Debian's current, supported version is the stable version. The reason why it's only released every two years and why it feels so 'old', is because it takes Debian Developers many months to "further harden" it before release. It wouldn't make sense to release it under a quicker schedule. Debian does offer "rolling" channels with prompt updates (testing, unstable) but those are officially not meant for real, production use.
