Neosmartblinds broken after latest upgrade

Getting the following error message when checking configuration.

Platform error ‘cover’ from integration ‘neosmartblinds’ - cannot import name ‘SUPPORT_CLOSE’ from ‘homeassistant.components.cover’ (/usr/src/homeassistant/homeassistant/components/cover/init.py)

the file _init_py contains only some commented out header text.

When using an older version of HA no errors. Can anybody assist with resolving my issue.
Thanks.

Has no one else had an issue?
