CP5.6.2AN is a great idea, and I'm glad to see it.
However, its existence makes me wonder if the standard CPAN module POD boilerplate is missing a section describing support policy. Many distributions already describe the author's preferred way of handling bug reports, patches, and feature requests, but I can't recall any which limit support to specific versions.
That hasn't been an issue in the past, in part because CPAN encourages upgrading to the most recent version. If older versions will persist, how can authors indicate that they are unsupported?
I realize that many authors disagree with my preferred support policy, and that's fine. I only bring this up because I want to be very clear about how I provide support, so as to avoid unpleasant surprises for everyone later.
