features
+
+* (runtime) [#19571](https://github.com/cosmos/cosmos-sdk/pull/19571) Implement `core/router.Service` it in runtime. This service is present in all modules (when using depinject).
+* (types) [#19164](https://github.com/cosmos/cosmos-sdk/pull/19164) Add a ValueCodec for the math.Uint type that can be used in collections maps.
+* (types) [#19281](https://github.com/cosmos/cosmos-sdk/pull/19281) Added a new method, `IsGT`, for `types.Coin`. This method is used to check if a `types.Coin` is greater than another `types.Coin`.
+* (client) [#18557](https://github.com/cosmos/cosmos-sdk/pull/18557) Add `--qrcode` flag to `keys show` command to support displaying keys address QR code.
+* (client) [#18101](https://github.com/cosmos/cosmos-sdk/pull/18101) Add a `keyring-default-keyname` in `client.toml` for specifying a default key name, and skip the need to use the `--from` flag when signing transactions.
+* (tests) [#17868](https://github.com/cosmos/cosmos-sdk/pull/17868) Added helper method `SubmitTestTx` in testutil to broadcast test txns to test e2e tests.
+* (client) [#17513](https://github.com/cosmos/cosmos-sdk/pull/17513) Allow overwriting `client.toml`. Use `client.CreateClientConfig` in place of `client.ReadFromClientConfig` and provide a custom template and a custom config.
+* (runtime) [#18475](https://github.com/cosmos/cosmos-sdk/pull/18475) Adds an implementation for core.branch.Service.
+* (baseapp) [#18499](https://github.com/cosmos/cosmos-sdk/pull/18499) Add `MsgRouter` response type from message name function.
+* (types) [#18768](https://github.com/cosmos/cosmos-sdk/pull/18768) Add MustValAddressFromBech32 function.
+* (gRPC) [#19049](https://github.com/cosmos/cosmos-sdk/pull/19049) Add debug log prints for each gRPC request.
+* (x/consensus) [#19483](https://github.com/cosmos/cosmos-sdk/pull/19483) Add consensus messages registration to consensus module.
+
+### Improvements
+
+* (server) [#19455](https://github.com/cosmos/cosmos-sdk/pull/19455) Allow calling back into the application struct in PostSetup.
+* (types) [#19512](https://github.com/cosmos/cosmos-sdk/pull/19512) The notion of basic manager does not exist anymore.
+    * The module manager now can do everything that the basic manager was doing.
+    * `AppModuleBasic` has been deprecated for extension interfaces. Modules can now implement `HasRegisterInterfaces`, `HasGRPCGateway` and `HasAminoCodec` when relevant.
+    * SDK modules now directly implement those extension interfaces on `AppModule` instead of `AppModuleBasic`.
+* (client/keys) [#18950](https://github.com/cosmos/cosmos-sdk/pull/18950) Improve `<appd> keys add`, `<appd> keys import` and `<appd> keys rename` by checking name validation.
+* (client/keys) [#18745](https://github.com/cosmos/cosmos-sdk/pull/18745) Improve `<appd> keys export` and `<appd> keys mnemonic` by adding --yes option to skip interactive confirmation.
+* (client/keys) [#18743](https://github.com/cosmos/cosmos-sdk/pull/18743) Improve `<appd> keys add -i` by hiding inputting of bip39 passphrase.
+* (client/keys) [#18703](https://github.com/cosmos/cosmos-sdk/pull/18703) Improve `<appd> keys add` and `<appd> keys show` by checking whether there are duplicate keys in the multisig case.
+    * Usage of `Must...` kind of functions are avoided in keeper methods.
+* (client/keys) [#18687](https://github.com/cosmos/cosmos-sdk/pull/18687) Improve `<appd> keys mnemonic` by displaying mnemonic discreetly on an alternate screen and adding `--indiscreet` option to disable it.
+* (client/keys) [#18684](https://github.com/cosmos/cosmos-sdk/pull/18684) Improve `<appd> keys export` by displaying unarmored hex private key discreetly on an alternate screen and adding `--indiscreet` option to disable it.
+* (client/keys) [#18663](https://github.com/cosmos/cosmos-sdk/pull/18663) Improve `<appd> keys add` by displaying mnemonic discreetly on an alternate screen and adding `--indiscreet` option to disable it.
+* (types) [#18440](https://github.com/cosmos/cosmos-sdk/pull/18440) Add `AmountOfNoValidation` to `sdk.DecCoins`.
+* (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.
+* (rpc) [#17470](https://github.com/cosmos/cosmos-sdk/pull/17470) Avoid open 0.0.0.0 to public by default and add `listen-ip-address` argument for `testnet init-files` cmd.
+* (types) [#17670](https://github.com/cosmos/cosmos-sdk/pull/17670) Use `ctx.CometInfo` in place of `ctx.VoteInfos`
+* [#17733](https://github.com/cosmos/cosmos-sdk/pull/17733) Ensure `buf export` exports all proto dependencies
+* (crypto/keys) [#18026](https://github.com/cosmos/cosmos-sdk/pull/18026) Made public key generation constant time on `secp256k1`
+* (crypto | x/auth) [#14372](https://github.com/cosmos/cosmos-sdk/pull/18194) Key checks on signatures antehandle.
+* (types) [#18963](https://github.com/cosmos/cosmos-sdk/pull/18963) Swap out amino json encoding of `ABCIMessageLogs` for std lib json encoding
+* (x/auth) [#19651](https://github.com/cosmos/cosmos-sdk/pull/19651) Allow empty public keys in `GetSignBytesAdapter`.
