## Improving reproducibility

uv supports an `exclude-newer` field in the `tool.uv` section of inline script metadata to limit uv
to only considering distributions released before a specific date. This is useful for improving the
reproducibility of your script when run at a later point in time.

The date must be specified as an [RFC 3339](https://www.rfc-editor.org/rfc/rfc3339.html) timestamp
(e.g., `2006-12-02T02:07:43Z`).

```python title="example.py"
# /// script
# dependencies = [
# "requests",
# ]
# [tool.uv]
# exclude-newer = "2023-10-16T00:00:00Z"
# ///

import requests

print(requests.__version__)
```
