With this release we are happy to announce the full protobuf migration of the Tendermint repo. This consists of changes that you may need to be aware of:
- All proto files have been moved under one directory, `/proto`. This is in line with the recommended file layout by [buf](https://buf.build), you can read more about it [here](https://buf.build/docs/lint-checkers#file_layout)
- We use the generated protobuf types for only on disk and over the wire serialization. This means that these changes should not effect you as user of Tendermint.
- A few notable changes in the abci:
- In `ValidatorUpdates` the public key type has been migrated to a protobuf `oneof` type. Since Tendermint only supports ed25519 validator keys this is the only available key in the oneof.

We will be making this possible by keeping the current types in there current form (handwritten) and creating a `/proto` directory in which all the `.proto` files will live. Where encoding is needed, on disk and over the wire, we will call util functions that will transition the types from handwritten go types to protobuf generated types.

By going with this design we will enable future changes to types and allow for a more modular codebase.
