# July

## Select multiple Versions when creating an Evaluation

*July 30th, 2024*

Our Evaluations feature allows you to benchmark Versions of a same File. We've made the form for creating new Evaluations simpler by allowing the selection of multiple in the picker dialog. Columns will be filled or inserted as needed.

As an added bonus, we've made adding and removing columns feel smoother with animations. The form will also scroll to newly-added columns.

## Enhanced code Evaluators

*July 10th, 2024*

We've introduced several enhancements to our code Evaluator runtime environment to support additional packages, environment variables, and improved runtime output.

Runtime environment

Our Code Evaluator now logs both `stdout` and `stderr` when executed and environment variables can now be accessed via the `os.environ` dictionary, allowing you to retrieve values such as `os.environ['HUMANLOOP_API_KEY']` or `os.environ['PROVIDER_KEYS']`.

Python packages

Previously, the selection of Python packages we could support was limited. We are now able to accommodate customer-requested packages. If you have specific package requirements for your eval workflows, please let us know!
