### Được hỗ trợ từ các trình soạn thảo


Toàn bộ framework được thiết kế để sử dụng dễ dàng và trực quan, toàn bộ quyết định đã được kiểm thử trên nhiều trình soạn thảo thậm chí trước khi bắt đầu quá trình phát triển, để chắc chắn trải nghiệm phát triển là tốt nhất.

### **Network**

#### **IPv6**

*   [alpha] IPv6 support has been added. Notable IPv6 support details include:
    *   Support for IPv6-only Kubernetes cluster deployments. **<span style="text-decoration:underline;">Note:</span>** This feature does not provide dual-stack support.
    *   Support for IPv6 Kubernetes control and data planes.
    *   Support for Kubernetes IPv6 cluster deployments using kubeadm.
