- Issues
- Creating a DataFrame from Pydantic models fails if there is missing data/Nones
- `fill_null(pl.lit([]))` on data with enforced schema but no entries makes `to_arrow()` panic
- Columns names with a dot (`.`) do not plot correctly with the new Altair plotting backend
- Enum categories methods
- `pl.from_pandas(df, include_index=True)` does not return the index if it is sorted starting from 0 with step 1 with no name
- Rust documentation does not list all required features for functions
- Alternative method faster and more memory-efficient than ``group_by(..., maintain_order=True).first()`` for larger dfs when operating in fast path
- Repeated sampling for Bootstraping
- Pyarrow polars.exceptions.ComputeError: ArrowInvalid: offset overflow while concatenating arrays with scanning large delta tables
- Incorrect values when performing list arithmetic operations where the inner type is Float32 and sinking to parquet
