You can find the update only in Xbins. The live update server is still working but the response header that the dash is expecting have changed. This build contains fix for that as well, so Live Update will again work with this version (save for the next update of course).
Also, the build will say 582, but it really is 583

Additional note on FAT32 USB devices. My 60GB mobile disk is kinda working, but it's only able to mount the first partition (I have FAT32/FAT32/NTFS). Also, it times out very often so I don't really consider it as working. Write operation should be avoided with these devices as more than likely, it will fail in the middle.
What operation works with FAT32 devices: File Explorer Read/Write, Image Viewer. MP3 playback is sketchy at best, still need to optimize the read operation. Notepad, Unrar, Zip/Unzip is not supported.
The updates you see in the list have actually been in there since latest WIP. I just didn't have a chance to release it due to my situation. The new things I've added in the past 3 weeks are the fix to Unrar, SlideShow and FAT32 support.
Hope you enjoy this release
