+> [!IMPORTANT]
+>
+> This package is now in maintenance mode,
+> meaning that important bugs will be fixed if possible but we won't adding new features in the next few weeks / months.
+>
+> The focus of future development is on a completely rewritten version (`neopolars`) that currently exists in the `next` branch.
+> The package in that branch will become the new `polars` package once the rewrite is complete.
+>
+> Please check the GitHub issue #1152.
