 ## Dependencies and Makefile
 
-:::warning
-A patch introduced in `go-grpc v1.34.0` made gRPC incompatible with the `gogoproto` library, making some [gRPC queries](https://github.com/cosmos/cosmos-sdk/issues/8426) panic. As such, the Cosmos SDK requires that `go-grpc <=v1.33.2` is installed in your `go.mod`.
-
-To make sure that gRPC is working properly, it is **highly recommended** to add the following line in your application's `go.mod`:
-
-```go
-replace google.golang.org/grpc => google.golang.org/grpc v1.33.2
-```
-
-Please see [issue #8392](https://github.com/cosmos/cosmos-sdk/issues/8392) for more info.

 This section is optional, as developers are free to choose their dependency manager and project building method. That said, the current most used framework for versioning control is [`go.mod`](https://github.com/golang/go/wiki/Modules). It ensures each of the libraries used throughout the application are imported with the correct version.
 
 Below, the `go.mod` of the [Cosmos Hub](https://github.com/cosmos/gaia) is provided as an example.
 
 ```go reference
-https://github.com/cosmos/gaia/blob/Theta-main/go.mod#L1-L20
+https://github.com/cosmos/gaia/blob/26ae7c2/go.mod#L1-L28
 ```
 
 For building the application, a [Makefile](https://en.wikipedia.org/wiki/Makefile) is generally used. The Makefile primarily ensures that the `go.mod` is run before building the two entrypoints to the application, [`appd`](#node-client) and [`appd`](#application-interface).

 The [`BeginBlock` ABCI message](https://docs.tendermint.com/master/spec/abci/abci.html#beginblock) is sent from the underlying Tendermint engine when a block proposal created by the correct proposer is received, before [`DeliverTx`](#delivertx) is run for each transaction in the block. It allows developers to have logic be executed at the beginning of each block. In the Cosmos SDK, the `BeginBlock(req abci.RequestBeginBlock)` method does the following:
