# CAT 1.14.0


## Testing MS Excel data

We support testing MS Excel data using our [Excel@2 provider](https://docs.justcat.it/reference/data-sources/providers/excel-2/ "Excel@2"). You reported problems when querying empty MS Excel sheets - the headers were incorrectly interpreted as data. We use DuckDB under the hood and a few days ago they released a brand new MS Excel extension that finally fixes that issue.

## Documentation updates

You provided tremendous amount of feedback on our documentation - thanks a lot for that! <span style="font-size: 18pt;">&#10084;&#65039;</span>

All recently reported documentation-related feedback was addressed.

## Security fixes

Snowflake reported a moderate severity vulnerability for their driver: <a href="https://github.com/advisories/GHSA-2mqw-rq5m-8hc8" target="_blank">weak temporary files permissions</a>. We carefully monitor such things for all technologies we support. Please update CAT regularly to get all security fixes.

-----------------------------------------

We are still working on a brand new version of CAT Studio. You'll soon be able to author automated tests for your data from a new app, without touching YAML or command line. Stay tuned.

That's it :-). Happy testing!
