June 2017: v29 firmware
July 2018: v30 beta - and, to my knowledge, never left beta
March 2019: v31 beta.
Last message from Zoltan - March 2019. And he's, two my knowledge, the only one working on PockEthernet. Well, there's another engineer added, but haven't seen any message from him.
So, two years without production-status updates, hardly any communication - so yes, looks like the product is dead indeed.
