Trisquel is still a nice distro, even if you use Trisquel 7. You can update
to the latest linux-libre from third party repos e.g. freesh, or build your
own modern kernels. You can also use Ubuntu PPAs for certain things
(free/libre packages, backported to Ubuntu 14.04, which is what Trisquel 7 is
based on). Trisquel also keeps up to date its ABrowser web browser, which is
a version of firefox, and other applications.
When Trisquel 8 is out, it's likely that an in-place update to it from T7
will be possible.
For those who want something more up to date, Parabola or Hyperbola are good
alternatives to Trisquel.
Parabola is bleeding edge, based on Arch, and FSF endorsed. It's ideal for
development systems or for non-critical desktops. Server/workstation usage is
also possible, if you know what you're doing.
Hyperbola is relatively up to date, and also a libre fork of Arch like
Parabola, but with a focus on debian-like stability and regular release
cycles (ideal for workstations, servers etc). It has a different focus than
Parabola, and although not yet FSF endorsed, it does seem to comply with FSF
criteria and one or two Parabola developers contribute to or have otherwise
moved over to it.
