Just updated from the early beta (3.0.1.11) to 3.0.3.9. Painless, but quite long upgrade. No problems so far. Browser seems much better. You dont have to resize the oesf page to click on links any more. Seems far better. I'll check the audio to see if there are any improvements, as pulseaudio has been updated. Seems a bit quicker (less lag), but only just started playing. I'll fo a full review later.
For those interested, you can update from the command prompt with:
ssu release 3.0.3.9
version --dup
Thats it. Takes a long time to download/install, however no issues. I am using an x25 in case anyone wanted to know.
