Both 2.7 and above are simultaneously included, most of the time the 3.x ones are updated to the latest version, but I dont always upgrade to the latest, mostly to the stable version, wheezy I belive it's nicknamed, to not accidentally break a chain of package dependencies.

So you are on Debian, I liked to use some packages in testing (Squeeze ?)
but some stuff it is much better to use the stable version.
