Recommendation

Update all MXA910 devices in a configuration to the same firmware version.

Improvements

• Compatibility with Designer 3.1 System Configuration Software
• Network stability enhancements
• Japanese user interface improvements
• Bug fixes

Known Issues

• When exporting Presets using Safari on a Mac OS, the file type is saved incorrectly and must be renamed to .json to be imported
• When attempting to load the device’s web page after using SUU to upgrade or downgrade between MXA 3.1 and earlier releases, the browser may appear to be stuck on the “Loading” screen with the progress bar continually moving. This will typically happen if two upgrades or downgrades are performed within a one-hour period. To correct this, hold your Shift key and click the Refresh button in your browser (or press Ctrl+Shift+R [Win]/Ctrl+F5 [Win]/Cmd+Shift+R [Mac]; note the keyboard shortcut doesn't work on Safari).
