:) well, it was mostly mumbling by the lead developer Rubén. There are a
number of fixes that need to be made and unfortunately things are progressing
very slowly at the moment.
The Trisquel 5 release(s) for instance should really not be prominently
displayed either because it is also lacking security updates. The 4 release
though is still maintained though so that is OK if it works for you to use.
Although that won't be a good release for much longer either.
If you can consider contributing to the project. There isn't enough to
financially keep things moving forward quickly. The lead developer has other
obligations and more contributors would help to (eventually) relieve this
burden. Having a developer able to work on the distribution full time would
really moves things forward much faster.
