One thing that's bothering me on Ubuntu if a newer version of some software package arrives a day after Ubuntu is released, you need to wait for 6 months till next release to have a newer version and even then you could experience the same thing.
That's usually not the problem, but there are examples of software, especially in scientific computing where every new version brings lot of improvements that we can use. For example, version of matplotlib 1.2 is out, and it finally supports python3.x, that's a great update, but we need to wait for 6 months. 6 months in modern world is lot of time.
Sure, sometimes there are PPAs that can help, and in most cases it's a solid solution, but are there any plans for doing this, I hate to say it but, like in Windows, where we could install the version we like instead of depending on distro releases?
