## What's New

May 10, 2024

**Sessions**

A session is a grouping of traces based on a session ID attribute. When building or debugging a chatbot application, being able to see groups of messages or traces belonging to a series of interactions between a human and the AI can be particularly helpful. By adding `session.id` and `user.id` as attributes to spans, you can:

* Find exactly where a conversation "breaks" or goes off the rails. This can help identify if a user becomes progressively more frustrated or if a chatbot is not helpful.

* Find groups of traces where your application is not performing well. Adding `session.id` and/or `user.id` from an application enables back-and-forth interactions to be grouped and filtered further.

* Construct custom metrics based on evals using `session.id` or `user.id` to find best/worst performing `sessions` and `users`.

## Enhancements

May 10, 2024

**Join Evals on Existing Traces**

* Send in latent evals through our Python SDK. They will be joined daily on spans with matching `span_ids`\*. \*The functionality is very similar to that of latent actuals or tags, but with Evals.

* Send in your evaluations through the new `log_evaluations` method in the new Python SDK `v7.16.1`.

**Programmatically Create Dashboards**

Replicate a particular set of widgets across various dashboards, clone an entire dashboard, or integrate dashboard creation into your automated onboarding workflows with more ease. [Learn more ->](/docs/ax/machine-learning/machine-learning/how-to-ml/dashboards/programmatically-create-dashboards)

**Homepage Refresh**

Designed to streamline your workflow, so you can hop right into tracking and troubleshooting your projects.
