There was a bug causing issues with the PayPal Payflow Pro integration that would result in an "Invalid Amount" error when attempting a payment using a culture other than "en" or "en-US". That issue has now been resolved.

Performance improvements were implemented to speed up throughput on crucial endpoints such as POST /transactions/pay. Load testing in the sandbox environment shows a 20% improvement in throughput with a 46% reduction in response time. We will continue to monitor these changes in the sandbox environment before pushing them to production.
