Yes, there was an update. Go to your Dashboard and click the Read More link under the Latest Improvements sidebar entry.

We have a firmware update ready that will improve your machine’s ability to connect to our servers. Most printers will update the next time you turn your Glowforge off and on. However, if you reboot your system and it doesn’t connect to Wi-Fi, please follow the instructions on setup.glowforge.com. This will reset your connection and ensure the update is downloaded.
