+  * Fix the lazy loading of images from some websites bug 1727967.
+  * Move certain font family defaults from serif to sans serif bug
+    1727982.
+  * SeaMonkey 2.53.9.1 uses the same backend as Firefox and contains
+    the relevant Firefox 60.8 security fixes.
+  * SeaMonkey 2.53.9.1 shares most parts of the mail and news code
