We have just released version 0.9.0 of the Hologram Python SDK for the Nova. This version has the same features as version 0.8.3 but has been updated to require Python 3 instead of Python 2.
All install scripts have been updated so you should be able to follow existing procedures to perform the upgrade.
Our scripts will install Python 3, but will not remove Python 2 or make Python 3 the default version of Python on your system. Its up to you if you want to do that. If you are upgrading, the script will remove the old SDK from the Python 2 setup and install it on Python 3. It should still work even though Python 2 might still be the default Python version on the system.
We know some of you have been waiting for this for a while and we hope this helps with your projects.
