The version of this module was broken

Amon2::DBI 0.31 has bug.: transaction management bug
Math::Random::MT 1.15 has bug.: rand() took no notice of argument RT #78200
Module::Install 1.04 has bug.: Broken, http://weblog.bulknews.net/post/33907905561/do-not-ship-modules-with-module-install-1-04

Recommended XS module for better performance

JSON::XS is recommended: If you are using JSON.
HTTP::Parser::XS is recommended: If you are using Plack.
Linux::Inotify2 is recommended: If you are using Filesys::Notify::Simple.

Recommended version to enable good feature

Amon2 <= 3.29 does not have: JSON hijacking detection.
Log::Minimal <= 0.10 does not have: LM_COLOR
Log::Minimal <= 0.08 does not have: colourful logging
Log::Minimal <= 0.03 does not have: ddf
Proclet <= 0.12 does not have: Proclet::Declare
DBI <= 1.614 does not have: AutoInactiveDestroy

Recommend modules when using ...

I recommend to install LWP::Protocol::https, if you are using LWP.: Need to support https
