+    crush: fix has_v4_buckets()
+    
+    alg, not type!
+    
+    This bug made us incorrectly think we were using v4 features when user type
+    5 was being used.  That's currently 'rack' with recent crush maps, but
+    was other types for clusters that were created with older versions.  This
+    is clearly problematic as it will lock out non-hammer clients incorrectly,
+    breaking deployments on upgrade.

+    osd: fix negative degraded objects during backfilling
+    
+    When there is deleting requests during backfilling, the reported number of degraded
+    objects could be negative, as the primary's num_objects is the latest (locally) but
+    the number for replicas might not reflect the deletings. A simple fix is to ignore
+    the negative subtracted value.

  Release Notes
 ===============
 
-v0.94.1 Hammer (draft)
-======================
+v0.94.1 Hammer
+==============
+
+This bug fix release fixes a few critical issues with CRUSH.  The most
+important addresses a bug in feature bit enforcement that may prevent
+pre-hammer clients from communicating with the cluster during an
+upgrade.  This only manifests in some cases (for example, when the
+'rack' type is in use in the CRUSH map, and possibly other cases), but for
+safety we strongly recommend that all users use 0.94.1 instead of 0.94 when
+upgrading.
+
+There is also a fix in the new straw2 buckets when OSD weights are 0.
+
+We recommend that all v0.94 users upgrade.
