+title: OpenTelemetry Demo 1.6 released
+linkTitle: Demo 1.6 Released
+date: 2023-11-07
+author: '[Austin Parker](https://github.com/austinlparker)'
+---
+
+The OpenTelemetry Demo has been updated to version 1.6, and introduces alpha
+support for the OpenTelemetry [Log signal](/docs/concepts/signals/logs/)!
+
+## Our thoughts on logs
+
+Why are we considering logging support to be in alpha? There are a few reasons.
+The most important is that this is the first time we've shipped the demo with a
+logging database. We chose [OpenSearch](https://opensearch.org/) as the storage
+backend for logs because it's a popular option that aligns with the project's
+license. It's worth noting that the demo doesn't require application-level logs
+— everything you care about is available as a span.
+
+Where logs shine is in bridging the gap between application traces and
+infrastructure, and over the next few releases, we plan to enhance this story by
+collecting Kubernetes, Envoy, and other logs relevant to the demo.
+
+If this sounds like an interesting problem, we'd love to have you as a
+[contributor](https://github.com/open-telemetry/opentelemetry-demo/blob/main/CONTRIBUTING.md)!
+We'd also appreciate any feedback you might have on how our support for logging
+can improve.
+
+## Other changes
+
+This release also includes some nice additions on the Kubernetes side -- you'll
+be able to increase the number of replicas per service, for instance. We've
+updated many dependencies throughout the project as well.
+
+## What's next?
+
+With the addition of logging, the demo is mostly feature-complete. However,
+there's more that can be done, and we're looking at a few major areas over the
+next months:
+
+- Increase the number of documented scenarios to demonstrate how OpenTelemetry
+  can be used to solve real-world problems.
+- Ensure that the demo reflects the OpenTelemetry feature matrix and that we're
+  showing off everything you can do with the project.
+- Improve our dashboards and add alerts, SLOs, and other observability features
+  to the demo.
+- Support other clients and front-end RUM features as they're released.
+
+As always, we'd love to hear your feedback on the demo, and if you're looking
+for a place to start contributing, the demo is a great place to get involved!
+
+Check out the
+[demo repository](https://github.com/open-telemetry/opentelemetry-demo) for more
+information, and to find the latest release.
