 # OpenTelemetryDecorator
 
+## v1.4.9
+Adds the ability to pass links to a function decorated with `with_span` or `trace`. This is done by passing a `links` option to the decorator.
+The `links` option should be the atom names of variables containing linked spans. You can create a link to a span with `OpenTelemetry.link/1`
+
+e.g.
+```elixir
+require OpenTelemetry.Tracer, as: Tracer
+
+def parent do
+  parent_span = Tracer.start_span("parent")
+  link = OpenTelemetry.link(parent_span)
+
+  child(link)
+end
+
+@decorate with_span("child", links: [:parent_link])
+def child(parent_link) do
+  # ...
+  :ok
+end
+```

 ## v1.4.8
