+## Upgrading
+
+ * If relying on partial caching of content between logged in users, be aware that the cache is now automatically
+   segmented based on both the current member ID, and the versioned reading mode. If this is not an appropriate
+   method (such as if the same content is served to logged in users within partial caching) then it is necessary
+   to adjust the config value of `SSViewer.global_key` to something more or less sensitive.
