Templated Environment Variables
Custom variables can now be dynamically composed of other variables using the syntax ${{ OTHER_VARIABLE }}! This can both reduce duplication and allow exposing plugin-provided variables under different names. Check out the Templated Variables docs for some concrete examples.

CLI starters
The CLI now lists all the starters that are available on the website. Users can choose any starter they'd like and enter the required environment variables and we'll deploy the template for them along with the required plugins.
