-## stacLint
-
-**deprecated**
-
-Enables or disables a feature that validates the STAC catalog when opening the "Source Data" popup.
-Validation uses the external service [staclint.com](https://staclint.com).
-
-Validation is automatically disabled in the following cases:
-- the host of a catalog is `localhost`, `127.0.0.1` or `::1`
-- [private query parameters](../README.md#private-query-parameters) have been set
-- `stacProxyUrl` is set
-
 ## historyMode
 
 ***build-only option***
