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