I think we should be flexible to make this practical, the core of the
idea is that you should not get any surprises when upgrading just "b",
and no API surprises when upgrading "m".
There's a question about whether the API should be defined as the
source API, or also the runtime API, for extensions. I think "the
API" should cover both.

Huh? Does strnatcmp() know the that 2.0RC4 is newer than 2.0b2? :-)

We'll need to add something like that. Either a function, a standard
method or when ZE2 comes a static class variable.
