The CentOS Stream mirror continues to provide continuous updates, with new releases starting from CentOS Stream 9. Recent updates to the mirror include EULA and license files modified on August 25, 2025. Importantly, CentOS Stream mirrors (for versions 9 and 10) are rolling updates and include the latest security patches and feature fixes. In contrast, EOL CentOS Linux versions (such as CentOS 7, EOL June 30, 2024; CentOS 8, EOL December 31, 2021) no longer receive official security patches, with their repositories offline. Users continuing to use EOL versions for learning or testing can switch to the vault.centos.org archive source to install historical packages, though no new security fixes will be available. To check for updates, CentOS Stream users should maintain default official or mirror sources, while EOL CentOS Linux users can verify their system version with cat /etc/os-release and switch to vault sources if needed.
