Before this update, deleting an `istag` resource with the `--dry-run=server` option unintentionally caused actual deletion of the image from the server. This unexpected deletion occurred due to the `dry-run` option being implemented incorrectly in the `oc delete istag` command. With this release, the `dry-run` option is wired to the `oc delete istag` command. As a result, the accidental deletion of image objects is prevented and the `istag` object remains intact when using the `--dry-run=server` option.

With this update, the etcd product documentation is updated to include additional requirements for reducing {product-title} cluster latency. 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. For more information, see xref:../etcd/etcd-practices.adoc#recommended-cluster-latency-etcd_etcd-practices[Cluster latency requirements for etcd].
