I'm having problems getting the Neos to be useful due to the age of the APT sources even after update & upgrade. Are there instructions somewhere for getting it setup with sources that include newer Python 3 releases? Python 3.6 is the first really usable Python 3 version and pip3 doesn't even work until 3.6. I also haven't been able to find a RPi.GPIO_NP for python 3. Python 3.5 has been out of security support for over 2 years now as well.

Can anyone point me to some solutions? I've been googling and searching forums without luck.
