+* (x/consensus) [#12905](https://github.com/cosmos/cosmos-sdk/pull/12905) Create a new `x/consensus` module that is now responsible for maintaining Tendermint consensus parameters instead of `x/param`. Legacy types remain in order to facilitate parameter migration from the deprecated `x/params`. App developers should ensure that they execute `baseapp.MigrateParams` during their chain upgrade. These legacy types will be removed in a future release.
+* (cli) [#13454](https://github.com/cosmos/cosmos-sdk/pull/13454) `sign-batch` CLI can now read multiple transaction files.

 ### Improvements
 
 * (auth) [#13460](https://github.com/cosmos/cosmos-sdk/pull/13460) The `q auth address-by-id` CLI command has been renamed to `q auth address-by-acc-num` to be more explicit. However, the old `address-by-id` version is still kept as an alias, for backwards compatibility.

 This guide provides instructions for upgrading to specific versions of Cosmos SDK.
 
+<<<<<<< HEAD
+=======
+## [Unreleased]
+
+### Simulation
+
+Remove `RandomizedParams` from `AppModuleSimulation` interface. Previously, it used to generate random parameter changes during simulations, however, it does so through ParamChangeProposal which is now legacy. Since all modules were migrated, we can now safely remove this from `AppModuleSimulation` interface.
+
+### gRPC
+
+A new gRPC service, `proto/cosmos/base/node/v1beta1/query.proto`, has been introduced
+which exposes various operator configuration. App developers should be sure to
+register the service with the gRPC-gateway service via
+`nodeservice.RegisterGRPCGatewayRoutes` in their application construction, which
+is typically found in `RegisterAPIRoutes`.
+
+### AppModule Interface
+
+Remove `Querier`, `Route` and `LegacyQuerier` from the app module interface. This removes and fully deprecates all legacy queriers. All modules no longer support the REST API previously known as the LCD, and the `sdk.Msg#Route` method won't be used anymore.
+
+### SimApp
+
+The `simapp` package **should not be imported in your own app**. Instead, you should import the `runtime.AppI` interface, that defines an `App`, and use the [`simtestutil` package](https://pkg.go.dev/github.com/cosmos/cosmos-sdk/testutil/sims) for application testing.
+
+#### App Wiring
+
+SimApp's `app.go` is now using [App Wiring](https://docs.cosmos.network/main/building-chain/depinject.html), the dependency injection framework of the Cosmos SDK.
+This means that modules are injected directly into SimApp thanks to a [configuration file](https://github.com/cosmos/cosmos-sdk/blob/main/simapp/app_config.go).
+The old behavior is preserved and can still be used, without the dependency injection framework, as shows [`app_legacy.go`](https://github.com/cosmos/cosmos-sdk/blob/main/simapp/app_legacy.go).
+
+#### Constructor
+
+The constructor, `NewSimApp` has been simplified:
+
+* `NewSimApp` does not take encoding parameters (`encodingConfig`) as input, instead the encoding parameters are injected (when using app wiring), or directly created in the constructor. Instead, we can instantiate `SimApp` for getting the encoding configuration.
+* `NewSimApp` now uses `AppOptions` for getting the home path (`homePath`) and the invariant checks period (`invCheckPeriod`). These were unnecessary given as arguments as they were already present in the `AppOptions`.
+
+#### Encoding
+
+`simapp.MakeTestEncodingConfig()` was deprecated and has been removed. Instead you can use the `TestEncodingConfig` from the `types/module/testutil` package.
+This means you can replace your usage of `simapp.MakeTestEncodingConfig` in tests to `moduletestutil.MakeTestEncodingConfig`, which takes a series of relevant `AppModuleBasic` as input (the module being tested and any potential dependencies).
+
+#### Export
+
+`ExportAppStateAndValidators` takes an extra argument, `modulesToExport`, which is a list of module names to export.
