Target customers: Users who use the ECS console security group Features released: 1. When creating a security group, you can create a rule synchronously using the template. This prevents you from forgetting to set rules and thus affecting the use of instances. 2. Security group auxiliary ENI list, using the security group as the entry point, enables you to query all ENIs within the security group. 3. Delete rules in batch. After the console released quick creation of security group rules, many users complain that batch deletion is not available. This feature allows you to delete rules in batch. 4. The list of security groups supports displaying VPC names. The master-slave class interface typically provides ID class data only in the slave data; however, this type of data is not friendly to users, and the console requests friendly data such as display names using ID data. 4. Scheduled migration increases the entry point to create a security group, which is convenient for the user to operate on the security group when performing a scheduled migration. 5. Instance rule summary that summarizes all rules for all security groups to which each instance is a member. It is convenient for users to troubleshoot and see which ports are enabled or disabled and what security groups they belong to.
