- Updated datasets to support more flexible data schema, you can now insert items with any key value pairs and not just `input` and `expected_output`. See more in the SDK section below.
- Multiple small UX improvements (more informative empty state for projects, updated icons, feedback tab in the experiment page, etc).
- Fix issue with `\t` characters breaking the YAML code block in the traces page.

**SDK**:

- Datasets now support more flexible data schema, we now support inserting items with any key value pairs:

  ```python wordWrap
  import opik

  client = opik.Opik()
  dataset = client.get_or_create_dataset(name="Demo Dataset")
  dataset.insert([
      {
          "user_question": "Hello, what can you do ?",
          "expected_output": {
              "assistant_answer": "I am a chatbot assistant that can answer questions and help you with your queries!"
          }
      },
      {
          "user_question": "What is the capital of France?",
          "expected_output": {
              "assistant_answer": "Paris"
          }
      },
  ])
  ```

- Released WatsonX, Gemini and Groq integration based on the LiteLLM integration.

- The `context` field is now optional in the [Hallucination](/guides/overview-integrations-overview) metric.

- LLM as a Judge metrics now support customizing the LLM provider by specifying the `model` parameter. See more in the [Customizing LLM as a Judge metrics](https://www.comet.com/evaluation/metrics/overview#customizing-llm-as-a-judge-metrics) section.

- Fixed an issue when updating feedback scores using the `update_current_span` and `update_current_trace` methods. See this Github issue for more details.
