REX and Raspbian Stretch
Last week the Raspberry Pi foundation announced a new operating system image based on Debian Stretch.
We have successfully tested REX 2.50.4 with this latest Raspberry Pi OS image. Only our installation scripts on GitHub required minor modifications.
Feel free to upgrade your Raspberry Pi. Remember that it is highly recommended to start from a clean OS image, which is available from the Raspbian downloads page.
Afterwards you can follow one of the Getting started guides in the Documentation and support section, which contain instructions on installing REX runtime modules on your Raspberry Pi.
