as they mentioned in previous comment:
Most importantly, this release should fix problems with sending shielded payments and publishing polls.
no, it's not the same thing. I'm talking about the ability to back up shielded addresses
Please note private coins/shielded addresses arent live yet, the only implementation so far is for making polls and bets, the recent update fixes the making polls issue, which had to do with how you pay to make polls using shielded txs... private coins (actual shielded addresses you can back up) will come in a later update when anonymous polls update arrives... but thats down the line in the roadmap after poll reviews, poll explorer redesign and auto refunds for losing bets or opinion polls.
