- Speed up `reset_index` for wide dataframes
- BUG: `reset_index` raises ValueError ("cannot insert level_0, already exists") even if the index has a custom name
- BUG: set_index with keys=[pandas.Index, column_name] and drop=False raises KeyError: 'None of [0] are in the columns'
- FEAT: Allow custom engine options in to_sql using ModinDatabaseConnection
- Consider rename `kwargs` parameter in `broadcast_axis_partitions` function to align with `apply_func_args` param
- Do not trigger `.dtypes` computation on `.astype(dtype)`
- BUG: Shallow copy in Modin doesn't copy 'dtypes' when pandas do.
- BUG: subtracting (1, 2) numpy array from (2, 2) dataframe gives ValueError: Unable to coerce to Series, length must be 2: given 1
