 # NEWS
 
+> [!IMPORTANT]
+>
+> This package is now in maintenance mode, and the possibility of adding new features in the future is low.
+>
+> The focus of future development is on a completely rewritten version that currently exists in the `next` branch.
+> The package currently named `neopolars` in that branch will become the new `polars` package in the future.
+>
+> Please check the GitHub issue #1152.
