Changelog 2025 09 05

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

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.

• 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.

• Now you can filter the widgets in the metrics tab by trace and threads attributes

• Annotating tons of threads? We've added the ability to export feedback score comments for threads to CSV for easier analysis in external tools.
• We have also improved the discoverability of the experiment comparison feature.
• Added new filter operators to the Experiments table

• Adding assets as part of your experiment's metadata? We now display clickable links in the experiment config tab for easier navigation.

• We've released Opik University! This is a new section of the docs full of video guides explaining the product.

• Enhanced LangChain integration with comprehensive tests and build fixes
• Implemented new search_prompts method in the Python SDK
• Added documentation for models, providers, and frameworks supported for cost tracking
• Enhanced Google ADK integration to log error information to corresponding spans and traces
