+Hello @channel! :wave:
+
+Webiny 6.4.1 is out! :rocket:
+
+A quick patch release this time around. If you've been working with webhooks in API-only scenarios, you'll appreciate that we've made the payload verification helper accessible from the SDK. Previously this was tucked away and couldn't be imported directly — now it's right where you'd expect it. Check out the changelog to learn more.
