-### New Features
+### Improvements
 
 - Use `split_blocks=True` by default during `to_pandas` conversion, for optimal memory allocation. This parameter is passed to `pyarrow.Table.to_pandas`, which enables `PyArrow` to split the memory allocation into smaller, more manageable blocks instead of allocating a single contiguous block. This results in better memory management when dealing with larger datasets.
