Hey, Tracetest Community! How’s the beginning of 2024 treating you!?

I have a lot of cool updates to share with you today. Take a look at what's happened in the last month. 👇

## Hot tip of the day!

**Use the new “contains” operator!**

While filtering multiple span selectors at once can yield broader results, it can also become verbose quickly. Using the "contains" operator can help reduce this complexity.

[**👉 Check it out for yourself in the OpenTelemetry Demo environment!**](https://app.tracetest.io/organizations/ttorg_2179a9cd8ba8dfa5/invites/invite_7204842ee8f03fb8/accept)


## What’s New with Tracetest 🎉

[Tracetest Core v0.16.0](https://github.com/kubeshop/tracetest/releases/tag/v0.16.0) was released with new user experience and ease-of-use improvements!

**Handling >1000 spans.** The latest update adds major performance improvements in the UI. The trace viewer will now default to a timeline view when there are more than 200 spans.


**Use external integrations in the test creation flow.** Want to trigger a test with Cypress or Playwright? You can see how directly from the UI.


**Dashboard in Tracetest Agent CLI.** You get better developer experience by seeing which environment you’re connected to, what test is running, and which trace spans are ingested.


## Integrations 🤝

**Playwright Integration**. Test your critical flows with Playwright and leverage both OpenTelemetry and trace-based testing to verify your entire front end AND back end. True end-to-end testing in one Playwright test!

## Community Highlights

**Upcoming Conferences.**

**KubeCon + CloudNativeCon Europe 2024:** Tracetest will be at KubeCon Europe in Paris throughout March 20-22, 2024.
