We're running Centos 7 which has a python version that identifies as 2.7.5 (even though it probably contains many backported patches from later versions). Unfortunately, this prevents us from using pip to update ftrack-python-api from 1.8.0 to 1.8.1. (the previous version didn't have the requirement of Python >=2.7.9).
Is there something in 1.8.1 that warrants the minimum Python version? I'll download it manually for now to see if it works...
