Summary of Changes

Hello @bestpala, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces the official release announcement for KubeSphere v4.2.1, providing comprehensive details on its new features and improvements. The update focuses on strengthening enterprise-level cloud-native platform foundations through enhanced cluster governance, advanced elastic scheduling capabilities, and unified management of heterogeneous infrastructure, aiming to deliver a more stable, efficient, intelligent, and cost-effective platform.

Highlights

  • Enhanced Cluster Governance: KubeSphere v4.2.1 introduces one-click smooth gateway upgrades, continuous enhancements to multi-cluster governance including online member cluster upgrades and accurate state synchronization, fine-grained node group management, and KubeEye for automated cluster inspection.
  • Advanced Elastic Scheduling: The release integrates Vertical Pod Autoscaling (VPA), Event-Driven Scaling (KEDA) with support for 80+ signal sources, and enhances Horizontal Pod Autoscaling (HPA) with refined control over scaling behaviors, providing a trifecta for resource elasticity.
  • Unified Heterogeneous Infrastructure Management: KubeSphere v4.2.1 provides unified management and adaptation for GPU/vGPU heterogeneous computing resources, deep integration with the Volcano batch scheduling engine, and NFS/object storage local cache acceleration using Fluid for improved data access efficiency.
  • Other Key Updates: General improvements include optimizations in application management (timeout control, log viewing, historical deployment cleanup), enhanced observability (persistent storage for metric/event alarms, Doris backend for audit logs, tenant-level network observability), and resource management (HTTP header probes for health checks, Pod event rolling updates).

Code Review

This pull request adds the release announcement for KubeSphere v4.2.1 in both English and Chinese. The content is well-written, but there are several issues that need to be addressed before publishing. The main problems include:

  1. The filenames for both new articles contain a copy suffix, which should be removed.
  2. A link in both articles points to a clouddev domain, which appears to be a development environment and should likely be a production URL.
  3. There are various formatting inconsistencies in both the Chinese and English versions, such as incorrect punctuation, extra whitespace, and a potential typo in an image URL.

Please address the specific review comments to improve the quality of the articles.

The filename kubesphere-4.2.1-ga-announcement copy.md seems to include a " copy" suffix. It's recommended to rename it to kubesphere-4.2.1-ga-announcement.md for clean URLs and proper file management.

As the first line of defense for production traffic, the stability, observability, and operational efficiency of the gateway directly affect the continuity of core business. In v4.2.1, KubeSphere overhauls the entire gateway lifecycle management capabilities, making significant improvements in operational efficiency and permission governance.
