 Changelog
 =========
 
+.. _v2023.4.0:
+
+2023.4.0
+--------
+
+Released on April 14, 2023
+
+.. note::
+
+    With this release we are making a change which will require the Dask scheduler to have
+    consistent software and hardware capabilities as the client and workers.
+
+    It's always been recommended that your client and workers have a consistent software
+    and hardware environment so that data structures and dependencies can be pickled and passed
+    between them. However recent changes to the Dask scheduler mean that we now also require
+    your scheduler to have the same consistent environment as everything else.
