4.3.0

• v4.3.0(February 12,2026)
  • Ensured proper list conversion - the converter runs to_snowflake on all list elements.
  • Made the parameter server_session_keep_alive in SnowflakeConnection skip checking for pending async queries, providing faster connection close times especially when many async queries are executed.
  • Fix string representation of INTERVAL YEAR and INTERVAL MONTH types.
  • Log a warning when using http protocol for OAuth urls.
  • Deprecated support for custom revocation error classes in OCSP response cache deserialization. By default, only RevocationCheckError exceptions are deserialized from OCSP cache. Custom exception classes can be temporarily enabled by setting the SNOWFLAKE_ENABLE_CUSTOM_REVOCATION_ERRORS environment variable to true or 1, but this support will be removed in a future release.
  • Bumped up vendored urllib3 to 2.6.3
  • Added force_microseconds_precision to cursor.fetch_arrow_all and cursor.fetch_pandas_all to avoid PyArrow schema incosistency between batches.