+That argument should be passed to the module maanager `ExportGenesisFromModules` method.
+
+### Protobuf
+
+The SDK has migrated from `gogo/protobuf` (which is currently unmaintained), to our own maintained fork, [`cosmos/gogoproto`](https://github.com/cosmos/gogoproto).
+
+This means you should replace all imports of `github.com/gogo/protobuf` to `github.com/cosmos/gogoproto`.
+This allows you to remove the replace directive `replace github.com/gogo/protobuf => github.com/regen-network/protobuf v1.3.3-alpha.regen.1` from your `go.mod` file.
+
+Please use the `ghcr.io/cosmos/proto-builder` image (version >= `0.11.0`) for generating protobuf files.
+
+### Transactions
+
+#### Broadcast Mode
+
+Broadcast mode `block` was deprecated and has been removed. Please use `sync` mode
+instead. When upgrading your tests from `block` to `sync` and checking for a
+transaction code, you need to query the transaction first (with its hash) to get
+the correct code.
+
+### Modules
+
+#### `x/gov`
+
+##### Minimum Proposal Deposit At Time of Submission
+
+The `gov` module has been updated to support a minimum proposal deposit at submission time. It is determined by a new
+parameter called `MinInitialDepositRatio`. When multiplied by the existing `MinDeposit` parameter, it produces
+the necessary proportion of coins needed at the proposal submission time. The motivation for this change is to prevent proposal spamming.
+
+By default, the new `MinInitialDepositRatio` parameter is set to zero during migration. The value of zero signifies that this 
+feature is disabled. If chains wish to utilize the minimum proposal deposits at time of submission, the migration logic needs to be 
+modified to set the new parameter to the desired value.
+
+#### `x/consensus`
+
+Introducing a new `x/consensus` module to handle managing Tendermint consensus
+parameters. For migration it is required to call a specific migration to migrate
+existing parameters from the deprecated `x/params` to `x/consensus` module. App
+developers should ensure to call `baseapp.MigrateParams` in their upgrade handler.
+
+Example:
+
+```go
+func (app SimApp) RegisterUpgradeHandlers() {
+ 	----> baseAppLegacySS := app.ParamsKeeper.Subspace(baseapp.Paramspace).WithKeyTable(paramstypes.ConsensusParamsKeyTable()) <----
+
+ 	app.UpgradeKeeper.SetUpgradeHandler(
+ 		UpgradeName,
+ 		func(ctx sdk.Context, _ upgradetypes.Plan, fromVM module.VersionMap) (module.VersionMap, error) {
+ 			// Migrate Tendermint consensus parameters from x/params module to a
+ 			// dedicated x/consensus module.
+ 			----> baseapp.MigrateParams(ctx, baseAppLegacySS, &app.ConsensusParamsKeeper) <----
+
+			// ...
+
+ 			return app.ModuleManager.RunMigrations(ctx, app.Configurator(), fromVM)
+ 		},
+ 	)
+
+  // ...
+}
+```
+
+The old params module is required to still be imported in your app.go in order to handle this migration. 
+
+##### App.go Changes
+
+Previous:
+
+```go
+bApp.SetParamStore(app.ParamsKeeper.Subspace(baseapp.Paramspace).WithKeyTable(paramstypes.ConsensusParamsKeyTable()))
+```
+
+After:
+
+```go
+app.ConsensusParamsKeeper = consensusparamkeeper.NewKeeper(appCodec, keys[upgradetypes.StoreKey], authtypes.NewModuleAddress(govtypes.ModuleName).String())
+bApp.SetParamStore(&app.ConsensusParamsKeeper)
+```
+
+### Ledger
+
+Ledger support has been generalized to enable use of different apps and keytypes that use `secp256k1`. The Ledger interface remains the same, but it can now be provided through the Keyring `Options`, allowing higher-level chains to connect to different Ledger apps or use custom implementations. In addition, higher-level chains can provide custom key implementations around the Ledger public key, to enable greater flexibility with address generation and signing.
+
+This is not a breaking change, as all values will default to use the standard Cosmos app implementation unless specified otherwise.
