+## [3.4.2] - 2022-06-14
+### Fixed
+- Updated fetch_r_script_checksum method in the CLI to iterate over multiple results batches within a single cursor. This protects against failure in the case where the R-script results are large enough to require multiple batches. Ref snowflake-python-connector documentation here: https://docs.snowflake.com/en/user-guide/python-connector-api.html#get_result_batches
+
 ## [3.4.1] - 2021-12-08
 ### Added
 - Added a new optional parameter `--query-tag` to append a string to the QUERY_TAG that is attached to every SQL statement executed
