Today, at 4:11pm Pacific Standard Time, an era (or at least 9 years) ended. The cpan-testers mailing list, recipient of a all CPAN tests submitted for CPAN testers processing, no longer resends all of those emails to its 50+ subscribers. The last message to be distributed via email should have been #1049514. Further messages will be kept in the archive, http://www.nntp.perl.org/group/perl.cpan.testers (also home to RSS and Atom feeds). Eventually, we're going to transfer to a proper database backed system that doesn't use email at all.
Several people noted that they used cpan-testers to receive notification of new uploads to CPAN. We've created the cpan-uploads mailing list to receive these notifications. Archive/RSS/Atom is at http://www.nntp.perl.org/group/perl.cpan.uploads. You can subscribe by sending a note to cpan-uploads-subscribe at perl.org.
