SmartGate Version 3.5.1

Release Date: October 20, 2025

Version Overview

SmartGate 3.5.1 fixes critical startup issues based on 3.5.0 and integrates etl_proxy 2.0.0 and STM 1.4.7.0 plugins.

• ✨ Core Update Highlights:

  • Fixed startup failure issue caused by missing TLS configuration (affects version 3.5.0);
  • etl_proxy 2.0.0 new architecture: Refactored underlying protocol, improved system stability (requires platform ≥3.7.0.0, K8s not currently supported);
  • Enhanced host tag management: Added SMARTGATE_HOST_TAG / SMARTGATE_HOST_ATTR environment variables, automatically injects cluster name br.cluster.name.

• ⚠️ Important Limitations:

  • APM < V2.6.0: No batch forwarding, data sent directly without cache;
  • APM < V2.10.0: K8s YAML display anomalies;
  • APM < V3.5.1: K8s YAML incompatible with SmartGate 3.3.0.

::: tip Upgrade Recommendation

• All users should upgrade from 3.5.0 to 3.5.1 as soon as possible to resolve startup compatibility issues;
• If using etl_proxy 2.0.0, must ensure One platform version ≥ 3.7.0.0, and cannot be deployed in K8s environments;
• It is recommended to configure new environment variables for more granular resource grouping and monitoring.
