Why do the Repositories not have the latest upstream versions?
I tried installing some software using apt-get or default software manager. Unfortunately, it didn't install the newest available software, e.g. conky installed version is 1.8.1, while the newest is 1.9, NetBeans is 7.0.1 instead of 7.1.2. What should I add or what should I change to install the newest software?
