I confirm that because one of their maintainers is also a team mate in Debian,

With my Debian maintainer hat on: exactly as Thiago said. But with a note: we
have always tried to ship a version as close to an LTS as we could (and I know
the same goes for Ubuntu, as one of my team mates prepares Ubuntu's Qt packages
from what we do in Debian). This is because it's normally easier to get the
patches from a LTS. But the point remains the same.
