As to when new client will be ready for release the short answer August without factoring in Murphy's law.
We expect to rebase after Peter gets back from holiday, even if we managed to do it before he would not want the client released while away in case we did get an unexpected fork.He will need to be available during the process.
The forum kinda needs a "like" button - nice work guys it's great to see an active dev team.
I think that's most likely the quickest route to failure, dev's that lose interest or just created a pump and dump coin.
Keep it up and I'm sure there's a community of us willing to help out too (in whatever way we can)
