CAT 1.14.0

Testing MS Excel data

We support testing MS Excel data using our Excel@2 provider. 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! ❤️

All recently reported documentation-related feedback was addressed.

Security fixes

Snowflake reported a moderate severity vulnerability for their driver: weak temporary files permissions. 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!
