#### Improvements

- Hybrid execution mode is now enabled by default. Certain operations on smaller data will now automatically execute in native pandas in-memory. Use `from modin.config import AutoSwitchBackend; AutoSwitchBackend.disable()` to turn this off and force all execution to occur in Snowflake.
- Downgraded to level `logging.DEBUG - 1` the log message saying that the
Snowpark `DataFrame` reference of an internal `DataFrameReference` object
has changed.
