Debian distributes versions 1.4 and 1.5.2 of Bioperl, but considers
using 1.5.2 in its next stable release. We welcome your comments on this
as well.
I think the consensus here would be that 1.5.2 is the appropriate version of Bioperl to use in the next stable release of Debian. Although we've started to work toward Bioperl 1.6, that release will be at least a few months off, and 1.4, while technically our most recent 'stable' release, is waaay out of date.
