Release

1.37.0 (2025-08-18)

Snowpark Python API Updates

New Features

• Added support for the following xpath functions in functions.py:
  • xpath
  • xpath_string
  • xpath_boolean
  • xpath_int
  • xpath_float
  • xpath_double
  • xpath_long
  • xpath_short
• Added support for parameter use_vectorized_scanner in function Session.write_arrow().
• Dataframe profiler adds the following information about each query: describe query time, execution time, and sql query text. To view this information, call session.dataframe_profiler.enable() and call get_execution_profile on a dataframe.
• Added support for DataFrame.col_ilike.
• Added support for non-blocking stored procedure calls that return AsyncJob objects.
  • Added block: bool = True parameter to Session.call(). When block=False, returns an AsyncJob instead of blocking until completion.
  • Added block: bool = True parameter to StoredProcedure.__call__() for async support across both named and anonymous stored procedures.
  • Added Session.call_nowait() that is equivalent to Session.call(block=False).

Bug Fixes

• Fixed a bug in CTE optimization stage where deepcopy of internal plans would cause a memory spike when a dataframe is created locally using session.create_dataframe() using a large input data.
• Fixed a bug in DataFrameReader.parquet where the ignore_case option in the infer_schema_options was not respected.
• Fixed a bug that to_pandas() has different format of column name when query result format is set to 'JSON' and 'ARROW'.

Deprecations

• Deprecated pkg_resources.

Dependency Updates

• Added a dependency on protobuf<6.32

Snowpark pandas API Updates

New Features

Dependency Updates

• Updated the supported modin versions to >=0.34.0 and <0.36.0 (was previously >= 0.33.0 and <0.35.0).
• Added support for pandas 2.3 when the installed modin version is at least 0.35.0.

Bug Fixes

• Fixed an issue in hybrid execution mode (PrPr) where pd.to_datetime and pd.to_timedelta would unexpectedly raise IndexError.
• Fixed a bug where pd.explain_switch would raise IndexError or return None if called before any potential switch operations were performed.
