# format_age_suffix

> **Function** in `deepagents_cli`

📖 [View in docs](https://reference.langchain.com/python/deepagents-cli/update_check/format_age_suffix)

Return `", released Nd ago"` for `version`, or `""` when unknown.

The `", "` separator is included so callers can splice the age into a
parenthetical unconditionally — if the age is unknown, the empty
string collapses cleanly into the surrounding text.

## Signature

```python
format_age_suffix(
    version: str | None,
) -> str
```
