version control
how does NSIS handle seemless (if user is connected, new components are automatically installed) version control?
With commands like GetDLLVersion, GetDLLVersionLocal, GetFileTime and GetFileTimeLocal. Have a look at the UpgradeDLL macro for an example.
You can also read value from the registry if you have information there using ReadRegStr and friends, and ReadINIStr for INIs. It's also possible to read from text files using FileOpen, FileRead and FileClose.
