I upgrade manually when threads from our helpful members appear, such as this one.
I download the newer version in My Downloads ( a file I created ) and just write over or upgrade the new version. Once it is launched, I reboot for both the latest Beoport and Beoplayer. It is supposed to be automatic, but it is a more clean upgrade, and old habits die hard.
A few minutes to upload everything again, and it is finished. To date, no lost any photo, radio, or music files.
