If you don't notice the dates, or are doing numerical version number
comparisons, 1.6002 (an RC) is greater than 1.60 (the release). It may
not be automatic, but you can still chose to download the developer
releases. Which means if we say to someone 'use Bioperl 1.6 or better'
they may choose to get the latest version and think it is 1.6002 when
infact 1.60 was the more recent version. 1.6010 solves the problem, is
consistent with your 1.50_10 suggestion, and doesn't cause any problems
as far as I can see.

How did you get Bundle::BioPerl updated? Did you just ask Chris
Dagdigian to do it for you? Or do you have access to his account? I'll
ask Ewan about it.
