Finally, a word about upgrades. The Package Manager also provides an option to mark all possible upgrades for installation. This will check for all your installed packages if a newer version is available from a repository and, if so, mark this newer version for installation (you can also do this for individual packages). Use this option only with extreme care and only if you have a good reason to replace an existing package by a newer version. The software industry has been very good at conditioning us to believe that “upgrade = newer = better” - which in many cases is simply not true and/or heavily depends on what you intend to do with an application. If an application is stable and does what you need it to do, replacing it by a newer version will - in many cases - not gain you anything but introduce a less mature and less stable product. The applications that ship with Navigatrix have been carefully put together to do what they need to do without getting in each others’ way. Hence Navigatrix may not include the latest available version of an application but one that is robust and works with all the other stuff in Navigatrix. Keep this in mind before upgrading to newer versions of packages (for which there may be good reasons in specific cases).
