There is a keyError for RELEASE_TAG variable

because there is no environ variable with key name RELEASE_TAG

code:

os.environ['RELEASE_TAG'] in /usr/lib/python3/dist-packages/sphinx/config.py is trying to fetch the RELEASE_TAG variable value , which is not present in os.environ

so it is throwing KeyError: 'RELEASE_TAG'

solution :

I commented these two lines and run make
it works

#version = os.environ['RELEASE_TAG']
#release = version

hi megha-an,
i found

version = os.environ['RELEASE_TAG']

on freedom-e-sdk/doc/sphinx/conf.py line 27

release = version

on freedom-e-sdk/doc/sphinx/conf.py line 29

and then commit
it works, thanks.
