Updating Stripe to fix broken API; see who updated the API and when?

Here’s the API upgrade that broke things: https://stripe.com/docs/upgrades#2018-02-05

It won’t

Asked Stripe (through the on-page feedback thing, which usually gets answers) the question outright:

Can i see who updated the API version and when? Or does the fact that it says “DEFAULT” mean it got updated to that automatically? Yes, trying to figure out who broke things ;-)

what statement descriptor will Stripe use by default?

Stripe did write back and acknowledge they should greatly increase the prominence of API versioning in their development and API documentation.
