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.
Previous versions of the Braintree Python SDK supported Python 2. Starting with version 4.0.0, the SDK supports Python 3.5 and higher.
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.
