Here are the most relevant improvements we've made since the last release:

## 🔍 Opik Trace Analyzer Beta is Live!

We're excited to announce the launch of **Opik Trace Analyzer** on Opik Cloud!

What this means: faster debugging & analysis!

Our users can now easily understand, analyze, and debug their development and production traces.

Want to give it a try? All you need to do is go to one of your traces and click on "Inspect trace" to start getting valuable insights.

## ✨ Features and Improvements

* We've finally added **dark mode** support! This feature has been requested many times by our community members. You can now switch your theme in your account settings.
