I think there may have been some misunderstanding here.  Support for
Version 2.2 is not being "phased out", at least not in the sense that
I would understand the meaning of "phased out".   We are still answering
questions about it, and we will continue to do what we can to help out.
It's just that what we can do for old software is not nearly as good as
what we can do for current software.

As we have all undoubtedly experienced in many ways, maintaining old
software (or old anything) becomes increasingly difficult as the software
gets older, and eventually becomes so difficult that the difficulty
exceeds the interest in doing it.  It would be pretty hard (and very
expensive) to support any software in perpetuity.

Version 2.2 isn't quite that old yet, but it's getting there.  It is
already so old that it would be misleading to claim that we can support
it at the same level of effectiveness that we can support current versions
of the software.  Lack of use, fading memories, deteriorating hardware,
and the tremendous need to keep up with newer (and often incompatible)
technologies are already having a significant effect.  So I suppose one
could say that support for Version 2.2 is being "phased out" in the sense
that we are concentrating much more heavily on newer releases, and are
recommending that people interested in high-quality support should
consider upgrading to more recent software.
