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