Mr Philip Muller of Manjaro, announced availability of Manjaro XFCE 15.12 Alpha 2. In the same announcement, Mr Muller also indicates that, Manjaro 15.09 is about to release within few days.
From Release announcement:
We will reach our second version of Calamares in early fall 2015. The Calamares team worked hard to approach this. One big change is now: you can re-use each module in several instances by using different configurations. We now use kpmcore library for the partitioning tool. Some effort will result in luks support for encrypting your installations. Also more and more distro-specific modules got added.
