Upgraded to 0.97.2 should have seen an update to the pyecobee API (from 0.0.18 to 0.0.21) but didn't?

I followed the instructions here: https://www.home-assistant.io/docs/installation/hassbian/installation/#updating to upgrade HA 0.96.2 to 0.97.2 which seemed fine. I was looking forward to an update for the pyecobee API (0.0.18 has a bug that sends large amounts of data to ecobee)

… but when I look in /srv/homeassistant/lib/python3.7/site-packages I still see: python_ecobee_api-0.0.18.dist-info

Did I miss a step?
