56The following modules will be removed from the core distribution in a
57future release, and will at that time need to be installed from CPAN.
58Distributions on CPAN which require these modules will need to list them as
59prerequisites.
8d374562 60
d228bb8b
TH
61The core versions of these modules will now issue C<"deprecated">-category
62warnings to alert you to this fact. To silence these deprecation warnings,
63install the modules in question from CPAN.
8d374562 64
d228bb8b
TH
65Note that these are (with rare exceptions) fine modules that you are encouraged
66to continue to use. Their disinclusion from core primarily hinges on their
67necessity to bootstrapping a fully functional, CPAN-capable Perl installation,
68not usually on concerns over their design.

100following sections using F<Porting/corelist-perldelta.pl>. A paragraph summary
101for important changes should then be added by hand. In an ideal world,
102dual-life modules would have a F<Changes> file that could be cribbed.
103
104The list of new and updated modules is modified automatically as part of
105preparing a Perl release, so the only reason to manually add entries here is if
106you're summarising the important changes in the module update. (Also, if the
107manually-added details don't match the automatically-generated ones, the
108release manager will have to investigate the situation carefully.)
