[Mono-devel-list] Assembly versioning

I read a book once which said the runtime assumes the following versioning
strategy is used:

version format : <Major>.<Minor>.<Build>.<Revision>

The book says, the runtime assumes that when an assembly differs in Build
number or Revision number, it's for bug fixes or something. this means the
assembly should be used then. when an assembly differs minor/major version,
it's an architectural change, so it's not compatible.

The book was .NET XML Developers guide, bought at syngress.
