You might wonder "Hmm, is my Stripe integration affected?" (I sure did!) and the answer is "Almost certainly not." (We've been watching the number of users with outdated versions of TLS on a dashboard for the last several months and actively working on getting people migrated.)
If your integration was affected, it is likely you've gotten a few emails from us and also a notification in your Stripe dashboard. If you don't see a prominent banner when you log in (with additional detail in your Developer tab of the dashboard), you're probably good.
If you have any questions, email email@example.com ; we're happy to help.
(A related topic: we go to fairly substantial efforts to support outdated API versions while still letting us build new features. Amber Feng had a great presentation on it back in the day: https://www.heavybit.com/library/video/move-fast-dont-break-... )
If working on these sort of problems at scale sounds interesting or if you like the idea of working on a team which really sweats the downstream impact of engineering changes, we're hiring and always happy to chat.
I'll try to remember to get you the exact emails tomorrow, and the account name, etc. What do you need to look into it?
I've always heard good things about stripe but like I said this was kinda worrying, because everything we read said June 13th.
