How do you keep track of new packages?
I'm currently using Arch Linux but although it's a nice distribution, I'm missing Slackware a bit.
One thing I do like about Arch with respect to Slackware is that if say a new version of MPlayer comes out, it will automatically be downloaded and installed through pacman.
However on Slackware if a new version of MPlayer was released I wouldn't know about it.
Basically what I'm asking is how do you keep track of when updates to the programs you use are released?
I would have thought some good solutions would be somehow synchronizing with SourceForge/Freshmeat which would e-mail (or through RSS) you information about new builds.
Another solution would be to subscribe to the mailing lists of each of the programs but I doubt all the packages I use have a mailing lists, though I'm not sure?
So, how do you do it?
