+------------------
+
+We're pleased to announce the release of dask-image 2023.08.0!
+
+Highlights
+
+This version fixes bugs related to processing CuPy backed dask arrays
+and improves testing on GPU CI. It drops support for python 3.8 and
+adds pandas as a dependency. As a feature improvement, the dask-image
+equivalent of ``scipy.ndimage.label`` now supports arbitrary
+structuring elements.
+
+For full support of all GPU functionality in dask-image we recommend
+using CuPy version 9.0.0 or higher.
