# *** 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.
# ***
# *** The stability canary says: (nothing, it was driven away by harsh weather)
# ***
# *** It seems you are running perl version 5.024000, likely the "official" or
# *** "standard" version. While there is nothing wrong with doing that,
# *** standard perl versions 5.022 and up are not supported by JSON::XS.
# *** While this might be fatal, it might also be all right - if you run into
# *** problems, you might want to downgrade your perl or switch to the
# *** stability branch.
# ***
# *** If everything works fine, you can ignore this message.
# ***
# *** Stability canary mini-FAQ:
# ***
# *** Do I need to do anything?
# *** With luck, no. While some distributions are known to fail
# *** already, most should probably work. This message is here
# *** to alert you that your perl is not supported by JSON::XS,
# *** and if things go wrong, you either need to downgrade, or
# *** sidegrade to the stability variant of your perl version,
# *** or simply live with the consequences.
# ***
# *** What is this canary thing?
# *** It's purpose is to check support status of JSON::XS with
# *** respect to your perl version.
# ***
# *** What is this "stability branch"?
# *** It's a branch or fork of the official perl, by schmorp, to
# *** improve stability and compatibility with existing modules.
# ***
# *** How can I skip this prompt on automated installs?
# *** Set PERL_CANARY_STABILITY_NOPROMPT=1 in your environment.
# *** More info is in the Canary::Stability manpage.
# ***
# *** Long version of this FAQ: http://stableperl.schmorp.de/faq.html
