WD Live Streaming - Most Stable Firmware

I just bought the WD Live Streaming box and was wondering which firmware seems the most stable. I want to stream netflix and youtube for my child. I plan  to connect wirelessly and am using Verizon Vios as my ISP. Which firmware is best for my purpose? Thanks in advance to the community for their help.

You can download the latest one 1.11.14.
