Folks,
We have just pushed out DendroPy 3.4.0. Many under-the-hood tweaks and
fixes, but the biggest changes involve better NeXML support and some
changes to how node ages are referenced and handled.
You can get the latest (and always greatest) from:
http://pypi.python.org/pypi/DendroPy
We also now have a formal citation for DendroPy:

for phylogenetic computing. Bioinformatics 26: 1569-1571
