Bye bye Stagefright 2.0 (and other issues)

Since the discovery of the big vulnerability called Stagefright (summer 2015) some additional were disclosed. Time for an update of the already cyanogenmodded Galaxy S4.
Found a good description of what the names for the different gapps-packages mean: page (includes downloads). I choose pico!

1. 5 min real work: get the ROMs, put them to the SD-card, boot into TWRP; select the nightly, then add also gapps-pico, wipe DALVIK, reboot
2. 20 min waiting: after flashing for first boot-up (self-configuration) .. works like a charm
