Q4OS 1.8.3 is now the most stable and advanced version of the Q4OS 1.8 “Orion” series, promising to add some more improvements to the in-house built Update Manager application, as well as all the latest security and software updates that have been released upstream in the software repositories of Debian GNU/Linux 8 “Stretch.” As usual, Q4OS 1.8.3 is here only for those who want to deploy the Debian-based operating system on new computers, as existing Q4OS 1.8.x users can have all these updates by simply installing all the available package versions that have been pushed lately into the official stable repos.
