0.6.0

New Features:

• Added support for vectorized UDFs with the input as a Pandas DataFrame or Pandas Series and the output as a Pandas Series. This improves the performance of UDFs in Snowpark.
• Added support for inferring the schema of a DataFrame by default when it is created by reading a Parquet, Avro, or ORC file in the stage.
• Added functions current_session(), current_statement(), current_user(), current_version(), current_warehouse(), date_from_parts(), date_trunc(), dayname(), dayofmonth(), dayofweek(), dayofyear(), grouping(), grouping_id(), hour(), last_day(), minute(), next_day(), previous_day(), second(), month(), monthname(), quarter(), year(), current_database(), current_role(), current_schema(), current_schemas(), current_region(), current_avaliable_roles(), add_months(), any_value(), bitnot(), bitshiftleft(), bitshiftright(), convert_timezone(), uniform(), strtok_to_array(), sysdate(), time_from_parts(), timestamp_from_parts(), timestamp_ltz_from_parts(), timestamp_ntz_from_parts(), timestamp_tz_from_parts(), weekofyear(), percentile_cont() to snowflake.snowflake.functions.

Breaking Changes:

• Expired deprecations:
  • Removed the following APIs that were deprecated in 0.4.0: DataFrame.groupByGroupingSets(), DataFrame.naturalJoin(), DataFrame.joinTableFunction, DataFrame.withColumns(), Session.getImports(), Session.addImport(), Session.removeImport(), Session.clearImports(), Session.getSessionStage(), Session.getDefaultDatabase(), Session.getDefaultSchema(), Session.getCurrentDatabase(), Session.getCurrentSchema(), Session.getFullyQualifiedCurrentSchema().

Improvements:

• Added support for creating an empty DataFrame with a specific schema using the Session.create_dataframe() method.
• Changed the logging level from INFO to DEBUG for several logs (e.g., the executed query) when evaluating a dataframe.
• Improved the error message when failing to create a UDF due to pickle errors.

Bug Fixes:

• Removed pandas hard dependencies in the Session.create_dataframe() method.

Dependency Updates:

• Added typing-extension as a new dependency with the version >= 4.1.0.
