The first beta of the new version will be released next week. Thank you for your patience - there were quite a lot of small bugs to find and fix before the release.
We are also looking at creating more robust signing scheme with GnuPG, and we will add the fingerprint of our certificate in another "public" ETH transaction from our main devfee account, which will be announced in advance. This will add additional layer of security, making impossible for someone to try releasing fake versions of PhoenixMiner.
