Spectral 7.x Upgrade Guide
Spectral 7.x is completely backwards-compatible with Spectral 6.x, so you can safely upgrade your version from 6.x to 7.x without changing your custom component code.
In Spectral 7.x, we focused on improving instance deployment. You can now create Data Sources. Like triggers or actions, data sources use connections to call third-party APIs and gather data. Data sources gather data that you can dynamically insert into config variables in an instance configuration wizard.
Read more about the instance configuration wizard here, and about writing your own data source here.
