Is there a service/software where I can subscribe to/create notifications for releases of specific software packages such as Git or JDK? Necessary features would be free as in beer, updates fetched from the official web site (in other words, no third party repositories), and the possibility to create my own searches. Nice features would be existing notifications for well-known software, free as in freedom, and notifications with either email or web feeds.
I need to know of the release of the sources to compile into a custom package.
