(Actually, that would be 1.6.100, or the 100th point release, if we
stick to using numeric version nomenclature. The vstring version
v1.6.1 would be 1.006001. But I see your point.)
The reason I bring this up is simple semantics: we need a way to
distinguish main trunk from the 1.6 branch for developers. bioperl-
live's VERSION should always be ahead of any CPAN releases so we can
add in a 'use Bio::Root::Foo #.######' if we want to indicate whether
one should use the latest code (trunk) vs. latest release.
One possiblity: we could have trunk's VERSION follow directly after
the latest CPAN release as an alpha, so it would be 1.006000_001. If
we decide that an alpha is necessary for 1.6.1, we release
1.006000_001 and increment trunk to 1.006000_002, otherwise we would
release 1.006001 and trunk would increment to 1.006001_001.
That has a significant downside: bioperl-live becomes a moving target,
so any code reliant on changes only in main trunk would have to
constantly change any version requirements (ick). Another issue that
pops up are scripts expecting trunk ('use Bio::Root::Version
1.006000_001') that would pass for a later point release (1.006001,
for instance, would pass the '1.006000_001' requirement). Double-ick.
Lots of potential confusion best avoided completely, so I think that's
out as an option.

We could continue on with the alternating dev/stable (even/odd minor)
versioning but not release the odd-numbered 'dev' versions to CPAN.
That would allow us to designate trunk as 1.007.
The downside: do we want to risk another long wait between minor

Kind of what I'm thinking, which is a nicer middle ground (it is
pre-1.7, and is a stable target). Anyone else?
