Open Source : How Do You Stay Up To Date?

I Love the concepts and beliefs behind Open Source. I use Open Source libraries, applications etc. all the time. One of the things I have always found a challenge though, is knowing when a new release comes to be.

Not only that, is this a simple point release, a major release or a security release. For the most part I want to stay up to date, especially with the libraries I use, when a security releases is made. Currently I play the, I hope I have the most stable, most secure version. Howeaver, I always thought that having a single place that I can sign-up to be informed about releases would be awesome.

Do you have a way to do this or, are you subscribing to a multitude of RSS feeds and mailing lists to stay informed?
