Added
Spans carry full request and response payloads
A function span now records its request headers and body, its response, and its input and output. Outbound HTTP spans carry their request and response, and database spans carry the query result. Spans previously held only summary fields such as method, route, and status, which told you that something failed without showing you what went into it. Payloads are size-capped and sensitive request headers are redacted.
