+prelude: >
+    Several in-tree documentation updates exist in newton-1.
+    An important bug 1570789 that will handle 4 byte unicode
+    chars for metadefs APIs is fixed which will prevent 500s
+    on the same. Deprecated sign-the-hash approach for image
+    signing and old run_tests and related scripts have been
+    removed.
+upgrade:
+  - The image signature verification feature has been updated
+    to follow the "sign-the-data" approach, which uses a
+    signature of the image data directly. The prior deprecated
+    "sign-the-hash" approach, which uses a signature of an MD5
+    hash of the image data, has been removed.
+security:
+  - The initial implementation of the image signature
+    verification feature in Glance was insecure, because it
+    relied on an MD5 hash of the image data. More details can
+    be found in bug 1516031. This "sign-the-hash" approach was
+    deprecated in Mitaka, and removed in newton-1.
+    Related CVE-2015-8234.
