Philip Müller, Manjaro Development Team recently announced the second release candidate of Manjaro Linux 15.12-rc2 (Capella). This is one of the biggest updates we did so far. Mostly due the C++ 11 ABI change within gcc. With this update, Plasma 4 is been dropped for good. All users of this desktop should either switch over to Plasma 5 or any other maintained desktop, like LXQt. Manjaro Linux 15.12-rc2 update: Now have Plasma 5.
