This is a repo issue:
https://api.github.com/repos/mozilla/geckodriver/releases/latest seems to point to 0.30.0 (not 0.31.0) for some reason.

I was in the process of setting up some automation when I noticed this discrepancy.

Could you correct this one-off and tweak your release process to ensure that "latest" is properly pointed/updated?
