So you can define precisely which version must be upgraded from wich version.
A situation you often have is that you have a small patch for a version, but it is only necessary for end-users who upgrade from a specific built to your latest version. All other end-users do not need the patch.
With the integrated Release Manager you can define exactly in what conditions a patch is installed. In fact, LizaJet Installer will not even download a patch when it is not needed.
For each package separatly, and for each build, you can define the version number for upgrading.
WIth LizaJet Installer you can add and remove individual components of your application after first installation.
