Today we publish a new set of live and installation media for the 10.0 series, that applies all package upgrades and security fixes to date, and corrects bugs in the installer applications and package managers. If you are already using Trisquel 10 you can upgrade without reinstalling, simply by using your package manager or update application of choice, or by running these two commands on a terminal:
sudo apt update
sudo apt dist-upgrade
The new release iso images are available in the downloads page.
