Upgrade your APIs safely with Progressive Rollouts in a Python FastAPI Application

LaunchDarkly's free plan now includes progressive rollouts, allowing developers to release features gradually and monitor for any issues that may arise. This tutorial demonstrates how to use this feature in a Python FastAPI application to upgrade to a new API version. By gating updates with a LaunchDarkly flag, developers can control the pace of their releases and ensure a smooth transition to the latest version. The example provided showcases how to set up a progressive rollout for an API update, allowing users to see new features at a controlled rate while minimizing potential risks.
