Release announcement feed/mailinglist/subforum

I installed NC from .tar.gz download, and I’m not frequently logging into the web UI as admin. How can I stay updated on new releases, especially security relevant ones? Is there a subforum (dedicated to only release notifications, no advertisement like in ), a mailing list (like, though this was not 100% updated, AIUI), or a dedicated RSS feed ( contains other stuff, is useful but only indirectly related to updates)?

If not, would it be possible to provide that?
