+    Rebuilt Blazar containers using the upstream Blazar source code, instead of
+    the StackHPC fork. The StackHPC fork was based on an older version of
+    Blazar, but contained additional features relating to coral credits, which
+    are now no longer in use.
+deprecations:
+  - |
+    The StackHPC-specific Coral Credits features of Blazar are no longer
+    included, and the Blazar source has been reverted to the upstream default.
