 # @smooai/fetch
 
+## 3.4.0
+
+### Minor Changes
+
+- 2c20134: Rust: optional `otel` feature that injects W3C trace context (`traceparent`) into
+  every outbound request, so a call made through this client continues the caller's
+  trace instead of starting a new root. Off by default — the crate does not link
+  OpenTelemetry unless you ask for it. Guards an invalid span context and never
+  overwrites a `traceparent` the caller set explicitly.
+
+    TypeScript: the same injection at the same place — the single-request site, so every
+    retry carries a current traceparent — behind an optional `@opentelemetry/api` peer
+    dependency. Without it installed (or without a registered SDK) it is a no-op, not a
+    crash, and no all-zero `traceparent` is ever emitted.
+
+    Python: the same injection at the same place — the single-request site, so retries carry
+    a current traceparent — behind an optional `smooai-fetch[otel]` extra. Without
+    `opentelemetry-api` installed it is a no-op, not an import error.
+
+    Go: the same injection at the same place — `executeHTTPRequest`, the single-request
+    site inside the retry/timeout/breaker wrappers, so every attempt carries a current
+    traceparent. Uses the OTel global propagator, which defaults to a no-op, so a
+    service that never configured one sends nothing extra. Never overwrites a
+    caller-set `traceparent`, and emits nothing at all when there is no valid span
+    context.
+
+    .NET: no change needed — `HttpClient`'s `DiagnosticsHandler` already injects
+    `traceparent` from the current `Activity`, ahead of redirects and connection
+    pooling, and this client keeps that handler chain intact. Tests were added to pin
+    that behaviour so a future custom primary handler cannot silently drop it.
+
