Specific info needed from Cambridge CXN v1 users

Hi,

I would like to know if any of all of the feature below that were introduced in the CXN v2 model are also available on the CXN v1 (older model) through subsequent firmware updates:

1. mpeg-DASH and HLS based internet radio support

2. Chromecast built-in

In essence is there any difference now (after all firmware updates till now) between the V1 and V2 apart from the faster processor of the latter?

Thanks.
