To standardize ENS control operations and improve user convenience, ENS plans to update certain APIs, console operation restrictions, and behaviors as detailed below:

• Instance Release: ReleasePrePaidInstance, ReleasePostPaidInstance
  • Before change: Instances could only be released when in the "Stopped" state.
  • After change: Instances can be released regardless of their current state.
• Password Reset: ModifyInstanceAttribute
  • Before change: Password reset was allowed only for instances in the "Stopped" state, and the system automatically started the instance after resetting the password.
  • After change: Password reset is supported for both "Running" and "Stopped" instances. For "Running" instances, the new password takes effect only after the user manually restarts the instance. For "Stopped" instances, the new password takes effect only after the user manually starts the instance.
• Custom Data Injection: ModifyInstanceAttribute
  • Before change: Custom data injection was allowed only for instances in the "Stopped" state, and the system automatically started the instance afterward.
  • After change: Custom data injection remains limited to "Stopped" instances, but the system will no longer automatically start the instance after injection—users must manually start the instance themselves.
• Key Pair Binding/Unbinding: AttachKeyPair, DetachKeyPair
  • Before change: Key pair binding/unbinding was allowed only for instances in the "Stopped" state, and the system automatically started the instance after the operation.
  • After change: Key pair binding/unbinding is supported for both "Running" and "Stopped" instances. For "Running" instances, the changes take effect only after the user manually restarts the instance. For "Stopped" instances, the changes take effect only after the user manually starts the instance.
