Parity has fixed the geth account import bug in version 1.3.4. I have decided to give people a choice of backend client they want to use.
This means version 2 will be delayed a bit, but it'll bring with it some new juicy features.
Etherwall v2 will also download the latest backend node binary directly without needing to do full releases each time someone hotfixes an issue in geth or parity.
Other new features will include usage of parity's trace API and tracking of "internal" contract transactions with the parity backend.
