API7 Gateway 3.5.0

Release Date: 2025-01-27

Features

Data Plane

• Multiple Upstreams in a Service: For advanced scenarios such as canary deployments, blue-green deployments, or managing multiple clusters, a service can now utilize multiple upstreams. In such cases, a default upstream serves as the primary target for most requests, while other upstreams can be used for specific purposes, such as routing traffic to a canary deployment or a secondary cluster. See the renewed Configure Canary Traffic Shifting for details.

• Supported custom configuration of DP metrics label through Prometheus (opens in Plugin Hub docs) plugin metadata.
• Optimized performance of data plane Prometheus metrics reporting.
• [Beta] Configured mTLS for upstream. API support is currently available. Full support is coming soon.
