• initial support for deploying Spin applications to Hippo (https://github.com/fermyon/spin/pull/353)
• a new Go SDK for building Spin components in TinyGo (https://spin.fermyon.dev/go-components)
• new mechanism for setting application and component configuration (https://spin.fermyon.dev/configuration)
• new command to simplify building multi-component applications (https://spin.fermyon.dev/developing)
