This version contains upgraded websocket push libraries (moving away from jquery push methods to plain javascript push). The side effect of this is that end users may get a "unable to load push" message when upgrading from any previous version(s) in a BIG RED BANNER at the top of the page when opening the client or administrator web interfaces after upgrading to this version.  If a user obtains this message, they should clear their browser cache or reload the page bypassing and refreshing the local cache (CTRL+F5 or Shift+Click Reload Button) or equivalent in the end-user's browser.

Future upgrades will not require this step as HTTP headers should now disable caching and the proper version should always be downloaded.
