50*** Canary::Stability COMPATIBILITY AND SUPPORT CHECK
51*** =================================================
52***
53*** Hi!
54***
55*** I do my best to provide predictable and reliable software.
56***
57*** However, in recent releases, P5P (who maintain perl) have been
58*** introducing regressions that are sometimes subtle and at other times
59*** catastrophic, often for personal preferences with little or no concern
60*** for existing code, most notably CPAN.
61***
62*** For this reason, it has become very hard for me to maintain the level
63*** of reliability and support I have committed myself to in the past, at
64*** least with some perl versions: I simply can't keep up working around new
65*** bugs or gratituous incompatibilities, and in turn you might suffer from
66*** unanticipated problems.
67***
68*** Therefore I have introduced a support and compatibility check, the results
69*** of which follow below, together with a FAQ and some recommendations.
70***
71*** This check is just to let you know that there might be a risk, so you can
72*** make judgement calls on how to proceed - it will not keep the module from
73*** installing or working.
