I got an email alert from Strava stating that they’re making some changes to their login flow on Oct 15th. In that email, they say:
> Look out for another email with comprehensive details about refresh tokens and the migration period on October 15, 2018.
But that’s too late - I may not be able to update my code between the time that their explanation email comes and the time that they switch over the authentication flow, _assuming_ they send the email before they make the change.
I’ve emailed their development team to try & get further details, but there’s a chance that logins will stop working tomorrow and won’t work again until I get details from them **and** release code to sort things out.
😬

It doesn’t seem like anyone was affected by this, and I’m releasing code now that updates CityStrides with Strava’s new authentication system. 👍 🚀 🎉
You shouldn’t notice any of these changes. Let me know if something goes wrong for you, though (use [this form](https://citystrides.com/contact) if you also can’t log in here for some reason).
