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. |
|
|
