This update clarifies the prerequisites and setup procedures for using etcd, resulting in an improved user experience. As a result, this feature introduces support for Transport Layer Security (TLS) 1.3 in etcd, which enhances security and performance for data transmission, and enables etcd to comply with the latest security standards, reducing potential vulnerabilities. The improved encryption ensures more secure communication between etcd and its clients.
