I've made a new build of wpa_supplicant / wpa_gui based on development branch of upcoming v2.7 version (labled v2.7-devel.RC1).
There are a lot of updates compared to our current v2.2. Most notable the fix for KRACK.
This build of wpa_supplicant is meant as a replacement of the version v2.2 included with xwlan/wlanstat.
Moreover there is also included wpa_gui. This is a QT frontend which enables you to manage your wireless profiles without xwlan/wlanstat.
