Unfortunately editing the Ubuntu Wiki/help pages requires to subscribe to a special group now, so I won't write such a page. However, the information computer newbies need is very simple. Major releases always should be backwards compatible and should be without regressions, IOW 1.1, 1.2, 1.3 should be backwards-compatible. >From one major release to another no backwards-compatibility should be expected. IOW version numbers are not random numbers, they usually make sense. A good exception is the kernel, it might not be backwards-compatible, that's why rtirq needs fixes from time to time, but at least regressions are unwanted for the kernel, sure, they sometimes happen, especially for patched kernels. A very bad exception are soname issues e.g. not long ago introduced by GTK 3.20. The soname of a lib is the major version. Software is compiled against the soname, which usually is a link against a dot release.
