Hi there,
I have this firmware installed and it works flawlessly.
The Krack fix i cannot check, but DLNA intermittent problems, which i had, seem to be fixed now.
I do not know if it was there in an earlier update, but you can now add an IP-reservation from the connected clients list. Before (at least untill V1.08B04) you had to wait until a device showed up there and then you could change it's credentials.
The fix consists of 2 seperate firmware updates, which have to be done after eachother, so read the readme first and....reset first.
You cannot return to earlier firmware after this update.
Good luck with it, Hugo
