It's not that bad, your scheme :). Personally, I like the way the dynamic
libraries on *nix are done. They consist of three parts:
We increase the first if we break the ABI (either the runtime or the class
libraries, or introduce any other breaking changes in the toolchain etc.). We
increase the second one if we add new class libraries/methods without breaking
the ABI. The third is increased every time we do a release that's netiher #1 or
#2 above. Of course, it can lead to version numbers like 2.1.12314, but the
version part increase rules can be defined a bit differently to what I outlined
above. The idea is that each part of the release version should have a real and
clearly defined meaning.
