- Fixed a bug in `session.get_session_stage` that referenced a non-existing stage after switching database or schema.

- Fixed a bug where using the `explode` function in dynamic table creation caused a SQL compilation error due to improper boolean type casting on the `outer` parameter.
- Fixed a bug where using `to_pandas_batches` with async jobs caused an error due to improper handling of waiting for asynchronous query completion.

### Snowpark Local Testing Updates

- Improved `pd.to_datetime` to handle all local input cases.
- Create a lazy index from another lazy index without pulling data to client.
- Raised `NotImplementedError` for Index bitwise operators.
- Display a clearer error message when `Index.names` is set to a non-like-like object.
- Display a more clear error message when `Index.names` is set to a non-like-like object.
- Raise a warning whenever MultiIndex values are pulled in locally.
- Improve warning message for `pd.read_snowflake` include the creation reason when temp table creation is triggered.
- Improve performance for `DataFrame.set_index`, or setting `DataFrame.index` or `Series.index` by avoiding checks require eager evaluation. As a consequence, when the new index that does not match the current `Series`/`DataFrame` object length, a `ValueError` is no longer raised. Instead, when the `Series`/`DataFrame` object is longer than the provided index, the `Series`/`DataFrame`'s new index is filled with `NaN` values for the "extra" elements. Otherwise, the extra values in the provided index are ignored.

- Fixed a bug where `Series.reindex` and `DataFrame.reindex` did not update the result index's name correctly.
- Fixed a bug where `Series.take` did not error when `axis=1` was specified.

#### Behavior Change
## 1.21.1 (2024-09-05)

- When calling `DataFrame.set_index`, or setting `DataFrame.index` or `Series.index`, with a new index that does not match the current length of the `Series`/`DataFrame` object, a `ValueError` is no longer raised. When the `Series`/`DataFrame` object is longer than the new index, the `Series`/`DataFrame`'s new index is filled with `NaN` values for the "extra" elements. When the `Series`/`DataFrame` object is shorter than the new index, the extra values in the new index are ignored—`Series` and `DataFrame` stay the same length `n`, and use only the first `n` values of the new index.
### Snowpark Python API Updates

- Fixed a bug where using `to_pandas_batches` with async jobs caused an error due to improper handling of waiting for asynchronous query completion.
