# format_sdk_age_suffix

> **Function** in `deepagents_cli`

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

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

The `", "` separator is included so callers can splice the age into a
line unconditionally — if the age is unknown, the empty string
collapses cleanly into the surrounding text. May trigger a single
PyPI fetch on cache miss.

## Signature

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