Hi everyone,

Just a heads up that we released a few more changes to our API bindings over the last week:

== API Libraries

  - stripe-go version 15.1.0 has been released. Changelog: https://github.com/stripe/stripe-go/blob/master/CHANGELOG 

  - stripe-java version 2.6.0 has been released. Changelog: https://github.com/stripe/stripe-java/blob/master/CHANGELOG

Also, on a special note: we're updating our iOS SDK with flexible, prebuilt UI components to more easily collect your users' payment information. If you're building an iOS app that accepts payments and would like to try out these changes, please email ja...@stripe.com.

Thanks!
