Braintree makes regular updates to our server SDKs which follow semantic versioning guidelines. This page will guide you through the largest breaking changes that are specific to the language you are integrating with Braintree. Check the SDK's CHANGELOG for more information on changes.

Ruby Versions

Previous versions of the Ruby SDK supported older, now End-of-Life versions of Ruby. Starting with version 3.0.1, the Braintree Ruby SDK only supports Ruby versions 2.5+.

Google Pay

Previous versions of the Ruby SDK represented Google Pay cards as Android Pay cards to prevent breaking changes. In version 3.0.1, AndroidPayCard and AndroidPayCardDetails were renamed to GooglePayCard and GooglePayCardDetails. See the Google Pay Guide for more details.


Down For Maintenance exceptions have been renamed to Service Unavailable exceptions, since we do not bring our services down to perform maintenance operations anymore.

We also added additional timeout exceptions to give extra clarity on the source (client request vs gateway response).

For more information, check our guide on Exceptions.
