+### Scroll APIs need to send scroll_id in request body
+
+Sending the `scroll_id` as a parameter has been deprecated since version 7.0.0. It needs to be specified in the request body for `clear_scroll` and `scroll`.
+
+**Impact**<br>
+
+Client code using `clear_scroll` or `scroll` APIs and the deprecated `scroll_id` as a parameter needs to be updated.
+
+**Action**<br>
+
+If you are using the `clear_scroll` or `scroll` APIs, and sending the `scroll_id` as a parameter, you need to update your code to send the `scroll_id` as part of the request body:
+```ruby
+# Before:
+client.clear_scroll(scroll_id: scroll_id)
+# Now:
+client.clear_scroll(body: { scroll_id: scroll_id })
+
+# Before:
+client.scroll(scroll_id: scroll_id)
+# Now:
+client.scroll(body: { scroll_id: scroll_id })
+```
