We are still working on the Joomla update.
Yes, it definitely works. Almost all Javascript issues you may see after an update are down to browsers caching JS files.
One thing you can try is enabling the "bust JS" option in the debug tab of the global Fabrik options. This will add a unique query string arg when loading JS files, which should force your browsers to reload. You can then turn it off again.

This is like God sent...I had been grilled by my superior for this issue. They ask why me as a user need to manually clear the cache should you be taking care of all theseLeaving bust turned on will prevent browsers from caching the JS files. So yes, it's a performance hit.
Best bet is to leave it turned on for a few days after updating, to force a reload for your regular users.
