+===========================
+
+Security Notes
+--------------
+
+- rustdoc would execute plugins in the /tmp/rustdoc/plugins directory
+  when running, which enabled executing code as some other user on a
+  given machine. This release fixes that vulnerability; you can read
+  more about this on the [blog][rustdoc-sec]. The associated CVE is [CVE-2018-1000622].
+
+  Thank you to Red Hat for responsibily disclosing this vulnerability to us.
+
+Compatibility Notes
+-------------------
+
+- The borrow checker was fixed to avoid an additional potential unsoundness when using
+  match ergonomics: [#51415][51415], [#49534][49534].
