Your services API playgrounds now have a new "Cache debug sidebar":

It contains the information that was previously at the bottom of the playground (cache result, maxAge, swr) and some new information as well:

• Cache miss reason: sometimes, requests can be MISSes for reasons outside of GraphCDNs control. For example, if your origin server sends back a Set-Cookie header we cannot cache the response.
• Cache scopes: all the scopes your rules applied to the query.
