v0.2.0

🚩 This is a HUGE milestone release that fully supports predictive scaling and custom metrics!

✨ Highlight

• Introduce predictive scaling based on the "Traffic-Driven Replicas Prediction" algorithm which has been used on a large scale in production at Ant Group. Try predictive scaling or learn more about the algorithm.
• Fully supports custom metrics for autoscaling with a configuration that is fully compatible with the one used by Prometheus Adapter. Learn more.
