## Subdomain Configuration

Connections can rely on separate subdomains for each function, allowing the support for multi-service architectures. A default subdomain must be provided, to be used for state management, and authentication detail validation.

Connector inputs can now be configured to respect specific encoding when being passed to your external systems. More information on this functionality is available [here](/r230/docs/connector-input-encoding-control).

## Small Improvements
