 - Added support for mapping `np.percentile` with DataFrame and Series inputs to `Series.quantile`.
 - Added support for setting the `random_state` parameter to an integer when calling `DataFrame.sample` or `Series.sample`.
 
+#### Improvements
+
+- Enhanced autoswitching functionality from Snowflake to native Pandas for methods with unsupported argument combinations:
+  - `shift()` with `suffix` or non-integer `periods` parameters
+  - `sort_index()` with `axis=1` or `key` parameters
+  - `sort_values()` with `axis=1`
+  - `melt()` with `col_level` parameter
+  - `apply()` with `result_type` parameter for DataFrame
+  - `pivot_table()` with `sort=True`, non-string `index` list, non-string `columns` list, non-string `values` list, or `aggfunc` dict with non-string values
+  - `fillna()` with `downcast` parameter or using `limit` together with `value`
+  - `dropna()` with `axis=1`
+
 #### Bug Fixes
 
 - Fixed a bug in `DataFrameGroupBy.agg` where func is a list of tuples used to set the names of the output columns.
