The markdown parsing is broken/disabled for release notes. Sorry about that, I'm chasing the source of a crash that's been bringing this website down for the last couple of days.
## Back pressure
This release improves support for back pressure, contributed by @kdubb. Client streams will match the rate at which gRPC is able to send requests to the server. Server streams will be buffered.
## Breaking changes
This release updates upstream Swift gRPC to v1.13.0. Note that you will need to use the -`NIOClient` versions of the generated Swift gRPC clients. For example, while you previously used:
```swift
let echoClient = EchoServiceClient(channel: channel)
```
You now have to use:
```swift
let echoClient = EchoServiceNIOClient(channel: channel)
```
