# Installed software version and info
The first information shown is the current version of the installed system software, in M.m.v format, where
- M = Major version number, whose advancement indicates a completely renewed software version, and which usually involves breaking changes with lower M versions;
- m = minor version number, whose progress indicates a version with new features, which typically do not involve breaking changes with the same version of M;
- p = patch number, the progress of which indicates a software version that includes fixes and corrections to problems found on previous versions, with the same M and m.
If the installed version is the latest, a “Help” link is shown which opens a popup with general information on how to perform an update.
Conversely, if a more recent version is available, the link shows an indication "New version available! (M.m.v) "with its identification number; in this case, if necessary, read up on the changes made by the new version and, if possible, update the system following the instructions in the popup.
