When can I expect the new firmware? I only see limited beta’s, (I’m always to late :-(), but the features and bugfixes in it are wanted!!
No one knows – not even WD (because they are still working out issues).
It will come when it comes, grasshopper. Patience is good.
If you are really anxious to try one of the Betas, a bit of googling will turn up links to downloads if you look hard enough.
