You can always download, e.g., 'http://www.perl.com/CPAN/modules/02packages.details.txt' - this would give you a list of all the latest and greatest - but what for? If you just want the latest version of the module, that happens automatically when you download from CPAN.

If you just want your modules to stay up-to-date, you can do what the CPAN documentation recommends: set up a cron job (or whatever the equivalent is in Windows) to run the following on, say, a weekly schedule:

perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
