Subject: [Boost-users] [serialization] Best way to serialize to an old file version
From: Richard Ulrich (richi_at_[hidden])

What is the best way to write archives to an old version? Say I have
version 23 of our product and want to write an archive that another user
with version 22 can read. The serialization keeps track of the version
on a class level. But in this use case I need to know the version of
each class at a specific point in time. Sure, I could implement some
global variable and completely work around the version system of boost
serialization. But I hope there is a better, preferred way.
