    The connector now uses version 1.1.1i of the OpenSSL library. Previously, the connector used version 1.1.1g.

Resolved Issues The following issues have been resolved in Simba Snowflake ODBC Connector 1.4.1.

  • [SNOW-191] When the connector executes a PUT or GET command on a folder in the local file path, and the name of the folder includes Unicode characters, the connector returns a “Failed to read directory structure on disk, directory” error.

  • [SNOW-203] When the connector retrieves a ResultSet in Arrow format, it uses a large amount of memory.

  • [SNOW-208] On Windows, when the connector completes a GET or PUT command, it does not close the thread handles that it opened, eventually preventing any new tasks from executing.
