Xperifirm v4.9.1 Changelog
- NEW: Added support for Accessories (currently, just SmartWatch 3).
- FIX: Solved the lag cause by the image loading of each device.
- FIX: Some additional internal changes had to be made as part of the incremental transition of Sony's firmware database from the old servers to the new one. Many of the "grayed out" firmware will no longer appear on XperiFirm, as they are no longer available on Sony servers.
- MINOR: Added a "Available Releases" label for those who don't get the hint that they have to select a release version.
