# Helix 0.72.0: Full payloads on traces

> Spans now carry the whole operation payload rather than summary fields, so a trace shows what was actually sent and returned. Sensitive headers are redacted.

- Released: 23 Jul 2026 (2026-07-23)
- Packages: @trayai/helix-sdk@0.72.0

## Headline changes

### 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.
