nginx 1.30.0 Released with Default Keepalive Connections and New Features

📌 nginx 1.30.0 was released, consolidating features and fixes from the 1.29.x mainline series. A key operational change is that keepalive connections to upstream servers are now enabled by default, with the proxy HTTP version set to 1.1, whereas previously this required explicit configuration. The update includes protocol support additions, security-relevant fixes, and new configuration options. No specific CVEs, dates beyond the release context, or detailed impact assessments were provided in the announcement. The changes primarily affect upstream server configurations in nginx deployments.
