It is as Magic Bannana said we are downstream of other distros. For example
the current version of Trisquel (5) is based off Ubuntu 11.04 which at the
time of this post is roughly 8 months old. Trisquel releases tend to happen
approximately 4 months after their corresponding Ubuntu release because of
the work involved. As Magic Bannana also mentioned there is only one main
developer. It isn't like we have a massive billion dollar company backing us
(i.e. redhat).
The main concern for us here is freedom. While it is nice to sometimes have
the latest and greatest with limited resources it isn't always possible. So
in these sort of cases we will let upstream do the packaging. If/when Ubuntu
packages that driver into their distro it will make it's way into the
corresponding Trisquel release. Unfortunately we just don't have the
resources to package the latest versions of everything.
If you would like to help the project out we would LOVE that. Here are
[https://trisquel.info/en/wiki/how-help some ways you can help]. Packaging
software would be one way if that particular piece of software is of
importance to you. Thanks!
